Glutathione-responsive biodegradable nanohybrid for cancer photoacoustic imaging and gas-assisted photothermal therapy

Photothermal therapy (PTT), particularly in the near-infrared-II (NIR-II) range, has attracted widespread attention over the past years. However, the accompanied inflammatory responses can result in undesirable side effects and contribute to treatment ineffectiveness. Herein, we introduced a novel biodegradable nanoplatform (CuS/HMON-PEG) capable of PTT and hydrogen sulfide (H
