Microspheres were formed from blends of the biodegradable polymer poly(DL-lactic-co-glycolic acid) (PLGA) together with poly(epsilon-CBZ-L-lysine) (PCBZL) by a double-emulsification/solvent evaporation technique. The size of the microspheres formed by this method was dependent both on the total concentration of the polymers
