The risk of harmful microorganisms to ecosystems and human health has stimulated exploration singlet oxygen (1O2)-based disinfection. It can be potentially generated via an electrocatalytic process, but is limited by the low production yield unclear intermediate-mediated mechanism. Herein, we designed a two-site catalyst (Fe/Mo–N/C) for selective 1O2 generation. Mo sites enhance generation precursors (H2O2), accompanied intermediate •HO2/•O2–. Fe site facilitates activation H2O2 into •OH, which accelerates •HO2/•O2– 1O2. A possible mechanism promoting through ROS-mediated chain reaction reported. as-developed electrochemical disinfection system kill 1 × 107 CFU mL–1 E. coli within 8 min, leading cell membrane damage DNA degradation. effectively applied medical wastewater. This work provides general strategy electrocatalysis efficient

Advancements in the Application of the Fenton Reaction in the Cancer Microenvironment

Pharmaceutics, Год журнала: 2023, Номер 15(9), С. 2337 - 2337

Cancer is a complex and multifaceted disease that continues to be global health challenge. It exerts tremendous burden on individuals, families, healthcare systems, society as whole. To mitigate the impact of cancer, concerted efforts collaboration scale are essential. This includes strengthening preventive measures, promoting early detection, advancing effective treatment strategies. In field cancer treatment, researchers clinicians constantly seeking new approaches technologies improve therapeutic outcomes minimize adverse effects. One promising avenue investigation utilization Fenton reaction, chemical process involves generation highly reactive hydroxyl radicals (·OH) through interaction hydrogen peroxide (H2O2) with ferrous ions (Fe2+). The generated ·OH possess strong oxidative properties, which can lead selective destruction cells. recent years, have successfully introduced reaction into microenvironment application nanotechnology, such polymer nanoparticles light-responsive nanoparticles. article reviews progress catalyzed by nanoparticles, in microenvironment, well potential applications future development directions tumor treatment.
