The as-prepared HCPT/Ce6 NRs possessed a relatively uniform size of around 165 nm and zeta potential of about −29 mV, together with good stability in aqueous solution and freeze-dried state. In addition, both the extra- and intracellular reactive oxygen species (ROS) generation capacity of the NRs under laser irradiation was significantly enhanced compared with Ce6 injections. Moreover, the dual-functional HCPT/Ce6 NRs exhibited a substantial in vitro/in vivo synergistic antitumor efficacy under laser irradiation due to the integration of the two therapeutic modalities into one drug delivery system. Besides, no obvious hepatic or renal toxicity was observed in the NRs treatment groups.Conclusion: Taken together, HCPT/Ce6 NRs demonstrated a powerful efficacy in chemo-photodynamic therapy for breast cancer. Therefore, the carrier-free dual-functional NRs prepared in a facile and effective strategy might give inspiration for the development of combined antitumor therapy.Keywords: carrier-free, self-assembly, chemo-photodynamic, dual-functional nanorods, combined antitumor therapy, synergistic antitumor efficacyZhao YZhao YMa QSun BWang QDing ZZhang HChu XLiu MWang ZHan JDove Medical Pressarticlecarrier-freeself-assemblychemo-photodynamicdual-functional nanorodscombined antitumor therapysynergistic antitumor efficacyMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 8665-8683 (2019) |
