“…The interaction with this material results in cell damage, loss of cell membrane integrity, and RNA leakage. 100 During copper nanomaterial production, thermal treatment, the size of films, and a number of nanomaterials are factors that may affect antibacterial levels. In regard to CuONPs -silica films, an increase in temperature from 400°C to 600°C and reduction in the thin films reduced the antibacterial activity.…”

The era of antibiotic resistance is a cause of increasing concern as bacteria continue to develop adaptive countermeasures against current antibiotics at an alarming rate. In recent years, studies have reported nanoparticles as a promising alternative to antibacterial reagents because of their exhibited antibacterial activity in several biomedical applications, including drug and gene delivery, tissue engineering, and imaging. Moreover, nanomaterial research has led to reports of a possible relationship between the morphological characteristics of a nanomaterial and the magnitude of its delivered toxicity. However, conventional synthesis of nanoparticles requires harsh chemicals and costly energy consumption. Additionally, the exact relationship between toxicity and morphology of nanomaterials has not been well established. Here, we review the recent advancements in synthesis techniques for silver, gold, copper, titanium, zinc oxide, and magnesium oxide nanomaterials and composites, with a focus on the toxicity exhibited by nanomaterials of multidimensions. This article highlights the benefits of selecting each material or metal-based composite for certain applications while also addressing possible setbacks and the toxic effects of the nanomaterials on the environment.

“…The reason was that compared with S. aureus, E. coli had an outer membrane outside the peptidoglycan layer, which could protect the bacteria cell from being attacked by extraneous compounds to a certain degree. 56,57 Conclusions Macroporous antimicrobial PAM hydrogels were one pot fabricated by in situ polymerization of AAO-in-water HIPE templates stabilized by silica N20 nanoparticles and surfactant Tween 80. It was found that on adding Tween 80 to the Pickering HIPEs, the pore structure of the polyHIPEs varied from closed-cell to open-cell.…”

Artemisia argyi oil-loaded macroporous antibacterial hydrogels were prepared by polymerization of oil-in-water Pickering high internal phase emulsions. The void interconnectivity and pore size of the hydrogels could be tailored readily by varying the concentrations of nanoparticle and small molecular surfactant.Artemisia argyi oil (AAO)-loaded macroporous antibacterial hydrogels were prepared by polymerization of oil-in-water Pickering high internal phase emulsions (HIPEs). The HIPEs were stabilized by the synergy of hydrophilic silica nanoparticles (N20) and surfactant Tween 80. The void interconnectivity and pore size of the hydrogels could be tailored readily by varying the concentrations of N20 nanoparticles and Tween 80. The mechanical properties of the porous hydrogels were related to the pore structure of the materials. There was an optimal condition for the N20 particle and Tween 80 contents where the hydrogel exhibited high compressive stress and strain. The in vitro release of the AAO-loaded hydrogels with different inner morphologies was evaluated and showed controlled release activity. The antibacterial activity of the AAO-loaded hydrogel was evaluated against Staphylococcus aureus and Escherichia coli.This kind of hydrogel exhibited excellent and long-term antibacterial activity indicating its potential use in biomedical and infection prevention applications.
