Targeted, biocompatible, and synergistic all in one systems should be designed to combat the heterogeneity of cancer. In this study, we constructed a dual function nanosystem, copper sulfide nanoplatform loaded with the chemotherapeutic drug docetaxel wrapped by a conjugated polymer-peptide for targeted chemo-phototherapy. The nanoconstruct has been successfully designed with a size of 186.1 +/- 5.2 nm, a polydispersity index of 0.18 +/- 0.01, and zeta potential of -16.4 +/- 0.1 mV. The enhanced uptake and near-infrared-responsive behavior of the nanosystem resulted in efficient drug release, photothermal ablation, effective cytotoxic activity, and potentiated reactive oxygen species generation. The induction of apoptoticmarkers, enhanced accumulation in the tumor site, and maximumtumor growth inhibitionwere seen during in vivo studies compared to non-targeted nanoformulations and free drug. Cumulatively, our results indicate that, with low systemic toxicity and better biocompatibility, this nanoconstruct could provide a promising strategy for treating prostate cancer.
