Figure 2: (A) Daily elution of FITC-albumin from microparticles synthesized with low and high molecular weight (LMW and HMW, respectively) PLGA. Increase in ultrasonication power resulted in lower drug elution rates for LMW particles. (B) Cumulative elution of FITC-albumin from microparticles synthesized with low and high (LMW and HMW, respectively) molecular weight PLGA.
