Strategies for efficient photothermal therapy at mild temperatures: Progresses and challenges

Photothermal therapy (PTT), typically ablates tumors via hyperthermia generated from photothermal agents (PTAs) under laser irradiation, has attracted great attentions in the past decades. Unfortunately, longstanding, frequent and high-power density laser irradiations are needed to maintain the hyperthermal status (>50 °C) for efficient therapy, which will damage the skin and nearby healthy tissues. Suppressing cancer cells with a mild...
