The problem of drug delivery has been of continuous research interest to the biomedical scientific community. The basic problem of drug delivery is to facilitate the transport of medication via the bloodstream to the target organs. This process can be significantly hampered by the hydrophobic nature of most medications. Pharmaceutical compounds and in particular chemotherapeutics (which are a specific area of research at the Cornell Medical Center and the Sloan-Kettering Institute) tend to be extremely hydrophobic. Blood is a hydrophilic environment, so the hydrophobic drugs simply cannot dissolve in the bloodstream. As a result they cannot be transported successfully to the target tissues. For example, Sloan-Kettering possesses compounds that kill cancer cells 100ln vitro, yet those same compounds are virtually inactive in vivo because of their insolubility in the blood. It was our purpose, therefore, to develop an appropriate and successful drug delivery system.
