Facile synthesis of novel carbon-dots/hemin nanoplatforms for synergistic photo-thermal and photo-dynamic therapies
Abstract
Due to the traditional therapies of cancer inducing huge pains to patients, the non-invasive photo-guided therapies are attracting massive attentions of researchers. Herein, the intelligent-designed carbon-dots/hemin nanoplatforms (HCDs NPs) were developed, owning high-authority photo-therapy for cancer. The fluorescence resonance energy transfer (FRET) effect enhanced the photo-thermal ability of HCDs NPs, endowing the synthesized nanoplatforms with photo-dynamic property simultaneously. Therefore, the obtained HCDs NPs could achieve synergetic photo-thermal and photo-dynamic therapies for cancer. Basing on the experimental results, the prepared HCDs NPs could induce the temperature enhancement high to ca 26 °C under laser irradiation, also with the outstanding photo-dynamic efficacy. More than 90% of cancer cells die after 10 min laser treatment. Thus, the dual-modal photo-therapeutic HCDs NPs are promising and excellent nanomaterials for potential application in synergistic cancer therapy.
