Light stimulus responsive nanomedicine in the treatment of oral squamous cell carcinoma

Abstract

Light stimulus responsive therapies are based on a variety of low-toxic therapeutic agents and produce anti-tumor effects only under external light stimulation, thus greatly reducing system toxicity and improving the specificity of treatment. Moreover, light stimulus responsive drug delivery system (DDS) can combine various theranostics molecules to exert synergistic therapeutic effects of various treatments, which has played an important role in cancer treatment. In this review, we introduced the light stimulus responsive cancer therapies including photodynamic therapy (PDT), photothermal therapy (PTT) and light-triggered DDS applied in the treatment of OSCC, described considerable photosensitizers (PSs) and nanomaterials used for oral cancers, which will hope to better the clinic outcome of OSCC patients.
