Summary: Silver particles have been frequently coated on the surface of substrates with the assistance of polydopamine due to their important catalytic and antibacterial properties. However, the polydopamine layer was not compact and the resulted particles on the substrates were easy to leak during the application process, especially in the aqueous environment. For mediating this, we coated Ag particles on the surface of polypropylene (PP) nonwoven fabric by codeposition of catechol and polyethyleneimine, with subsequent crosslinking by glutaraldehyde. The Ag@PP nonwoven fabric exhibited efficient degradation of 4-nitrophenol and excellent antibacterial activity against E. coli.

Summary: In this study, Au nanoparticles were synthesized and encapsulated in hollow porous silica nanospheres (Au@HPSNs). The Au@HPSNs consisted of extremely small Au nanoclusters (-1.3 nm) enclosed in high specific surface area (-800 m2/g) HPSNs. The formation of PEI-PAA@SiO2 core-shell structures was achieved by using electrostatic attraction between poly(acrylic acid) (PAA) anions and protonated poly(ethylenimine) (PEI) in an ethanol-water system. The Au@HPSNs were obtained by soaking PEI-PAA@SiO2 in HAuCl4 solution and subsequent calcination. The Au@HPSNs exhibited highly efficient catalytic activity for 4-nitrophenol (4-NP) reduction with NaBH4, surpassing the current record for heterogeneous Au-based catalysts in 4-NP reduction. The enhanced performance of Au@HPSNs can be attributed to the ultra-fine Au nanoclusters and the small mass transfer hindrance with high specific surface area hollow porous silica.

Summary: This study demonstrates a novel biomineralization-inspired strategy for the synthesis of a fructose incorporated manganese phosphate (Fru-MnP) nanoplatform for targeted therapy, drug-free therapy, and MRI imaging of osteosarcoma. The Fru-MnP nanoplatform produces reactive oxygen species (ROS) through the Mn2+-driven Fenton reaction within osteosarcoma cells, leading to caspase-mediated apoptosis and efficient cancer cell killing. Additionally, it serves as an effective tumor-specific MRI contrast agent, allowing for MRI-monitored chemodynamic therapy.

Summary: The tumor microenvironment (TME) is a complex environment characterized by low pH values, high redox status, and hypoxia, which plays a significant role in the genesis, development, and metastasis of tumors. Immunosuppressive cells infiltrate in the TME, leading to the failure of immunotherapy. Therefore, the development of TME-responsive nanoplatforms is essential for enhancing cancer therapeutics. Metal-phenolic networks (MPNs)-based nanosystems, self-assembled via coordination of phenolic materials and metal ions, have emerged as excellent TME theranostic platforms.

Summary: Radiotherapy is effective in immunoactivation but lacks the ability to turn tumor into an immunogenetic center. This study introduces an epigenetic strategy to induce cancer pyroptosis in radiotherapy by constructing a nanocoordinator (PWE) that comprises a polyphenolic DNA methyltransferase inhibitor, a high-Z radiosensitizer, and a polyphenol-modified block copolymer. PWE recovers GSDME expression and cleaves it into fragmented GSDME N-terminal, amplifying the immunological effects of traditional radiotherapy and decreasing regulatory T cells upregulated by radiotherapy.

Summary: Intratumoral CD8(+) T cells play a crucial role in cancer immunotherapy, but the immunosuppressive tumor microenvironment (TME) limits their function and infiltration. Drug repurposing has identified existing drugs as immune modulators to improve TME immunosuppression and reactivate T-cell-mediated antitumor immunity. However, the suboptimal availability of these drugs in tumors hampers their full immunomodulatory potential. Self-degradable PMI nanogels carrying repurposed immune modulators (imiquimod and metformin) are developed for TME-responsive drug release. They remodel the TME by promoting dendritic cell maturation, repolarizing M2-like tumor-associated macrophages, and downregulating PD-L1 expression. Ultimately, the PMI nanogels reshape the immunosuppressive TME and efficiently enhance CD8(+) T cell infiltration and activation. These results suggest that PMI nanogels could be an effective combination drug with anti-PD-1 antibodies to enhance antitumor immune responses.

Summary: The interaction between PD-1 and PD-L1 in malignant melanoma cells promotes tumorigenesis, angiogenesis, and radio-resistance through mTOR hyperactivation. Blocking PD-L1 and mTOR signaling concurrently, along with radiotherapy, can alleviate tumor burden. A three-pronged platinum@polymer-catechol nanobraker, delivering mTOR inhibitor TAK228 and anti-PD-L1 antibody, effectively inhibits melanoma-PD-1-driven aggression and enhances melanoma eradication, while also amplifying the efficacy of radiotherapy.

Summary: Cancer cells compete with tumor-infiltrating T lymphocytes (TILs) for glucose uptake, which alters the tumor microenvironment (TME) and impairs CD8(+) TIL effector function. Inhibiting aerobic glycolysis in cancer cells and inducing mitochondrial dysfunction can reprogram TME and enhance CD8(+) T cell activation. A sono-metabolic cancer therapy using Hyaluronic Acid (HA)-modified metal-phenolic nanomedicine (HPP-Ca@GSK) is proposed to achieve these goals. In vitro and in vivo studies show that HPP-Ca@GSK-based sono-metabolic treatment exhibits significant anticancer activity and can be further enhanced by destabilizing T-reg cells with anticytotoxic T lymphocyte-associated protein-4 antibodies. These findings provide a metabolic intervention strategy for cancer immunotherapy.

It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
