Nanomedicine-based photothermal therapy (PTT) has been considered as an excellent alternative for treatment of tumor tissue due to its high therapeutic efficiency and controllable range. However, the overexpression of heat shock proteins (HSPs) during PTT and the hypoxic properties of the tumor microenvironment can lead to intracellular thermal resistance and reduce its effectiveness. Reactive oxygen species (ROS), followed by the application of chemodynamic therapy (CDT) and photodynamic therapy (PDT), can eliminate HSPs and overcome thermal resistance. High concentration HO was used to catalyze oxygen production in the tumor microenvironment to improve the anaerobic state. Therefore, we present a multifunctional nanocarrier system driving chemodynamic-photodynamic-photothermal synergistic therapy self-supplied hydrogen peroxide and relieved hypoxia for prostate tumor treatment.

Micro/Nanorobots(MNRs)integrated with phototherapy represent an emerging approach to cancer treatment and hold significant potential for addressing bacterial infections, neurological disorders, cardiovascular diseases, and related conditions. By leveraging micro/nanoscale motor systems in conjunction with phototherapy, these robots enable real-time guidance and monitoring of therapeutic processes, improving drug delivery precision and efficiency. This integration not only enhances the effectiveness of phototherapy but also minimizes damage to surrounding healthy tissues.

A lysosome-targeting chimera (LYTAC) offers a novel strategy for degrading extracellular proteins previously considered to be undruggable by hijacking the lysosomal degradation system. However, clinical use of LYTAC has been limited due to the potential for uncontrolled degradation and systemic toxicity. Based on our previously developed genetically encoded TfR-LYTAC, here, we introduce a photothermal-inducible switch in the engineered bacterium to enable spatiotemporal expression of TfR-LYTAC.

The development of multiple fluorescent agents has contributed to cancer diagnosis and therapy. Near-infrared (NIR) dyes have already been well studied and displayed significant potential in cancer bioimaging and therapy due to their unique characteristics. In the present literature, we illustrated the updated NIR classification and characteristics as well as their applications in (pre-) clinical cancer imaging and treatment.

Head and neck cancer (HNC) includes various malignancies and represents the seventh most common cancer worldwide. The early diagnosis of HNC results in a 70-90% five-year survival rate, which declines with locally advanced stages of disease. Current care employs a multimodal strategy encompassing surgery, radiation therapy (RT), chemotherapy, and immunotherapy, while treatment options vary according to the stage, tumor features, and patient characteristics.
