Atomic Force Microscopy (AFM): Principles, Modes, and Emerging Applications in Nanotechnology and Biomedicine

Discover how Atomic Force Microscopy (AFM) provides nanometric precision in imaging, mechanical analysis, and electrochemical characterization of surfaces. Explore real-world applications in nanotech, semiconductors, and biomedicine.

Introduction

Atomic Force Microscopy (AFM) is a cutting-edge surface characterization technique that enables researchers to explore surfaces with nanometer-scale precision. Unlike optical or electron microscopes, AFM uses a mechanical probe to scan and measure the surface topography, material properties, and interactions at the atomic level.

The versatility of AFM allows it to operate in various environments, including air, vacuum, and liquids. This makes it ideal for a wide range of applications, from materials science to biomedicine. It provides both qualitative imaging and quantitative analysis of topography, mechanical elasticity, electrical properties, and more.

As advanced as it is adaptable, AFM enables the development of new semiconductors, high-performance polymers, bio-compatible coatings, and real-time biological measurements at the molecular scale. With the integration of specialized modes and AI-driven software, the Bruker Dimension Icon-PT AFM, for example, brings even greater efficiency and precision to modern nanoscale research.

Understanding the fundamentals of AFM

Atomic Force Microscopy was invented in 1986 by Binnig, Quate, and Gerber. Its original design has since evolved into a family of techniques that share one common feature: the interaction between a sharp probe tip and a surface.

The basic components of an AFM system include:

• Cantilever and Tip: A nanometer-scale tip mounted on a flexible cantilever that interacts with the sample.
• Laser and Photodetector: A laser beam reflects off the back of the cantilever and onto a photodetector, tracking vertical displacement.
• Piezoelectric Scanner: Controls the movement of the sample or the probe with sub-nanometer accuracy.
• Feedback System: Maintains a constant force or height to allow precise mapping of the surface.

AFM does not rely on light or electrons to generate images. Instead, it uses force interactions, such as van der Waals, electrostatic, or capillary forces, to sense the features of the surface. This makes it especially suitable for non-conductive samples, unlike SEM or TEM.

Additionally, AFM can function in air, liquids, or controlled gas environments, enabling real-time biological and chemical analysis under near-physiological conditions. This environmental adaptability is a major advantage in biosanitary research.

AFM working modes explained

Atomic Force Microscopy offers multiple operational modes, each designed for specific material types and analytical goals.

Contact Mode

In contact mode, the probe remains in constant contact with the surface as it scans. This mode provides high-resolution imaging but can be invasive, especially for soft or biological samples. It is best suited for hard, stable surfaces such as metals, glass, and ceramics.

Tapping Mode (Intermittent contact)

Tapping mode oscillates the cantilever at its resonance frequency and gently touches the surface during each cycle. This reduces lateral forces and sample damage, making it ideal for imaging soft polymers, biological tissues, and loosely bound nanoparticles.

Non-contact Mode

In non-contact mode, the cantilever vibrates near the surface without touching it. It detects attractive van der Waals forces, offering the least invasive method for delicate or loosely bound surface features.

Other advanced Modes

In addition to the former, there are advanced AFM modes worth mentioning, such as PeakForce QNM®, KPFM, and TUNA.

• PeakForce QNM®: Measures mechanical properties (modulus, adhesion, deformation) at <1 nN forces with nanometric resolution.
• Kelvin Probe Force Microscopy (KPFM): Maps electrostatic surface potential and work function.
• TUNA/CAFM: Enables current mapping for electrical conductivity in semiconductors and nanomaterials.

These advanced modes enable multi-parameter surface mapping in a single scan, drastically improving data acquisition and analysis capabilities.

HPLC: What It Is, How It Works, and Its Applications in Modern Biotech

Discover what HPLC is, how it works, and why it’s essential in analytical chemistry and biotechnology. Learn about real applications like LC/MSD iQ integration for antibody purification.

