Researchers from Jianghan University have developed a biocompatible zinc–oxygen (Zn–O₂) battery that operates stably inside the body, addressing corrosion and biosafety issues that limit traditional implantable power sources. The device uses a composite gel electrolyte to resist oxygen and moisture infiltration while maintaining excellent biocompatibility. When implanted in rats, it delivered stable voltage output sufficient to power biosensors. This work offers a safe and durable energy platform for future implantable medical devices and bioelectronic therapies.

This work presents efficient short-wave infrared (SWIR)–emitting InP quantum dots (QDs) synthesized through controlled core nucleation and copper doping, achieving a high photoluminescence quantum yield (PLQY) of 66% at 960 nm. When integrated into a liquid waveguide luminescent solar concentrator (LSC), these QDs enabled an optical efficiency of 7.36% through optimized light management and spectral alignment with the responsivity peak of silicon solar cells, demonstrating the potential of InP QDs as a sustainable and high-performance material platform for SWIR optoelectronics.

In response to dysregulated cholesterol metabolism in cancer, researchers have developed a nanozyme (AVA-COD@Fe) that depletes tumors of cholesterol and promotes ferroptosis. This strategy simultaneously inhibits cancer growth and metastasis while activating a robust antitumor immune response, which is further enhanced by anti-PD-L1 therapy to effectively combat both primary and metastatic tumors.

The rising global burden of cancer necessitates innovative therapeutic strategies, with immunotherapy demonstrating remarkable potential. However, its clinical efficacy remains limited by low response rates and non-specific (off-target) delivery. Authors in this review highlights natural polymer-based hydrogels as emerging delivery platforms engineered to enhance the efficacy of cancer immunotherapy. These hydrogels exploit the biocompatibility and biodegradability of natural polymers, employing chemical or physical crosslinking to encapsulate and deliver immunotherapeutic agents. The versatility of these hydrogels is discussed in the context of oral, sprayable, injectable, and implantable formulations, adaptable to specific tumor sites. Their responsiveness to stimuli such as pH, temperature, and enzymatic activity enables controlled and sustained release of immunotherapeutic agents, including checkpoint inhibitors, cytokines, and Toll-like receptor agonists. These hydrogels can also modulate the tumor microenvironment by regulating pH, oxygen levels, and immune cell infiltration, thereby enhancing therapeutic efficacy. Moreover, immunotherapeutic hydrogels can act synergistically with chemotherapy, radiotherapy, and phototherapies to enhance antitumor immune responses. Despite their potential, challenges such as degradation kinetics, bioactivity retention, and regulatory hurdles must be addressed to ensure successful clinical translation. This review provides insights into the rational design, development and application of stimuli-responsive hydrogels as next-generation platforms for effective cancer immunotherapy.

Electromagnetic waves are extensively utilized in many fields such as communication and medicine. Excessive electromagnetic waves will cause electromagnetic pollution. Electromagnetic pollution may lead to electromagnetic interference (EMI), which will interfere sensitive electronic devices. Furthermore, electromagnetic pollution is harmful to human health and may potentially cause information leakage. The development of lightweight and flexible EMI shielding materials with high mechanical strength and excellent flame retardant properties is currently a hot and difficult research topic.
