Abstract | PURPOSE: To establish a NIR (near infrared)-/pH-responsive and sustained-release tumor-targeting drug delivery system (SWNT-PEI/DOX/NGR). METHODS: RESULTS: The SWNT-PEI/DOX/NGR delivery system has significantly sustained-release effect and the slow release of DOX in normal tissues contribute to reduced systemic toxicity, while under 808 nm NIR laser irradiation or under lower pH environment the release of DOX can be accelerated. CONCLUSIONS: Due to hyperthermia sensitizer effect of DOX, chemo-photothermal exemplified by SWNT-PEI/DOX/NGR tumor-targeting delivery system is a promising approach to anticancer therapy in vivo or in vitro.
