Summary: Photoimmunotherapy is a novel targeted therapeutic strategy for highly malignant triple-negative breast cancer. However, its therapeutic effect is restricted by limited tissue penetration of light and complex immunosuppressive microenvironment. A new mace-like plasmonic Au-Pd heterostructures have been developed to enhance the outcomes of photoimmunotherapy. These structures exhibit strong photothermal and photodynamic effects, triggering immunogenic cell death and stimulating immune response. This study integrates nanotopology and plasmonic performance for the treatment of TNBC through immunotherapy.

Summary: Osteomyelitis is a refractory disease in orthopedics caused by infection with pathogenic microorganisms. Antibacterial therapy, in addition to surgical debridement, is currently the main approach for treating osteomyelitis. However, traditional antibiotics are facing bacterial resistance, prompting the development of advanced antibacterial agents. This review discusses the main targets and mechanisms of antibacterial agents for osteomyelitis treatment, as well as their potential clinical applications.

Summary: Microwave (MV)-trigged dynamic therapy using MV-responsive materials shows promise for treating deep infection diseases, including life-threatening osteomyelitis, that are not effectively treated by antibiotics. Surface states of materials play a key role in the generation of free charges and the MV dynamic effects. A new MV responsive system, consisting of a 2D metal-organic framework (2D MOF) on oxidized carbon nanotube (CNT), is developed, which exhibits highly effective antimicrobial activity and eradicates Staphylococcus aureus infected rabbit tibia osteomyelitis under MV irradiation. This study represents a major advancement in antibiotic-free MV therapy for deep tissue bacterial infection.

Summary: In this study, a rapid and noninvasive therapeutic strategy was developed using Prussian blue as a microwave-responsive material to effectively treat bacteria-induced osteomyelitis. The released Fe2+ and Fe3+ from PB could easily penetrate bacterial membrane by microwave, react with H2O2 and GSH inside bacteria, leading to the final death of the bacteria due to the synergistic action of microwave, microwave thermal effect and Fe2+/Fe3+ induced Fenton reaction/GSH consumption. This study provides novel insight for designing remote and noninvasive antibacterial systems for treating deep bacteria-infected diseases.

Summary: MW-responsive engineered pseudo-macrophages (M-Fe3O4/Au NPs) are able to clear Staphylococcus aureus infections, induce M2 polarization of macrophages, and enhance osteogenic differentiation of MSCs under MW irradiation. Fe3O4/Au NPs generate reactive oxygen species and heat under MW irradiation, promoting the production of ROS and reducing inflammatory cytokines secretion in MSCs. The engineered pseudo-macrophages show promise for treating bacterial infections and promoting osteogenic differentiation in deep tissues under MW irradiation.
