Prodution and characterization of nano- and microparticellar "system for biopharmaceutical applications on a Lab-on-a-chip based microelectronic technology". Production and characterization of polymeric microspheres. The project is devoted to the selection of the particles that optimally fit to “Lab-on-a-chip” biopharmaceutical applications. Polymeric microspheres will be produced and characterised by different experimental approaches including solvent evaporation, spray drying and thermal gelation.
