Summary: Photothermal therapy is a promising approach for cancer treatment, and the Injectable Optical System (IOS) technique enables the guidance of near-infrared light into deep tissues for effective treatment. IOS not only transports light energy into deeper tissues, but also facilitates drug delivery and synchronous sampling of diseased tissues during treatment.

Summary: A multi-dynamically crosslinked nanocomposite hydrogel was prepared in this study using dextran modified with aldehyde groups and phenylboronic acid esters, carboxymethyl chitosan, polyaniline grafted chitosan oligosaccharide, and Epigallocatechin Gallate/Ca2+ modified melanin-like nanoparticles. The hydrogel showed good photothermal conversion properties, antioxidant activity, and mechanical properties. It could also record respiratory and heart rate signals in real time and distinguish them accurately using a convolutional neural network algorithm. This multifunctional nanocomposite hydrogel provides a new strategy for promoting chronic wound healing and effective health monitoring.

Summary: The study demonstrated the efficient phototherapeutic effect on deep-sited tumors for the first time by utilizing tissue optical clearing (TOC) technique. By optimizing a hybrid TOC agent and using gold nanocages as a nano-platform model, a synergistic antitumor efficacy of photothermal therapy (PTT) and chemotherapy was achieved, improving the clinical application potential of various phototherapies on deep-sited tumors.

Summary: The development of hydrogel dressings with injectability, adhesion, antibacterial properties, and wound healing promotion is urgently needed. The design of multifunctional injectable hydrogels based on Ag-doped Mo2C-derived polyoxometalate (AgPOM) nanoparticles, urea, gelatin, and tea polyphenols (TPs) has been presented for antibacterial and wound healing acceleration. The hydrogel exhibits excellent tissue adhesion after injection due to the in situ formation triggered by recombination of TPs and gelatin chains. AgPOM in the hydrogel acts as an antimicrobial agent by generating singlet oxygen and sterilizing under near-infrared light. In vitro studies demonstrate high bactericidal ability against drug-resistant Staphylococcus aureus and facilitate wound healing through synergistic photothermal/chemodynamic therapy. Therefore, the injectable hydrogel with AgPOM offers a novel therapeutic agent for drug-resistant bacteria-infected wounds and wound healing promotion.

Summary: A methacrylic gelatin/oxidized dextran/montmorillonite-strontium/polypyrrole (GOMP) hydrogel with a dual network structure was synthesized. The hydrogel demonstrated sustained release of doxorubicin (DOX) due to the network structure. The inclusion of polypyrrole provided conductivity and photo-thermal conversion capacity to the hydrogel, resulting in a high photothermal conversion efficiency of 31.61% under 808 nm laser radiation. The GOMP hydrogel exhibited good swelling properties in solvents and showed excellent biocompatibility and biodegradability in vitro and in vivo. Furthermore, the in vitro and in vivo experiments demonstrated synergistic effects of DOX-loaded GOMP hydrogel on tumor cell apoptosis through chemotherapy and photothermal therapy, while the inclusion of montmorillonite-strontium (MMT-Sr) improved the mechanical properties and promoted bone regeneration. The multifunctional GOMP hydrogel shows great potential for osteosarcoma treatment.

Summary: Phototherapeutic agent-based phototherapies have been proven to be safe for the treatment of malignant tumors. The main modalities include photothermal therapy and photodynamic therapy. However, the phototoxicity of these therapies limits their clinical application. To improve therapeutic performance and minimize side effects, researchers have focused on developing hydrogel-based phototherapy.

Summary: In this study, a multifunctional nanozyme hydrogel based on Cu-doped polypyrrole (CuP) was developed to enhance the anticancer effect of radiotherapy. The CuP-based hydrogel released CuP nanozyme under laser irradiation, providing photothermal therapy and inhibiting DNA damage repair caused by radiotherapy. CuP also depleted intracellular GSH and generated center dot OH to kill tumor cells, thus enhancing the capability of low-dose radiotherapy to inhibit tumor growth.

Summary: Monitoring and modulating the activity of the deep and intermediate layers of the superior colliculus can effectively suppress absence seizures in the WAG/Rij genetic model. Continuous optogenetic stimulation of the DLSC significantly reduces seizure frequency, and closed-loop neuromodulation is effective in both males and females at different frequencies.
