Abstract: Nanomaterials are one of the important development directions in nano-science and technology. The structure of nanomaterials has endowed it unique optical properties,the nanometer size facilitates its targeting to tumor tissue via EPR effect or surface modification,and some nanomaterials can absorb the energy of an external light source and convert it into heat energy. Therefore,nanomaterials are widely applied in optical sensors,bioimaging,drug-targeted delivery,and tumor photothermal therapy. This review mainly describes the excellent properties of optical nanomaterials and photothermal nanomaterials,and illuminates their applications in the above fields. Finally,the future development trend of nanomaterials is prospected.
