Nanobiohybrids for solar-driven methanogenesis present a promising solution to the global energy crisis. However, conventional semiconductor-based nanobiohybrids face challenges such as limited tunability and poor biocompatibility, leading to undesirable spontaneous electron and proton transfer that compromise their structural stability and CH4 selectivity. Herein, we introduced eutectic gallium-indium alloys (EGaIn), featuring a self-limiting surface oxide layer surrounding the liquid metal core after sonication, integrated with Methanosarcina barkeri (M.

Ammonia-oxidizing bacteria (AOB) sourced from an aerobic granular sludge (AGS) process were rapidly enriched by progressively increasing ammonia nitrogen (NH-N) loads, achieving a Nitrosomonas abundance of 20.7 % and a nitrite accumulation rate exceeding 80 %. Mycelial pellets formed by Cladosporium, isolated from the same AGS system, provided a porous surface structure for the immobilization of the enriched AOB, creating mycelial pellet/AOB composites.

Wound healing is a complex and dynamic process often accompanied by bacterial infection, inflammation, and excessive oxidative stress. Single-atom nanozymes with multi-enzymatic activities show significant potential for promoting the healing of infected wounds by modulating their antibacterial and anti-inflammatory properties in response to the wound's physiological environment. In this study, we synthesized MN single-atom nanozymes with multi-enzymatic activities that intelligently respond to pH value changes in the wound healing process.

Background: Nitric oxide (NO) is a low-toxicity and high-efficiency anticancer treatment that can augment the cytotoxicity of doxorubicin (DOX) towards breast cancer cells, thereby exhibiting a favorable effect on chemotherapy sensitization.
Objective: The study aimed to establish a hydrogel that sensitizes chemotherapy by inducing local inflammatory stimulation to change the tumor microenvironment and promote NO production. The purpose of the study was to examine the anti-tumor effect in vivo and in vitro.
