“… 12 , 17 These species can then cause damage to an organism’s cell membrane, DNA, and protein through Fenton type reactions, which result in cell death. 18 − 23 Some believe this oxidative stress to be the primary mode of antibacterial activity of most bactericidal metal oxides. 24 − 27 …”

Antimicrobial Properties of Copper-Doped ZnO Coatings under Darkness and White Light Illumination

We report the first antimicrobial study of transparent and robust Cu-doped ZnO coatings that displayed potent antimicrobial activity that resulted in bacterial (Escherichia coli) reduction below detection limits within 6 h of illumination via a white light source that is found in hospital environments. The same bacterial reduction rate was observed even under darkness for 4.0 atom % Cu-doped ZnO films thus providing an efficient 24 h disinfection. All films were produced via a novel, inexpensive, and easily scalable route and were also thoroughly analyzed for their material properties.

“…Recent progress in this eld was made by Baier et al 4 Delivered antibacterial agents at the wound site are, in principle, an alternative to the use of systemic antibiotics when treating wound infection. 5,6 Metal ions and metal oxides 7 have found applications in advanced antibacterial systems. 8,9 To encapsulate and release metal salts or oxides, a hydrophilic environment like a hydrogel 10,11 or a capsule with an aqueous core is more suitable than hydrophobic environments, which require the use of hydrophobic organo-metallic compounds.…”

“…Recently, spatial atomic layer deposition (SALD) has been harnessed for high throughput and large area depositions, making ALD more interesting for industrial use [6]. In addition, ALD ZnO has been studied for its reversible wettability [14,15], and it has been found to have antibacterial properties [16].…”

Hydrogen and Deuterium Incorporation in ZnO Films Grown by Atomic Layer Deposition

et al. 2021

Zinc oxide (ZnO) thin films were grown by atomic layer deposition using diethylzinc (DEZ) and water. In addition to depositions with normal water, heavy water (2H2O) was used in order to study the reaction mechanisms and the hydrogen incorporation at different deposition temperatures from 30 to 200 °C. The total hydrogen concentration in the films was found to increase as the deposition temperature decreased. When the deposition temperature decreased close to room temperature, the main source of impurity in hydrogen changed from 1H to 2H. A sufficiently long purging time changed the main hydrogen isotope incorporated in the film back to 1H. A multiple short pulse scheme was used to study the transient steric hindrance. In addition, the effect of the storage of the samples in ambient conditions was studied. During the storage, the deuterium concentration decreased while the hydrogen concentration increased an equal amount, indicating that there was an isotope exchange reaction with ambient H2 and/or H2O.
