Visions but Not False Promises Should Be Funded

Abstract

Efforts to develop cell-specific drug-delivery systems have been under way for decades but have not as yet generated effective and reliable therapeutic products. The effect of repeatedly unfulfilled promises is starting to cause a decrease in funding support for research and development in this area. In this commentary, principle flaws in the current approaches are listed and discussed. Further, the manner in which approaches and paradigms for further development should change is suggested.
