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

Antibacterial Activity of Solvothermal Obtained ZnO Nanoparticles with Different Morphology and Photocatalytic Activity against a Dye Mixture: Methylene Blue, Rhodamine B and Methyl Orange

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(6), P. 5677 - 5677

Published: March 16, 2023

In this paper, we report the synthesis of ZnO nanoparticles (NPs) by forced solvolysis Zn(CH3COO)2·2H2O in alcohols with a different number -OH groups. We study influence alcohol type (n-butanol, ethylene glycol and glycerin) on size, morphology, properties obtained NPs. The smallest polyhedral NPs (<30 nm) were n-butanol, while measured average 44 nm rounded. Polycrystalline particles 120 glycerin only after water refluxing. addition, here, photocatalytic activity, against dye mixture, three model pollutants: methyl orange (MO), methylene blue (MB), rhodamine B (RhB), closer to real situations where is polluted many chemicals. All samples exhibited good activity degradation efficiency reaching 99.99%. sample maintained high >90%, over five catalytic cycles. Antibacterial tests conducted Gram-negative strains Salmonella enterica serovar Typhimurium, Pseudomonas aeruginosa, Escherichia coli, Gram-positive Enterococcus faecalis, Bacillus subtilis, Staphylococcus aureus, cereus. presented strong inhibition planktonic growth for all tested strains, indicating that they can be used antibacterial applications, such as purification.

Vanishing Water: Rescuing the Neglected Food Resource

Food Engineering Reviews, Journal Year: 2023, Volume and Issue: 15(4), P. 609 - 624

Published: June 10, 2023

Abstract The annual global amount of water consumed to produce food ranges from 600,000 2.5 million liters per capita depending on habits and waste generation. Humans need approximately 2–3 L daily maintain health, but only 0.01% the world’s is drinkable. Food supplies cannot be generated without land, water, energy use. current use for production most concerning requires immediate increased awareness. Minimal attention has been devoted increasing scarcity loss drinking water. also contains therefore adds that affecting almost 4 billion people. We summarize human its significance life production, processing, consumption foods. This review includes an examination history water; unique properties sustaining life; including agriculture, horticulture, mariculture; exploited in processing; due demands exceeding availability or access; consequences our world. Means reduce scarcity, using treatment promoting change habits, are discussed. future recommendations action proposed decreasing reducing during preparation, consumption.

Controllable Fabrication of ZnO Nanorod Arrays on the Surface of Titanium Material and Their Antibacterial and Anti-Adhesion Properties

Materials, Journal Year: 2025, Volume and Issue: 18(7), P. 1645 - 1645

Published: April 3, 2025

The adhesion of deleterious bacteria on titanium substrates not only causes economic losses but also endangers human life and health. study is expected to address the challenging issues using ZnO as an antibacterial material, including low bactericidal efficiency without lighting, susceptibility cluster formation, easy its surface. It proposed that prepared nanorod arrays with a hexagonal wurtzite structure surface titanium-based materials can issue formation. Remarkably, mere 3.49 g cm−2 decorated Ag/AgCl achieves over 99% sterilization lighting. incorporation FAS (1H,1H,2H,2H-perfluorodecyltrimethoxysilane) molecules energy enables Ti@ZnO@Ag/AgCl@FAS attain Cassie–Baxter wetting state, thereby imparting exceptional bacterial anti-adhesion properties exceeding 99.50%. Furthermore, models have been elucidate underlying mechanisms. This innovative approach anticipated be adaptable for application across various material substrates, which opens up new avenue materials.

Published: May 18, 2023

This paper presents the preparation and characterization of a porous antimicrobial composite material consisting diatomaceous earth, an inorganic pore-forming agent, nano-zinc oxide (ZnO). A modified direct precipitation device produced high-surface area ZnO powder. The effect reaction temperature, volume flow rate, titration rate on particle size was studied. Using sodium chloride, potassium nitrate, percarbonate as porosity to create structures through dissolution also investigated. study found that adding cement sand earth improved mold strength while lowering increasing temperature increased specific surface ZnO. At 60 °C, crystalline structure changed from irregular spherical form regular nanorod structure. prepared nanorods reached over 15 m2/g, which is about five times higher. In antibacterial experiment, 5% 50 nm diameter resulted in nearly 100% against E. coli aqueous environment. results suggest earth/nano-ZnO has potential applications material, method could have broader implications materials science.
