    Abstract Photocatalytic synthesis of hydrogen peroxide offers an effective solution to the energy crisis. The design and development of high-activity and low-cost photocatalysts are crucial for H2O2 production. In this work, Zn0.4Cd0.6S with abundant S vacancies (SV-ZCS) is developed for H2O2 photosynthesis under 405 nm LED illumination without additional cocatalysts. The S vacancies serve as photo-generated electron trap centers, effectively extending the lifetimes of photogenerated carriers and promoting the separation of photoelectric carriers. Additionally, SV-ZCS is endowed with enhanced light capture capability, enhancing the overall photocatalytic activity for H2O2 production. The results were in line with expectations, the SV-ZCS samples More >

    Abstract Background: Phototherapies based on sunlight, infrared, ultraviolet, visible, and laser-based treatments present advantages like high curative effects, small invasion, and negligible adverse reactions in cancer treatment. We aimed to explore the potential therapeutic effects of blue light emitting diode (LED) in human hepatoma cells and decipher the underlying cellular and molecular mechanisms. Methods: Wound healing and transwell assays were employed to probe the inhibition of the invasion and migration of hepatocellular carcinoma cells in the presence of blue LED. The sphere-forming test was used to evaluate the effect of LED blue light irradiation on cancer… More > Graphic Abstract
