The application of the biphasic release profile furnished by electrospun polyblend nanofibers for local cancer treatment was investigated. By adjusting the weight ratio of the hydrophilic polymer (poly(ethylene oxide), PEO) and hydrophobic polymer (poly(L-lactide), PLA), PEO10-PLA90 fibers with typical biphasic release kinetics were successfully prepared. Due to their unique release profile, PEO10-PLA90 fibers can quickly access the tumor site in vivo at a high drug content within 1 h and keep at a high level for longer than two weeks. In vivo antitumor and safety studies demonstrated that PEO10-PLA90 fibers can achieve optimized local cancer treatment efficacy and avoid undesired adverse reactions. The biphasic drug release profile provided by the polyblend electrospun technology was proven to be a new conception for local chemotherapy.
