“…34,35 To improve the antibacterial activity and cytotoxicity of Cu based materials, Yan et al 36 synthesized a hybrid material that immobilized Cu NPs on reduced GO (rGO) and montmorillonite, which showed strong antimicrobial activity against S. aureus and lower toxicity. As demonstrated by Liu et al, 37 the nanocomposites formed by GO and Cu NPs showed good antibacterial performance against Escherichia coli. Tu et al 38 found that rGO could adsorb copper ions to form a rGO-copper composite, resulting in selectively enhanced antibacterial activity of the composite without toxic effects on mammalian cells.…”

Biofilms and their associated infections have posed serious threats to the society from both an economical concern and a healthcare perspective. Graphene oxide (GO) has recently prompted the emergence of applications in the area of antibacterial materials owing to its high biocompatibility and surface functionalization. However, the weak biological interactions with microbial cells limit the antibiotic activity of GO. Herein, by combining GO with currently utilized antibacterial metal ions, copper ion‐graphene oxide composite (Cu2+@GO) with exceptional bactericidal activity is achieved in this work. Cu2+@GO composite possessed more than 95% antimicrobial efficiency of both Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) compared with the Cu2+ only group or GO only group. Additionally, the composite inhibits the formation of bacterial biofilms, making it a potential candidate for the development of alternative antimicrobials. Antibacterial mechanism study shows that Cu2+@GO has both bacteria‐binding ability and the property of producing reactive oxygen species (ROS) to cause the bacterial destruction. In vivo experiments indicate that Cu2+@GO possess an inhibition effect to P. aeruginosa‐induced keratitis. Overall, this work demonstrates that Cu2+@GO may be promising antibacterial agents for the treatment of bacterial infection, which contributes to designing more antibiotic and safe graphene‐based materials.

“…Graphene materials that have been used in resource recovery typically possess features like high specific area, oxygen functionalities, abundant active sites for molecular binding and postmodification, and thermal and chemical stability. [87] Liu et al [117] used graphene oxide nanosheets (GO NSs) as sorbents to capture copper ions in water and reduced them in situ to form copper nanoparticles (Cu NPs).…”

Population growth, urbanization, and decarbonization efforts are collectively straining the supply of limited resources that are necessary to produce batteries, electronics, chemicals, fertilizers, and other important products. Securing the supply chains of these critical resources via the development of separation technologies for their recovery represents a major global challenge to ensure stability and security. Surface water, groundwater, and wastewater are emerging as potential new sources to bolster these supply chains. Recently, a variety of material‐based technologies have been developed and employed for separations and resource recovery in water. Judicious selection and design of these materials to tune their properties for targeting specific solutes is central to realizing the potential of water as a source for critical resources. Here, the materials that are developed for membranes, sorbents, catalysts, electrodes, and interfacial solar steam generators that demonstrate promise for applications in critical resource recovery are reviewed. In addition, a critical perspective is offered on the grand challenges and key research directions that need to be addressed to improve their practical viability.

“…The metal ions or oxides of some metals possess some antibacterial properties, such as silver ions, 105 copper ions, 106 zinc oxide, 107 etc. A major mechanism of inorganic NP antibacterial activity involves the alteration of bacterial membranes and disruption of organelles, which makes them widely used as antimicrobial dressings for wounds.…”

Wound healing is a complex and dynamic process, and metabolic disturbances in the microenvironment of chronic wounds and the severe symptoms they cause remain major challenges to be addressed. The inherent properties of hydrogels make them promising wound dressings. In addition, biomembrane-based nanostructures and microstructures (such as liposomes, exosomes, membrane-coated nanostructures, bacteria and algae) have significant advantages in the promotion of wound healing, including special biological activities, flexible drug loading and targeting. Therefore, biomembrane-based nanostructure- and microstructure-loaded hydrogels can compensate for their respective disadvantages and combine the advantages of both to significantly promote chronic wound healing. In this review, we outline the loading strategies, mechanisms of action and applications of different types of biomembrane-based nanostructure- and microstructure-loaded hydrogels in chronic wound healing.
