Microfluidic Device for Forming Monodisperse Lipoplexes

Tech ID: 18776 / UC Case 2006-644-0


The determinant factor for the successful applications of delivering drugs is to develop a non-viral and efficient carrier. Cationic lipid based liposomal carriers are the most attractive non-viral solution. Advantages of liposomal vectors include safety, lack of immunogenicity, ability to package large DNA molecules and ease of preparation. However, the conventional processes for catatonic lipids and DNA complex formulation are normally irreproducible.

Technology Description

A microfluidic device using a picoliter micro-reactor and incubator (PMRI) system has been developed to improve the generation of cationic lipids and DNA. This system decreases the range of size distributions and improves the gene transformation rate. The device may be used for in vitro and in vivo gene therapy and these lipid-gene complexes may be used in gene therapy applications.
