Abstract (EN): Cisplatin has demonstrated extraordinary anticancer activity against a variety of solid tumors. However, its clinical efficacy is contrasted by its toxicity profile. Having in mind the need to reduce the toxicity, promote a sustained release and enhance the body-circulation time of cisplatin, herein novel nanocarriers consisting of core-shell silica-coated iron oxide nanoparticles functionalized with dicarboxylic acid groups were prepared and characterized. Cisplatin was conjugated with the functionalized nanoparticles by surface tethering. Controlled release of cisplatin was observed without burst effect and in a sustained profile for up to 3 days. In vitro studies showed cytotoxic and antiproliferative effects of the cisplatin nanoconjugates against a human pancreatic cancer cell line. Importantly, when compared with free cisplatin, nanoconjugates exhibited lower cytotoxic effects regarding nonmalignant human duct pancreatic cells.