What is HPLC? Understanding High-Performance Liquid Chromatography

High-Performance Liquid Chromatography (HPLC) is one of the most powerful analytical techniques used in chemistry, biochemistry, and biotechnology. From pharmaceutical quality control to the purification of cutting-edge biotechnological products, HPLC provides high-resolution separation and precise quantification of complex mixtures. Its precision, sensitivity, and versatility have made it indispensable in both research and industrial settings.

This article explores how HPLC works, its key components, real-world applications —including the integration of mass detectors like the Agilent LC/MSD iQ— and how this technique is evolving toward automation and AI-enhanced scalability.

How does HPLC work? Core principles and mechanism

At its core, HPLC is a technique for separating, identifying, and quantifying the components of a mixture by exploiting their interaction with a stationary phase and a liquid mobile phase under high pressure.

Mobile and stationary phases

The mobile phase is a liquid solvent or a mixture of solvents that carries the sample through the system. The stationary phase is typically a column packed with small, porous particles (often silica-based) that interact differently with each compound.

As the mobile phase flows under high pressure through the stationary phase, each component in the sample moves at a different rate depending on its chemical characteristics and interaction with the column material.

Retention time and elution

Every compound elutes from the column at a different retention time. This is a key indicator used to identify and quantify substances. The sharper and more distinct the elution peaks, the more effective the separation.

Types of HPLC

HPLC can be tailored to different applications through various modes:

• Isocratic Elution: A constant mobile phase composition throughout the run.
• Gradient Elution: Varies the composition of the mobile phase to improve separation of complex mixtures.
• Reverse-Phase HPLC (RP-HPLC): The most common form, using a nonpolar stationary phase and polar mobile phase.
• Normal-Phase HPLC, Ion-Exchange HPLC, and Size-Exclusion HPLC are also used based on the molecular properties of the analytes.

Key components of an HPLC system

Understanding each part of the system is essential for appreciating its versatility and precision, as well as to help understanding how it can benefit from the analytical potential of this technique.

1. Solvent delivery system (Pump)

The pump delivers the mobile phase through the column at a precise and constant flow rate, often between 0.5 to 1.5 mL/min, under pressures of up to 6000 psi.

2. Injector and sample introduction

The injector introduces the sample into the mobile phase. Manual or autosampler injectors are used depending on the system’s automation level. This provides the column with a mixture of the sample and the mobile phase.

3. Column: The Heart of HPLC

This is where the separation happens. Columns vary in length, diameter, and particle size depending on the application. Different types of columns can be used depending on the nature of the sample. Reverse-phase C18 columns are the most widely used in pharmaceutical and biotech labs.

4. Detectors: UV vs Mass Spectrometry (MS)

Traditional systems use UV-Vis detectors to measure absorbance. However, newer systems incorporate Mass Spectrometry (LC-MS) for enhanced specificity. Mass detectors can identify compounds based on molecular weight, offering far superior sensitivity and selectivity.

HPLC vs LC-MS: Enhanced analytical power

Combining HPLC with Mass Spectrometry (LC-MS) brings unmatched analytical power, especially when dealing with complex biological samples. This is thanks to their superior analytical capabilities compared to traditional detection approaches.

The role of LC/MSD iQ integration

At NANBIOSIS Unit 2 (CAbS), researchers have integrated the Agilent G6160A LC/MSD iQ mass selective detector with the Agilent 1260 HPLC system to significantly enhance immunoreagent analysis.

This configuration enables:

• Specific molecular mass detection
• Rapid confirmation of compound identity
• Higher selectivity than UV detectors, even for overlapping peaks
• Improved purification protocols

Advantages over traditional UV detection

Traditional UV detectors may struggle with closely eluting or co-eluting compounds, especially in bioanalytical samples. LC-MS eliminates this by providing a mass fingerprint for each analyte, ensuring better resolution and reducing false positives.

