Description

The unit is located at the Institute of Advanced Chemistry of Catalonia (IQAC-CSIC), in Barcelona and it is coordinated by the Colloidal and Interfacial Chemistry Group, led by Dr. Carlos Rodríguez. The unit is focused on the characterization of nanostructures in liquids and liquid/liquid interfaces, such as micelles, liposomes, micro- and nano-emulsions, and nanoparticles. The unit features state-of-the-art instrumentation for the determination of various parameters such as size distribution and zeta potential (surface charge), critical micelle concentration (CMC), solubilization capacity, osmolarity, surface and interfacial tension, wettability, refractive index, turbidity, colloidal stability, density, viscosity and other rheological parameters (shear and elastic moduli, critical yield stress, etc.)

Practical Sessions in the Master of Cosmetic and Dermopharmacy by NANBIOSIS U12

The researchers of NANBIOSIS U12, Nanostructured liquid characterization unit of CIBR-BBN and IQAC-CSIC, will participate in teaching and training students of the Master en Cosmética y Dermofarmacia, organized by Centro de Estudios Superiores de la Industria Farmacéutica (CESIF), from 17 May to 16 June 2021. Cosmetic manufacturing companies are committed to innovation, both in technological development and in the use of components in their formulations, adapting to new trends and user needs. Determination of colloidal stability, surface tension, particle size and rheological behaviour, among many others properties, is essential for the proper characterization and understanding the performance of cosmetic products.[...]

Gels formed from the interaction of lipid vesicles: Influence of charge in their structural and rheological properties

Susana Vilchez, researcher at NANBIOSIS U12. Nanostructured liquid characterization unit  of CIBER-BBN and IQAC-CSIC, is coauthor of an article recently published in the Journal of Molecular Liquids. “This work – explains Susana Vilchez – shows how structural and viscoelastic properties of a lipid colloidal gel can be altered by varying the ratio of charged lipids in the dispersion. These findings corroborate that the eventual formation of the gel and the morphology of its network is governed by the repulsive potential of the particles instead of the molecular composition of their membranes. Thus, the right control of charge balance in the system may[...]

Encapsulation of BSA/alginate water–in–water emulsions by polyelectrolyte complexation

Researchers of NANBIOSIS U12. Nanostructured liquid characterization unit from CIBER-BBN and IQAC-CSIC have recently published an article entitled Encapsulation of BSA/alginate water–in–water emulsions by polyelectrolyte complexation in the scientific journal Food Hydrocolloids The research which results are published involves the encapsulation of drops of water-in-water emulsions, which could be used as vehicles for the administration of active principles. Characterization of emulsions and capsules was performed in the Unit 12 of NANBIOSIS Nanostructured Liquid Characterization Unit. Water-in-Water (W/W) emulsions were prepared in aqueous mixtures of an anionic polyelectrolyte (sodium alginate, NaAlg), with a globular protein (bovine serum albumin, BSA). This combination showed phase separation[...]

NANBIOSIS U12 expands its capabilities with a new SEM for morphological and dimensional characterization of solid samples

The U12 of NANBIOSIS (Nanostructured liquid characterization unit) has expanded its capabilities with a new equipment U12-E22. SEM Hitachi TM4000Plus II for morphological and dimensional characterization of solid samples Low vacuum Scanning Electron Microscopy with two electron detectors (secondary, SE, and backscattered, BSE). SE imaging provides a detailed information of the morphology of the sample and BSE gives information about the different components of the sample, based on the different atomic number (the higher the atomic number, the brighter the surface). The equipment can apply different vacuum levels (using a turbo molecular pump) with accelerating voltages between 5 and 20[...]

NANBIOSIS U12 researchers modify contact lenses to reduce the risk of bacterial infection

Researchers from NANBIOSIS U12 Nanostructured liquid characterization unit, from CIBER-BBN at the IQAC-CSIC have chemically modified contact lenses, incorporating antibacterial properties. Contact lenses, especially soft ones, pose a risk of ocular microbial infection that can eventually lead to loss of vision. “These new contact lenses inhibit the formation of bacterial biofilms and could prevent ocular keratitis” explains Jordi Esquena, a researcher at the CIBER-BBN at the IQAC-CSIC and one of the coordinators of the work. In the study, published in Colloids and Surfaces B: Biointerfaces, bactericidal activity was introduced into hydrogel contact lenses, through antimicrobial peptides that were anchored on[...]

Ethylcellulose nanoparticles as new “in vitro” tool for cell transfection

Researchers of NANBIOSIS U12 Nanostructured liquid characterization unit and U29 Oligonucleotide Synthesis Platform (OSP) of CIBER-BBN at IQAC-CSIC have obtained successfully ethylcellulose nanoparticles with positive zeta potential formed from nano-emulsion complexation with an antisense oligonucleotide which result very promising complexes for “in vitro” cell transfection. A new non-viral gene delivery vector has been developed, based on ethylcellulose, an easily available and low cost carbohydrate polymer, “generally recognized as safe” by the FDA. Although ethylcellulose is nonionic, positively charged nanoparticle dispersions have been obtained using nano-emulsion templates in cationic:non-ionic surfactant-based systems. The nanoparticles have been successfully complexed with negatively charged phosphorothioate antisens[...]
