“…In this section, by the term ‘nanocomposite’ and'composite’ we refer to materials consisting of at least two phases, whereby one phase, i. e. nanoparticles or particles, are included in bulk phases such as polymers, i. e. matrix [30] . However, the term ‘nanocomposite’ is also used in several publications with an emphasis on the hybrid nature of the nanoparticles, especially GO‐Ag structures, rather than on their inclusion in a bulk phase [31,32] …”

Biomedical application of graphene derivatives have been intensively studied in last decade. With the exceptional structural, thermal, electrical, and mechanical properties, these materials have attracted immense attention of biomedical scientists to utilize graphene derivatives in biomedical devices to improve their performance or to achieve desired functions. Surfaces of graphene derivatives including graphite, graphene, graphene oxide and reduce graphene oxide have been demonstrated to pave an excellent platform for antimicrobial behavior, enhanced biocompatibility, tissue engineering, biosensors and drug delivery. This review focuses on the recent advancement in the research of biomedical devices with the coatings or highly structured polymer nanocomposite surfaces of graphene derivatives for antimicrobial activity and sterile surfaces comprising an entirely new class of antibacterial materials. Overall, we aim to highlight on the potential of these materials, current understanding and knowledge gap in the antimicrobial behavior and biocompatibility to be utilized of their coatings to prevent the cross infections.

“…The synergetic effect of reduced GO and gold nanostar, known as rGO/AuNS nanocomposites under 808 nm NIR irradiation, resulted in increased photothermal and antibacterial activity through membrane disruption and hyperthermal effect, leading to complete death of methicillin-resistant S. aureus (MRSA) ( Feng et al, 2019 ). Similarly, the combination of Ag-NPs with GO the rGO/Ag nanocomposites under NIR irradiation showed enhanced photothermal activity leading to effective bactericidal potencies by disrupting the microbial membrane and generating ROS in Klebsiella pneumoniae and E. coli ( Tan et al, 2020 ). Recent reports on oxygen-deficient Ni/reduced graphene oxide (Ni/rGO) nanocomposites demonstrated enhanced photothermal and photocatalytic activity under NIR irradiation by increasing GSH loss and destroying the microbial cell membrane through the formation of O 2 •– and •OH radicals ( Zhang Z. et al, 2021 ).…”

Injudicious use of antibiotics has been the main driver of severe bacterial non-susceptibility to commonly available antibiotics (known as drug resistance or antimicrobial resistance), a global threat to human health and healthcare. There is an increase in the incidence and levels of resistance to antibacterial drugs not only in nosocomial settings but also in community ones. The drying pipeline of new and effective antibiotics has further worsened the situation and is leading to a potentially “post-antibiotic era.” This requires novel and effective therapies and therapeutic agents for combating drug-resistant pathogenic microbes. Nanomaterials are emerging as potent antimicrobial agents with both bactericidal and potentiating effects reported against drug-resistant microbes. Among them, the photothermally active nanomaterials (PANs) are gaining attention for their broad-spectrum antibacterial potencies driven mainly by the photothermal effect, which is characterized by the conversion of absorbed photon energy into heat energy by the PANs. The current review capitalizes on the importance of using PANs as an effective approach for overcoming bacterial resistance to drugs. Various PANs leveraging broad-spectrum therapeutic antibacterial (both bactericidal and synergistic) potentials against drug-resistant pathogens have been discussed. The review also provides deeper mechanistic insights into the mechanisms of the action of PANs against a variety of drug-resistant pathogens with a critical evaluation of efflux pumps, cell membrane permeability, biofilm, and quorum sensing inhibition. We also discuss the use of PANs as drug carriers. This review also discusses possible cytotoxicities related to the therapeutic use of PANs and effective strategies to overcome this. Recent developments, success stories, challenges, and prospects are also presented.

“…Magnetically reduced GO-conjugated glutaraldehyde (MRGOGA) was found to be effective in eradicating ESKAPE pathogens under NIR laser irradiation (10 min), with up to a 99% efficiency. A recent study revealed that Ag-NPs embedded in reduced GO (RGO/Ag) nanocomposites were effective and enhanced inhibition against multidrug-resistant (MDR) bacteria under NIR laser light (at an intensity of 0.30 W/cm 2 ) [ 70 , 71 , 72 , 73 ]. RGO/Ag nanocomposites were found to be effective antibacterial agents under NIR laser light against ESKAPE pathogens which exhibited antibiotic resistance.…”

An upsurge in the multidrug-resistant (MDR) bacterial pestilence is a global cause for concern in terms of human health. Lately, nanomaterials with photothermal effects have assisted in the efficient killing of MDR bacteria, attributable to their uncommon plasmonic, photocatalytic, and structural properties. Examinations of substantial amounts of photothermally enabled nanomaterials have shown bactericidal effects in an optimized time under near-infrared (NIR) light irradiation. In this review, we have compiled recent advances in photothermally enabled nanomaterials for antibacterial activities and their mechanisms. Photothermally enabled nanomaterials are classified into three groups, including metal-, carbon-, and polymer-based nanomaterials. Based on substantial accomplishments with photothermally enabled nanomaterials, we have inferred current trends and their prospective clinical applications.
