MAPLE deposition of PLGA:PEG films for controlled drug delivery: Influence of PEG molecular weight

► We obtained implants from indomethacin cores coated with PLGA:PEG films grown by MAPLE. ► The implants were studied in vitro, in media close to those encountered inside the body. ► The influence of the molecular weight of PEG (1450 Da versus 10 kDa) was investigated. ► PEG of high molecular weight enhanced the blood compatibility of the implants. ► PEG of high molecular weight increased the drug release rates from the implants.
