Recent Progress in Two‐Dimensional Antimicrobial Nanomaterials

Abstract

Nowadays, microorganisms, including bacteria and viruses, are regarded as new environmental pollutants and pose serious threats to public health. Yet, traditional disinfection approaches for bacteria and viruses are generally ineffective. Furthermore, they exhibit the disadvantages of high-energy consumption, environmental pollution, high cost, and toxic byproduct generation. In this respect, nanomaterials display promising antimicrobial capabilities due to their unique properties and provide solutions to the abovementioned issues. Herein, recent progress in the development of 2D nanomaterials displaying antimicrobial capabilities is highlighted. The structures, morphologies, and performances of essential metal, graphene, and nitride-based 2D antibacterial nanomaterials are summarized in detail. In addition, possible antimicrobial mechanisms and the relationship between structure and antimicrobial efficiency are elaborated.

Ultrathin Two‐Dimensional Semiconductors for Photocatalysis in Energy and Environment Applications

“…Profiting from the unique advantages such as stronger adsorption ability and more effective utilization of photogenerated holes and electrons, the 2D structure photocatalysts show great prospect for the photocatalytic sterilization . For example, in 2018, Wu and coworkers constructed hybrid nanosheets of g‐C 3 N 4 ‐Zn 2+ @graphene oxide via electrostatic bonding and π‐π stacking interactions.…”

Recoverable peroxidase-like Fe3O4@MoS2-Ag nanozyme with enhanced antibacterial ability

“…The increase of drug-resistant microorganism, caused by over usage of antibiotics, has become a serious public threat to human [1] , [2] . Therefore, enormous attention has been paid to urgent developing various antibacterial agents with broad-spectrum antimicrobial property and minor side effect [3] .…”

Nanomaterials for Airborne Virus Inactivation: A Short Review

“…Graphene is a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice composed of sp 2 hybrid carbon atoms. It was featured by large specific surface area, high conductivity and high charge mobility, leading to sufficient surface active sites, good adhesion to microorganisms and the efficient generation of light-induced electron/hole separation pairs (Miao et al 2019 ). In addition, as a two-dimensional material, graphene exhibits excellent surface dispersibility and can be used as a substrate for catalytic systems (Georgakilas et al 2016 ).…”
