Description

Located at the Research Center onNanoscience and Nanotechnology(CIN2), CSIC, at the campus of Universidad Autónoma de Barcelona (UAB) the Biodeposition Unit consists of a versatile and automated molecular printer that can dispense minute volumes of solutions (from atto to femtoliter volumes) on a wide variety of surfaces to create user-defined patterns of spots or lines with high spatial resolution. The system is suitable for the functionalization of biosensors with any kind of biomolecule, nanoparticles, graphene or other nanostructures,for surface patterning for cell culture, or for the preparation of micro/nanoarrays, among other applications. The laboratory also harbors a Surface Plasmon Resonance (SPR) service. The Unit is coordinated by Prof. LauraM. Lechuga, group leader from the Nanobiosensorsand Bioanalytical Applications Group (nanoB2A) at CIN2-CSIC.

Label-free DNA-methylation detection by direct ds-DNA fragment screening using poly-purine hairpins

Prof Laura Lechuga, Scientific Director of NANBIOSIS Unit 4 Biodeposition and Biodetection Unit, has led the research whose results have been published by Biosensors and Bioelectronics  with the title  “Label-free DNA-methylation detection by direct ds-DNA fragment screening using poly-purine hairpins” Cancer diagnosis continuously evolves due to the better understanding of tumorigenic processes. DNA-methylation is consolidated as an effective biomarker for cancer prognosis and diagnostic even in tumors of unknown origin. The reversibility of this epigenetic mechanism also places it as a high-profile tool for the development of more sophisticated and personalized therapies. Current methodologies, such as bisulfite conversion or PCR amplification, rely on complex[...]

Nanoplasmonic biosensor device for the monitoring of acenocoumarol therapeutic drug in plasma

As a result of the collaboration carried aout by two units of NANBIOSIS, U4. Biodeposition and Biodetection Unit and U2. Custom Antibody Service (CAbS), it has been developed a compact and simple nanoplasmonic sensing device based on gold nanodisks for the rapid monitoring of acenocoumarol, using highly specific polyclonal antibodies produced against the drug Acenocoumarol (Sintrom®) which implies: A label-free nanoplasmonic device for the rapid monitoring of acenocoumarol in plasmaD. Direct quantification in real time requiring low sample volume is achieved. Non-specific interferences from plasma are minimized using the developed methodology. Excellent accuracy has been observed measuring blind plasma samples. Potential to be implemented as a POC devic[...]

Gold/Silver/Gold Trilayer Films On Nanostructured Polycarbonate Substrates For Direct And Label‐Free Nanoplasmonic Biosensing

Laura Lechuga, Scientific Director of NANBIOSIS U4. Biodeposition and Biodetection Unit is coathor of the article “Gold/Silver/Gold Trilayer Films On Nanostructured Polycarbonate Substrates For Direct And Label‐Free Nanoplasmonic Biosensing” published by Ultrasmooth gold/silver/gold trilayer nanostructured plasmonic sensors were obtained using commercial Blu-ray optical discs as nanoslits-based flexible polymer substrates. A thin gold film was used as an adhesion and nucleation layer to improve the chemical stability and reduce the surface roughness of the overlying silver film, without increasing ohmic plasmon losses. The structures were physically and optically characterized and compared with nanostructures of single gold layer. Ultrasmooth and chemically stable trilayer nanostructures with a surface roughness <0.5 nm[...]
