Double Bagging at the Nanoscale

In the drug delivery field, lipid-based carriers could be used to target the delivery of chemotherapy agents. However, the major limitation has been the premature release of the drugs due to enzymatic degradation of the lipid membranes. Dr. Zasadzinski's group has developed a fix to this problem by entrapping both the lipid carrier and the drug within a second bilayer membrane--double bagging, but at the nanoscale. They call this a vesosome. The double bagging provides a 100-fold decrease in the release rate of important chemotherapy and antibiotic drugs in the blood.

------PRESENTER------

Dr. Joe Zasadzinski
Professor of Chemical Engineering and Materials, UCSB

Dr. Joe Zasadzinski has been a professor of Chemical Engineering and Materials at UCSB for 20 years. His BS in chemical engineering is from the California Institute of Technology in 1980, and his Ph.D was from the University of Minnesota in 1985. He won the 2004 American Chemical Society Award in Colloid Science and is a fellow of the American Association for the Advancement of Science.
