It is located at the Institute of Advanced Chemistry of Catalonia (IQAC-CSIC), in Barcelona and is coordinated by the Colloidal and Interfacial Chemistry Group, led by Dr. Concepción Solans, pioneering in Spain in the characterization of nanostructures in liquids and liquid/liquid interfaces. It counts with several laboratories perfectly equipped with singular instruments for nanostructured liquids characterization.
It counts with the techniques for the study of nanostructured liquids. Specifically, using both aser light and small-angle X-ray scattering, this unit is able to measure the size distribution, morphology and aggregate number in colloidal dispersions such as micelles, vesicles, micro- and nano-emulsions, as well as particle dispersions.
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. For[...]
Conxita Solans, Scientific Director of Unit 12 of NANBIOSIS together with researchers of her group, Colloidal and Interfacial Chemistry of CIBER-BBN and IQAC-CSIC and the Department of Pharmacy and Pharmaceutical Technology, University of BarcelonaIn have published the research paper “Versatile Methodology to Encapsulate Gold Nanoparticles in PLGA Nanoparticles Obtained by Nano-Emulsion Templating” in the journal Pharmaceutical Research. The scientists have shown that a novel and very versatile methodology has been developed for the production of polymeric nanoparticles loaded with gold nanoparticles. In this work, gold-nanoparticles (AuNP) have been encapsulated in polymeric nanoparticles using a novel and versatile methodology based on nano-emulsion templating, whic[...]
Conxita Solans, Scientific Director of the Unit 12 NANBIOSIS is co-author of the research article recently published a research article in the journal Applied Materials & Interfaces. Carbon nanofibers (CNFs) with high surface area (820 m2/g) have been successfully prepared by a nanocasting approach using silica nanofibers obtained from chromonic liquid crystals as a template. CNFs with randomly oriented graphitic layers show outstanding electrochemical supercapacitance performance, exhibiting a specific capacitance of 327 F/g at a scan rate of 5 mV/s with a long life-cycling capability. Approximately 95% capacitance retention is observed after 1000 charge–discharge cycles. Furthermore, about 80% of capacitance is[...]
Jordi Esquena, Scientific Coordinator of Unit 12 of NANBIOSIS, has recently published an interesting review in the journal Current Opinion in Colloid & Interface Science, about W/W emulsions. Dr. Esquena describes the general background of research in the field and focuses on recent scientific advances and applications. Water-in-water (W/W) emulsions are colloidal dispersions of an aqueous solution into another aqueous phase. Such dispersions can be formed in mixtures of at least two hydrophilic macromolecules, which are thermodynamically incompatible in solution, generating two immiscible aqueous phases. Highly stable water-in-water emulsions can be formulated using fully biocompatible and edible components, and consequently,[...]
In the frame of ECIS 2016, the 30th Conference of the European Colloid and Interface Society (ECIS), Rome 4-9 September, 2016, a special Symposium honouring Conxita Solans was organized on September 8th – 2.00-5.00 pm. Conxita Solans, Scientific Director of Unit 12 of NANBIOSIS, has during many years been one of the leading scientists in the field of surfactants and dispersions. She has been very active in ECIS, presenting her research results at several conferences, being President and also organizing one ECIS meeting in Barcelona.[...]
Conxita Solans, Scientific Director of the Unit 12 NANBIOSIS, received last July 4 in the opening ceremony of the congress Formula VIII, the award Pierre Fillet 2016, given by the Formulation Group of the French Chemical Society (SCF). The prize was awarded to Dr Solans in recognition to her contributions on formulation of colloidal systems, namely on the design and characterization of Nanostructured Liquids such as nano-emulsions, microemulsions, micelles, etc, developed through Unit 12 of NANBIOSIS. Pierre Fillet was a major force behind formulation in France particularly and across Europe, he was one of the instigators of the first Formula[...]
Dr. Conxita Solans, Scientific Director of the Unit 12 NANBIOSIS, has been awarded with the Micelle Prize, by the Spanish Committee of Detergents, Surfactants and Related Products (CED) The award was presented to Dr. Conxita Solans during the International Congress Formula VIII (Barcelona 4 to 7 July 2016), The Formula Conferences cover all aspects in Formulation Sciences and Technologies and constitute a frame for knowledge transfer and dialogue between Academia and Industry. This annual event is organized jointly by various European Societies namely the French Chemical Society (SCF), the British Formulation Group of the Royal Society of Chemistry (FSTG/RSC), t[...]