Real Case: Immunoreagent characterization

NANBIOSIS experts at Unit 2 (Custom Antibody Service) use LC/MSD iQ for:

• Monitoring the purity of antibodies
• Quantifying specific immunoreagents
• Characterizing molecular forms for regulatory compliance

This setup supports biotech development pipelines and technology transfer from lab to industry, highlighting the practical utility of this cutting-edge analytical technique.

Understanding Zeta Potential: Surface Charge at the Solid/Water Interface and Its Role in Modern Materials Science

Explore the importance of zeta potential and surface charge at the solid/liquid interface for biomaterials, membranes, and nanomaterials.

What is Zeta Potential and why does it matter?

Zeta potential is a key physicochemical parameter that describes the electrostatic potential at the slipping plane of a solid surface in a liquid medium. It is not a direct measure of surface charge but rather the potential at the boundary between the stationary layer of fluid attached to the surface and the mobile layer of the surrounding liquid. This parameter is crucial for understanding the behavior of colloidal dispersions, emulsions, and particles in suspension.

The phenomenon of zeta potential emerges from the formation of the electrical double layer (EDL) at the interface between a solid and an aqueous solution. This layer consists of a charged surface and a compensating layer of counter-ions. When an external field is applied, the movement of these ions relative to the surface creates an observable potential difference.

Zeta potential impacts the stability of colloidal systems: high absolute values (positive or negative) indicate strong electrostatic repulsion, which helps prevent aggregation. Conversely, low values may signal a risk of flocculation or sedimentation. Hence, it is a critical metric in formulating stable suspensions in pharmaceuticals, cosmetics, food products, and beyond.

Surface charge at the solid/water interface

The solid/water interface is a dynamic region where charge develops due to several mechanisms: ionization of surface groups, ion adsorption, and lattice defects. The type and density of surface charge depend strongly on pH, ionic strength, and the nature of the surrounding electrolyte.

This surface charge is the origin of the electrical double layer and directly influences interactions with dissolved molecules, proteins, or ions. In biological and environmental systems, it governs key processes such as adsorption, desorption, ion exchange, and membrane transport.

In materials science, understanding surface charge is essential for tailoring materials with desired wettability, adhesion, or biocompatibility. This is especially relevant in applications involving membranes, coatings, and nanostructures that operate in aqueous environments.

How Zeta Potential is measured: techniques and technologies

Several techniques are used to determine zeta potential, including electrophoretic light scattering (ELS) for colloidal systems and streaming potential or streaming current methods for solid surfaces. Among advanced tools, the SurPASS 3 Electrokinetic Analyzer stands out for its ability to directly measure the zeta potential at the solid/liquid interface.

SurPASS 3 uses the classical electrokinetic approach with continuous flow: an electrolyte is passed through a channel formed between the sample surface and a reference, and the resulting flow potential or flow current is measured. This allows for precise, non-destructive analysis of a wide variety of sample geometries, including flat surfaces, powders, fibers, and porous materials.

Moreover, SurPASS 3 integrates automated pH titration using syringe pumps, enabling the determination of the isoelectric point (IEP). This is invaluable for tracking surface modifications and understanding material behavior across different pH levels. This equipment is available in the services of our Unit 16, among other surface characterization techniques.

Happy Day of Chemistry! The role of Chemistry in a sustainable research in health

Today, November 15 is a day of celebration for us, the Day of the Chemistry in Spain!

Chemistry is the science that studies matter, how it is composed, its properties and how its structures are transformed and, as matter is everything, including living beings and ourselves, we can say that chemistry is omnipresent and transversal in all areas surrounding us. Chemistry is everywhere, we ourselves are chemistry and our health and our life is chemistry.

“Everything around us is chemistry in the environment, foods, what we use and what we touch every day. Our own body is a sophisticated complex factory with an infinite number of chemical processes taking place on a perfect and synchronized manner”- points Pilar Marco, Scientific Director of NANBIOSIS U2 Custom Antibody Service (CAbS) from CIBER-BBN at IQAC-CSIC.

