Photocatalytic Antimicrobials: Principles, Design Strategies, and Applications

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(22), P. 12371 - 12430

Published: Aug. 24, 2023

Nowadays, the increasing emergence of antibiotic-resistant pathogenic microorganisms requires search for alternative methods that do not cause drug resistance. Phototherapy strategies (PTs) based on photoresponsive materials have become a new trend in inactivation due to their spatiotemporal controllability and negligible side effects. Among those phototherapy strategies, photocatalytic antimicrobial therapy (PCAT) has emerged as an effective promising strategy recent years. In process treatment, are excited by different wavelengths lights produce reactive oxygen species (ROS) or other toxic killing various microbes, such bacteria, viruses, fungi, parasites, algae. Therefore, this review timely summarizes latest progress PCAT field, with emphasis development antimicrobials (PCAMs), underlying mechanisms, design multiple practical applications local infections therapy, personal protective equipment, water purification, coatings, wound dressings, food safety, antibacterial textiles, air purification. Meanwhile, we also present challenges perspectives widespread implementation therapeutics. We hope result review, will flourish weapon against antibiotic

Sonocatalytic hydrogen/hole-combined therapy for anti-biofilm and infected diabetic wound healing

National Science Review, Journal Year: 2023, Volume and Issue: 10(5)

Published: March 6, 2023

It is a great challenge to effectively eradicate biofilm and cure biofilm-infected diseases because dense extracellular polymeric substance matrix prevents routine antibacterial agents from penetrating into biofilm. H2 an emerging energy-regulating molecule possessing both high biosafety tissue permeability. In this work, we propose concept of sonocatalytic hydrogen/hole-combined 'inside/outside-cooperation' anti-biofilm for promoting bacteria-infected diabetic wound healing based on two-dimensional piezoelectric nanomaterials. Proof-of-concept experiments using C3N4 nanosheets as representative catalyst with wide band gap have verified that sonocatalytically generated holes rapidly penetrate inhibit bacterial energy metabolism oxidatively deprive polysaccharides/NADH in destroy the membrane/electron transport chain, respectively, inside/outside-cooperatively eradicating A model used confirm excellent vivo performance therapy, remarkably improving healing. The proposed strategy hole/hydrogen-combined will make highway treatment deep-seated infection.
