aMolecular masses were measured by GPC, PDI is the polydispersity index, given by Mw/Mn; bspecific optical rotation (c = 1, in H2O, at 25°C); chydrodynamic particle diameter, measured by DLS, as described in the Materials and methods section; dparticle density was measured as described in the Materials and methods section; fP(EF-PLLA), PLLA 10% of the total monomer weight.
