Abstract
The first part explains the discovery, and means to employ the discovery that whole, intact vesicles and liposomes are not the sole means of burden (drug) delivery by targeting molecules. The second part teaches the discovery of reverse loading of vesicles and liposomes to obtain fully functional core volume load of a useful burden without the trauma degradation of the active burden material, and with greatly extended shelf life.
