Clara Mª Pereyra LópezGraduated in Chemistry at the University of Cadiz (1991), I started my research activity in the field of Phase Equilibrium Thermodynamics, with the theoretical-experimental study of the saline effect in the distillation of aqueous mixtures, subject of my degree thesis (1992). Later, and thanks to the concession of a European project, I reorient my research work to the phase equilibrium with supercritical fluids, field in which I carried out the Doctoral Thesis (1996), after several research stays in the University of L’Aquila (Italy). After a further postdoctoral stay at the same university (2001) and with the concession of the project PPQ2003-04245 “Generation of ampicillin microparticles by the SAS technique using supercritical carbon dioxide” I was once again reorienting my research: in the field of supercritical fluids but on a more applied subject, the precipitation and encapsulation of nanoparticles. This new stage starts with the study of nanoparticle precipitation of pure compounds, and then it is implemented with the encapsulation and/or coprecipitation of the nanoparticles with biopolymers. In the last years, I have evolved towards obtaining nanoparticles from natural matrix extracts to obtain compounds with bioactive properties and their deposition in solid porous matrices. Working with polymers for encapsulation and with porous matrices for impregnation has made possible to develop the current line of research: to create our own porous matrices of biocompatible polymers by means of foaming and their impregnation with bioactive substances, always using supercritical technology. |
