Conjugates of formula I, below, are useful in biomedicinal applications such as delivery of drugs or labeling moieties or as components of liposomes or micelles. In formula I, A is a hydrophilic polymer, each of L and L' is independently a linker group, B is a lipid moiety; and Z is a diagnostic ligand, a biologically relevant ligand, or a reactive linking moiety, which is generally linked to the phosphorus atom of the conjugate via a nitrogen, oxygen or sulfur atom in Z.
