Combined Concurrent Photodynamic and Gold Nanoshell Loaded Macrophage-Mediated Photothermal Therapies: An In Vitro Study on Squamous Cell Head and Neck Carcinoma

摘要

Background and ObjectiveTreatment modalities, such as hyperthermia and photodynamic therapy (PDT) have been used in the treatment of a variety of head and neck squamous cell carcinoma (HNSCC), either alone or as an adjuvant therapy. Macrophages loaded with gold nanoshells, which convert near-infrared light to heat, can be used as transport vectors for photothermal hyperthermia of tumors. The purpose of this study was to investigate the effects of combined macrophage mediated photothermal therapy (PTT) and PDT on HNSCC cells.
