Summary: Electrocatalytic nitric oxide generation from nitrite within a dual-lumen catheter was successfully demonstrated, showing potent antimicrobial and antithrombotic properties. However, the sensitivity of the catalysts to oxygen and the reaction between oxygen and diffused nitric oxide limited the effectiveness of this approach under aerobic conditions. A new oxygen-tolerant catalyst and an immobilized glucose oxidase enzyme-coating approach were developed to overcome this limitation, achieving effective nitric oxide fluxes even in the presence of oxygen.

Summary: This research introduces a type of nanogels capable of controlled and sustained release of nitric oxide (NO) and hydrogen sulfide (H2S). The nanogels exhibited excellent dispersion and cytocompatibility, making them suitable for biomedical applications. The release profiles of NO and H2S were consistent and regulated, with a cumulative release of approximately 94-96% within 96 hours. Additionally, these nanogels showed antibacterial properties against Escherichia coli and Staphylococcus aureus strains.

Summary: The release of NO upon photodissociation of nitroaromatic compounds is influenced by the interaction between the NO2 group and substituent in the ortho position. Two distinct NO elimination channels are observed with a bimodal translational energy distribution of the NO photofragment. The hydrogen bonding ability of the ortho substituent regulates the ratio of slow-to-fast branching for NO release, with OH and NH2 favoring the roaming mechanism.

Summary: Nitrite and nitric oxide are critical nitrogen oxides in the nitrogen biogeochemical cycle, capable of interacting with heme-copper oxidases for enzymatic interconversion and inhibition. While they show similar biochemical properties, they are treated as distinct molecules by bacterial cells and have different effects on enzymes and sensing systems.

Summary: In this study, the controlled release of nitric oxide (NO) from alginate microspheres was achieved through the direct impregnation of S-nitroso-N-acetyl-penicillamine (SNAP) in the gelation of sodium alginate with calcium ions. The loading rate of SNAP in alginate microspheres ranged from 0.69% to 27.5%, and the longest NO release time reached up to 93 hours. The NO-releasing spheres demonstrated excellent antibacterial properties against Escherichia coli and Staphylococcus aureus, and showed great potential for biomedical applications.

Summary: Nitrogen oxides play a significant role in environmental pollution, highlighting the importance of developing techniques to treat these gas emissions. The selective catalytic reduction of NOx with carbon, instead of NH3, is a promising alternative technology. This study focuses on synthesizing carbon catalysts that are effective in reducing NO emissions. Surface modifications, including introducing nitrogen and oxygen functionalities and copper as a metallic phase, significantly enhance the catalytic activity. The optimal copper-to-carbon mass ratio of 10% leads to 100% NO conversion at 440 degrees C, indicating the high performance of the AC_M_BM@10Cu catalyst. The presence of N2 and CO2 was confirmed, while N2O and CO were not detected. Some catalyst deactivation was observed after 38 hours of reaction.

Summary: This study reported the preparation of NO-releasing poly(n-butyl methacrylate) films by incorporating S-nitroso-N-acetylpenicillamine, and investigated the NO-releasing profiles of such films under physiological conditions. The results showed that the PBMA films doped with SNAP exhibited good NO-releasing performance with antimicrobial and anti-biofilm properties against bacteria. This controllable NO release using PBMA films could be beneficial for therapeutic or biomedical device applications.

Summary: This article introduces a urinary catheter-based sensor for detecting the most common E. coli bacteria in urinary tract infections associated with the use of urinary catheters. By incorporating a nitrosating agent and indole into a silicone catheter, a red dimeric product called indoxyl red is generated, allowing for highly sensitive and specific color-based indole sensing. The method can be applied in real catheters to detect indole and E. coli in urine.

Summary: Patients with chronic rhinosinusitis often have biofilms that are resistant to antibiotics. This study found that S-nitrosoglutathione (GSNO) combined with gentamicin can effectively disperse and reduce the density of biofilms in patients. GSNO treatment also improved the mucociliary clearance by increasing the ciliary beat frequency (CBF).
