The following Formula I conjugates are useful in biomedical applications, for example in drug delivery or labeling moieties or as elements 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, Z is a diagnostic ligand, a biologically relevant ligand, Or a reactive binding moiety, which is generally attached to the phosphorus atom of the conjugate via a nitrogen, oxygen or sulfur atom in Z (FI). |
