Non-plasmonic NIR-Activated Photothermal Agents for Photothermal Therapy

2020
Photothermal therapies rely on various types of optically active nanomaterials, such as carbon, silicon, titanium dioxide, iron-based, polymeric, and rare earth-doped nanomaterials, which are aiming to convert light into heat. However, lack of clear guidelines and standardized approaches to determine their photothermal properties hinders quantitative ...

Self‐Regenerating Photothermal Agents for Tandem Photothermal and Thermodynamic Tumor Therapy

Small Methods
AbstractSmall molecule‐based photothermal agents (PTAs) hold promising future for photothermal therapy; however, unexpected inactivation exerts negative impacts on their application clinically. Herein, a self‐regenerating PTA strategy is proposed by integrating 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) radical cation (ABTS•+) with a ...
