Production and phisical-chemical analysis of cationics liposomes and STEALTH® types, obtained from microfluidic tecnology for gene therapy application

Resumo

The research was focused on the production of lipid based vectors for gene therapy by microfluidic devices, particularly carionic liposomes (CL), and their complexation with plasmidic DNA (pDNA). Two types of microfluidic devices were proposed to achieve the goals, a diffusion based microfluidic device (D-MD) and a caotic advection based microfluidic device (CA-MD). The research showed that the CA-MD has a better productivity of CL while maintaining good properties. In the complexation studies, the D-MD was capable of make the complexes of genetic materials and liposomes (Lipoplexes).
