Co-delivery strategy using multifunctional nanocarriers is an attractive option for the synergistic and enhanced effects in cancer treatment, but one system integrating multiple functions for controlled release at the target is still challenging. Herein, this study shows the synthesis and characterization of our stimulus-responsive co-delivery system for the controlled release into tumors, which is composed of polyethylenimine (PEI)-linked Pluronic F127 (PF127) and folic acid (FA), called PF127-PEI-FA. PF127-PEI-FA system facilitated drug loading and gene complex formation, and showed controlled release behaviors in response to hitting temperature to hyperthermia. PF127-PEI-FA system was demonstrated to be biocompatible and showed receptor-mediated gene delivery. The results of our multifunctional nanocarrier system that enabled co-delivery suggest a promising potential for controlled drug release at targeted areas. However, further in-depth studies on the use of therapeutic drugs and genes in multiple cell types and the animal response are required. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
