γ‐Butyrolactone Copolymerization with the Well‐Documented Polymer Drug Carrier Poly(ethylene oxide)‐ block ‐poly(ε‐caprolactone) to Fine‐Tune Its Biorelevant Properties

Polymeric drug carriers exhibit excellent properties that advance drug delivery systems. In particular, carriers based on poly(ethylene oxide)‐ block ‐poly(ε‐caprolactone) are very useful in pharmacokinetics. In addition to their proven biocompatibility, there are several requirements for the efficacy of the polymeric drug carriers after internalization, e.g., nanoparticle behavior, cellular uptake, the rate of degradation, and cellular...
