Part of the Fundamental Biomedical Technologies book series (FBMT, volume 4)

Liposomes, spontaneously forming lipid nanoparticles, have long been recognized to have great potential as carriers for diagnostic and therapeutic agents since their initial discovery more than 40 years ago (Gregoriadis and Ryman 1971; Bangham 1993). In the last 30 years, remarkable progress in liposome technology has been accomplished in the following areas (1) methods of large-scale manufacture, (2) methods of stably encapsulating sufficient quantities of therapeutic agents within the liposomes, (3) methods of producing homogeneously sized liposomes, (4) effective methods of noninvasively tracking the distribution of liposomes in the body, and (5) development of methodology to prolong the circulation time of liposomes in the blood (Allen et al. 1991; Phillips et al. 1999; Torchilin and Papisov 1994).
