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.)

NANBIOSIS ICTS invites groups and companies to discuss Smart Biomaterials and devices for Drug Delivery

On February 22nd, the National School of Health of the Carlos III Health Institute hosted the forum on Smart Biomaterials and biomedical devices for applications in drug delivery and regenerative medicine, organized by the ICTS Nanbiosis, an infrastructure shared by the CIBER-BBN and the Center of Minimally Invasive Surgery Jesus Usón (CCMIJU). This is the first groups/companies meeting organized by Nanbiosis, in which about 70 B2B meetings  were held. The meeting brought together about 40 participants from 14 research groups (from the CIBER-BBN and the CCMIJU) and 10 companies, which discussed the latest advances in the research lines developed by the groups[...]

DHA and l-carnitine loaded chitosan hydrogels as delivery systems for topical applications

The journal JCR Colloids and Surfaces A: Physicochemical and Engineering Aspects, has recently publish and interested article which show the results of the research lead by Jordi Esquena, Coordinator of Unit 12 of NANBIOSIS,. The formation of biocompatible hydrogels of chitosan crosslinked with genipine deposited on textile substrates has been studied and the incorporation and release of active ingredients for cosmetic applications has been investigated. The active principles studied have been dihydroxyacetone (DHA), which produces a sunless tanning effect; And carnitine, used as anti-cellulite agent. The results have shown that crosslinking with chitosan allows controlling the release rate of the active ingredients,[...]

Elastic and adhesion properties of adsorbed hydrophobically modified inulin films on latex particles using Atomic Force Microscopy (AFM)

In a study published in the journal Colloids and Surfaces A: Physicochemical and Engineering Aspects, by Jordi Esquena, Coordinator of Unit 12 of NANBIOSIS, among others, it has been shown that the latex particles dispersed with graft-type polymeric surfactants have excellent colloidal stability, which is attributed to the repulsion forces between the particles, which arise from the presence of adsorbed surfactant molecules. These forces of repulsion have been studied by means of Atomic Force Microscopy (AFM), between an AFM tip and a latex particle, with the presence of surfactant adsorbed on both. It has been observed that this repulsion is maintained even[...]

Methods for the In Vitro Characterization of Nanomedicines —Biological Component Interaction

An interesting article has been recently published, in the journal Personalized Medicine In the context of a public-private collaboration between Cristina Fornagera of Sagetis-Biotech and Conxita Solans, Scientific Director of Unit 12 of NANBIOSIS This review summarizes the main techniques used to assess the interaction of nanomedicines with biological systems, highlighting their advantages and disadvantages. The translation of knowledge from novel designed nanosystems at a research laboratory scale to real human therapies is usually a limiting or even a final point due to the lack of systematic studies regarding two aspects: nanoparticle interaction with biological components and nanoparticle cytotoxicity.
