The development of liposomes as a drug delivery system has fluctuated since its introduction in the late 1960's by A.D. Bangham. While academic research of liposomes as a model membrane system has always flourished, as the exponential growth of papers can testify, the application of these findings to medically useful products has gone through several crises. Following the original optimism in the 70's and early 80's, a period of severe skepticism ensued at the end of the 80's and beginning of the 90's, culminating in a moderate but real optimism in the mid 90's, as a result of a successful lau

Gene transfer within humans has been an obstacle until about 10 years ago. At that time, it was found that viral vectors were effective carriers of ""healthy genes"" into patients' cells. The problem, however, was that viral vectors proved unnecessarily harmful to humans: subjects experienced inflammatory activity and negative immunological responses to the genes. Viral vectors were also unable to meet the needs of the pharmaceutical community: they were not reproducible in large-scale proportions in cost-effective ways.
