Abstract
A method of forming an analyte-functionalized liposome for use in immunoassay techniques employs a phosphotriester intermediate of a phospholipid derivatized with the desired analyte in a process of forming a liposome which is functionalized on its outer surface with the analyte and which carries an enzyme marker. The method is also used to functionalize the liposome with a ligand which acts as a leash between the analyte and the liposome. Liposomes produced by the method include penicillin-G-functionalized liposome.
