Abstract:
Objective :To explore the application of ZnxNi1－xS@ DOX nanostructures in combined photothermal- chemotherapy treatment of tumors，and to provide new ideas for the study of tumor treatment methods．
Methods:The morphology and elementary composition of ZnxNi1－xS nanostructures were characterized by scanning emission e- lectron microscopy and other methods．The photothermal properties of ZnxNi1－xS nanostructures were explored by infrared thermal camera．The release of DOX under different temperature and pH was investigated by fluorescence spectrophotometer．The biosafety of ZnxNi1－xS nanostructures and the in vitro antitumor properties of ZnxNi1－xS@ DOX nanostructures were investigated by MTT assay.
Results :The as-prepared ZnxNi1－xS nanostructure had good dispersion and uniform size．The ZnxNi1－xS nanostructures had good photothermal effect．The drug release behavior showed temperature and pH responsiveness．The MTT assay showed that ZnxNi1－xS nanostructures were nontoxic to normal cells．ZnxNi1－xS@ DOX nanostructures could significantly inhibit the growth of tumor cells under near-infra- red illumination．
Conclusion :The as-prepared ZnxNi1－xS nanostructure has good biocompatibility，on the basis of which the ZnxNi1－xS@ DOX nanostructures achieve good antitumor performance，which can be used for combined photothermal-chemotherapy treatment of tumors.
