“…The antibacterial effect of the cotton fabrics functionalized with the zein particles, with and without ellagic acid, observed for E. coli was similar to the effect described for other antimicrobial textiles developed [55][56][57][58][59][60][61]. However, for S. aureus the antibacterial effect presented by the textiles was lower when compared to the values reported in other works [62].…”

In this work, zein, a by-product of the agricultural industry of corn, was used to impart hydrophobicity and antimicrobial activity to textiles. The cotton textiles were functionalized with zein in two different forms, free or as particles. The optimized coating conditions which rendered the highest hydrophobic character to the textiles were found to be 50 g/L zein in the free form prepared with 70% ethanol. To enhance the antimicrobial activity of the coated textiles, ellagic acid was encapsulated into the zein particles. These presented stable diameters, between 300 and 450 nm, and positive surface charge revealing high encapsulation efficiency. After textiles coating, the controlled release of ellagic acid was tested against different mimetic biologic solutions. The release profile was dependent on the ethanol concentration, on the sweat solution pH and on the external media used during dialysis. The functionalized textiles revealed differentiated antimicrobial activity against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). For E. coli the activity was mainly related with the action of zein while for S. aureus a combined effect between the protein and the ellagic acid was observed. The results herein presented pave the way for the development of new zein-based products for a wide range of applications.

“…Broadly, contact-killing surfaces refer to these surfaces that can kill microbes upon contact due to the physicochemical interactions between the surfaces and microorganisms. In the past, several well-known antimicrobial compounds like quaternary ammonium compounds and chitosan have been widely used for contact-killing and have been applied in plasma-based strategies for the fabrication of contact-killing surfaces [32,33]. In the study of Song et al [33], an atmospheric pressure dielectric barrier discharge plasma was employed to activate three commercial wiping materials (i.e.…”

Modern society is suffering from many infectious microbes. Developing antimicrobial surfaces for biomedical decontamination and sterilization is one of the strategic solutions to mitigate the spread of infectious pathogens. Here, we outline the paradigm of plasmas for biomedical decontamination by presenting approaches of plasmaengineered antimicrobial surfaces and novel plasma-active antimicrobial surfaces. Low-temperature plasma can not only be used as a material fabrication tool for antimicrobial surface engineering but also be used directly for microbial inactivation by specially designed plasma-active surfaces that can effectively destroy microorganisms through exposure to plasma. The role of plasmas in the two different kinds of antimicrobial surfaces is discussed along with their associated advantages and disadvantages. Future research directions, challenges, and opportunities in both plasma-based antimicrobial surfaces are also critically evaluated. This analysis contributes to the development of next-generation antimicrobial surfaces for future bio-safety.

“…Therefore, the potential risk goes beyond the intended boundary to human health and to the environment [310]. There are also increasing concerns regarding the development of antibiotic-resistant bacteria from the environmental release of BACs [288,[312][313][314][315][316][317][318]. BACs are in the class of halogenated organic compounds that can be persistent in the environment [298].…”

A Review on the Fate of Legacy and Alternative Antimicrobials and Their Metabolites during Wastewater and Sludge Treatment

Antimicrobial compounds are used in a broad range of personal care, consumer and healthcare products and are frequently encountered in modern life. The use of these compounds is being reexamined as their safety, effectiveness and necessity are increasingly being questioned by regulators and consumers alike. Wastewater often contains significant amounts of these chemicals, much of which ends up being released into the environment as existing wastewater and sludge treatment processes are simply not designed to treat many of these contaminants. Furthermore, many biotic and abiotic processes during wastewater treatment can generate significant quantities of potentially toxic and persistent antimicrobial metabolites and byproducts, many of which may be even more concerning than their parent antimicrobials. This review article explores the occurrence and fate of two of the most common legacy antimicrobials, triclosan and triclocarban, their metabolites/byproducts during wastewater and sludge treatment and their potential impacts on the environment. This article also explores the fate and transformation of emerging alternative antimicrobials and addresses some of the growing concerns regarding these compounds. This is becoming increasingly important as consumers and regulators alike shift away from legacy antimicrobials to alternative chemicals which may have similar environmental and human health concerns.
