Since the "birth" of graphene in 2004, two-dimensional (2D) materials have attracted unprecedented research interest from scientists and have stimulated numerous applications in various fields, such as electronic/optical devices, energy storage, catalysis, sensors, and biomedicine. In this review, we summarize recent advances in the antimicrobial applications of 2D materials, such as graphene materials (GMs), layered double hydroxides (LDHs), transition-metal dichalcogenides (TMDs), graphitic carbon nitride (g-C N ), MXenes, black phosphorus (BP), and their derivatives. This review also correlates the unique physicochemical properties of 2D materials with their antimicrobial activities. Finally, some current challenges and future perspectives in this field are also presented.

Silver‐based nanomaterials have attracted considerable attention due to their antimicrobial activities. In this work, a silver (Ag)‐based metal organic framework (Ag‐MOF) is embellished with graphene‐oxide (GO), leading to the fabrication of a novel Ag‐based nanocomposite (GO‐Ag‐MOF) whose biocidal activity is higher than those of Ag‐MOF and GO nanomaterials. The nanocomposite is characterized using X‐ray photoelectron spectroscopy, transmission electron microscopy, scanning electron microscope, Fourier transform infrared spectra, ultraviolet−visible absorption spectra, X‐ray powder diffraction, dynamic light scattering, and nitrogen gas adsorption/desorption. The characterization shows that the Ag‐MOF nanoparticles are uniformly dispersed on the GO nanosheets surfaces without any agglomeration. Toxicities of GO‐Ag‐MOF, Ag‐MOF, and GO are assessed against the Gram‐negative bacteria, Escherichia coli and the Gram‐positive bacteria, Bacillus subtilis using the growth curve, fluorescence imaging, and flow cytometry methods. GO‐Ag‐MOF shows an outstanding antibacterial activity (higher than those of the Ag‐MOF and GO alone). The interaction of GO‐Ag‐MOF and Ag‐MOF with the bacteria leads to the extirpation of 95 and 85% of live bacteria cells, respectively. This study indicates that GO‐Ag‐MOF is a promising antibacterial nanocomposite, especially for biomedical applications.

The emergence of multidrug resistant bacterial strains has hastened the exploration of advanced microbicides and antibacterial techniques. Photodynamic antibacterial therapy (PDAT), an old‐fashioned technique, has been rejuvenated to combat “superbugs” and biofilm‐associated infections owing to its excellent characteristics of noninvasiveness and broad antibacterial spectrum. More importantly, bacteria are less likely to produce drug resistance to PDAT because it does not require specific targeting interaction between photosensitizers (PSs) and bacteria. This review mainly focuses on recent developments and future prospects of PDAT. The mechanisms of PDAT against bacteria and biofilms are briefly introduced. In addition to classical macrocyclic PSs, several innovative PSs, including non‐self‐quenching PSs, conjugated polymer–based PSs, and nano‐PSs, are summarized in detail. Numerous multifunctional PDAT systems such as in situ light‐activated PDAT, stimuli‐responsive PDAT, oxygen self‐enriching enhanced PDAT, and PDAT‐based multimodal therapy are highlighted to overcome the inherent defects of PDAT in vivo (e.g., limited penetration depth of light and hypoxic environment of infectious sites).
