Summary: This study introduces a promising strategy for cancer immunotherapy, micro-LED guided PDT with mild visible light. The implantable micro-scale light-emitting diode device enables the on-demand activation of photosensitizers deep in the body, enhancing antitumor immunity. The results show that micro-LED guided PDT using mild visible light can promote immunogenic cell death in tumor cells, improve therapeutic efficacy, and boost antitumor immunity. Combining micro-LED guided PDT with immune checkpoint blockade leads to complete tumor regression and establishes systemic immunological memory to prevent tumor recurrence.

Summary: The development of fabrication technologies and new materials has significantly improved the performance of electronic devices while reducing their overall size. However, micro/nano-size electronic devices have faced issues related to isolated heat generation in concentrated areas, especially in bio-integrated devices. To address this problem, a microscale light emitting diode (mu LED)-based neural probe with an injectable heat dissipation guide made of boron nitride (BN) nanomaterials is introduced. This heat dissipation guide effectively dissipates heat, leading to improved optical output performance of mu LEDs and enhanced lighting transmission through brain tissue without thermal damage. Additionally, it shows remarkable improvement in the therapeutic effect of photodynamic therapy in mouse cancer cells.

Summary: Conductive textiles can be created by coating fabric with liquid metal particles, which provides possibilities for human-machine interfaces and wearable electronics. In this method, the fabric is dipped into a suspension of liquid metal particles at room temperature. The coated fabric remains electrically insulating due to the native oxide on the particles, but can become conductive by compressing it to rupture the oxide and allow particle percolation. Conductive circuits can be patterned on the textile by compressing it with a patterned mold. The electrical conductivity of these circuits can be improved by increasing the particle coating. The LM-coated textiles also possess antimicrobial protection against Pseudomonas aeruginosa and Staphylococcus aureus, and the conductive patterns autonomously heal when cut.
