Polylactic acid (PLA) nanospheres coated with monomethoxypolyoxyethylene (MPOE) were prepared from amphiphilic diblock copolymers (MPOE-PLA) by an emulsion-evaporation procedure in the presence of sodium cholate as surfactant. Nanospheres with various concentrations of MPOE at their surface and vari
