Liposomes as “targeted” drug carriers: A physical chemical perspective

Over the last several years liposomes have increasingly caught the imagination of physical chemists, biologists, and medical scientists. In the lastmentioned context, they are being studied as carriers for selective drug delivery. In this lecture I will first give a brief overview of the possibilities and problems of liposomal carriers. Then I will discuss several instances in which physical chemical ideas are contributing directly to the medical objectives. Finally, I will indicate remaining problem areas in need of additional physical chemical insight.
