  1. aMePEG-5 k: MePEG-NHS, M.W. = 5000 g/mol from the manufacturer. M.W. estimation of block copolymer using 1H-NMR spectroscopy was calculated based on MePEG-5 k
  2. bM.W. of PLA was calculated from following the equation M.W. of LEse copolymer – M.W. of MePEG 5 k
  3. Mn number-average M.W, Mw weight average M.W, PD polydispersity