The crucial role of chemistry in everyday life is also evidence in the development of current technology and the economy. According the VCI Prognos Study, the Global growth forecast for Industrial Sectors, places the chemical industry in the fist position. As far as national picture, the INE Statistics on R+D Activities 2020 -last publish report-, chemical and pharmaceutical industry employs the 22,2 % of research staff recruited and the investment and expenditure on the chemical and pharmaceutical industry represents the 23,6% R+D and Innovation -above the motor vehicles industry.

Thanks to chemical and pharmaceutical research,

medicines, vaccines and health products have made great strides in fighting diseases and improving quality of life. Thanks to chemical and pharmaceutical medicine research, in few years, it will be possible, for example, to count on smart implants delivering personalised drugs only where cancer or infections are detected or biosensors circulating in our body to find diseases only one week after infection.

At the Institute of Advanced Chemistry of Catalonia, four NANBIOSIS units of CIBER-BBN use chemistry to deliver new therapeutic and diagnostic approaches that improve the quality of life of the society.

One of the research lines of the Nb4D group-U2 CabS at IQAC-CSIC (led by Pilar Marco and Nuria Pascual) focuses on the chemical signals that bacteria emit to communicate with each other and thus develop virulence mechanisms. Their knowledge will allow the development of new therapeutic and diagnostic strategies to mitigate the serious problem of antimicrobial resistance.

NANBIOSIS U3 Synthesis of Peptides Unit– MS4N group, led by Miriam Royo, explores the use of diverse types of chemical multivalent platforms (oligomers, dendrimers, polymers, micelles and lipid nanovesicles) for the development of drug delivery systems for cancer treatment, protein delivery systems for the treatment of lysosomal diseases and macromolecular compounds that have intrinsically therapeutic properties with application to central nervous system diseases.

Chemistry plays an essential role in helping society achieve Sustainable Development Goals (SDGs)

In 2015 the United Nations created a universal call to action to end poverty, protect the planet, and ensure that all people enjoy peace and prosperity by 2030. This framework, comprising 17 aspirational goals known as the Sustainable Development Goals (SDGs)

Chemistry is key to achieve the SDG 3: Good Health & Well-Being with the development of new technologies that will provide a deeper understaunding of human health, making posible better, cheeper and faster medical diagnosis and treatmens.

In this sense, Carlos Rodriguez Abreu, Scientific Director of NANBIOSIS Unit for the characterization of nanostructured liquids (U12) explains: “The goals of sustainable development are producing a shift towards surfactants not based on petroleum derivatives, but derived from other raw materials that are more biocompatible and that allow a circular economy that is less aggressive with the environment. Quality control is necessary with regard to the properties of the products that contain surfactants, such as the droplet size in emulsions, the particle size in suspensions, their colloidal stability over time, among others. Additionally, products must be precisely formulated to optimize the use of raw materials and obtain the desired properties. In this context, the NANBIOSIS U12, acredited with ISO 9001:2015 by AENOR, offers a wide range of advanced analysis techniques for the determination of different colloidal properties such as droplet size and particle size, colloidal stability, viscosity, surface tension, pore size distribution, and determination of phase behavior and structure for the tailor-made formulation of surfactant and colloid systems for pharmaceutical and biomedical applications.

The Nucleic Acid Chemistry group at IQAC-CSIC – NANBIOSIS U29 Oligonucleotide Synthesis Platform (OSP) is developing new compounds based in DNA and RNA to detect and treat diseases participating in several projects with several research and industrial partners such as La Marato de TV3 (Covid), Oligofastx, Caminan2, Osteoatx. These new drugs use the natural mechanisms for gene regulation to treat undruggable diseases such Muscular dystrophy and others. Importantly special attention is made to design novel synthetic protocols to produce less organic waste what contributes to the sustainable development. 

We wish to all the family of chemistry professionals new projects and inspiration to achive humans Good Health & Well-Being and keep the world moving!

And Happy Chemistry Day, too, for all the chemistry enthusiasts!
