“…The photothermal treatment of GO for antibacterial, antifungal, and wound infection treatments using an NIR laser (Nd-YAG (λ = 1064 nm)) were reported. [ 123 ] Various pathogenic bacteria ( Pseudomonas aeruginosa, Staphylococcus aureus ) and fungi ( Saccharomyces cerevisiae, Candida utilis ) were investigated. The cytotoxicity was measured using proteomic analysis.…”

the manipulation of graphene and its derivatives occupy a relatively insignifi cant part, i.e., less than 1%. The fi rst publications on graphene modifi cation with laser irradiation appeared in 2008, however, since 2010, the number of publications has risen exponentially.Graphene oxide (GO) has emerged as a versatile material for nanocarbon research. Several types of oxygen-containing functional groups present on the basal plane, and the sheet edge allows GO to interact with a broad range of organic and inorganic materials. [ 9 ] Furthermore, GO is an abundant and low-cost material synthesized from graphite or graphite oxide; it retains a layered structure but, at the same time, it can be characterized by the loss of electronic conjugation caused by the oxy groups at the edge or plane defects. GO has a potential use in energy, [ 10 ] electronics, [ 11 ] molecular sensing areas, [ 12 ] catalysis, [ 13 ] etc. Moreover, it can be reduced chemically or thermally in order to achieve graphenelike properties. [ 14 ] The material produced during such a procedure is usually referred to as "reduced GO" (rGO). However, residual defects such as remnant oxygen atoms, [ 15 ] Stone-Wales defects (pentagon-heptagon pairs), [ 16 ] and holes [ 17 ] appearing due to the loss of carbon (in the form of CO or CO 2 ) from the basal plane [ 18 ] limit the electronic quality of rGO.A laser is a powerful tool which is used for various applications in industry, medicine, science, and material processing. [ 19 ] It is usually employed in different processes such as ablation, etching, cutting of various materials, as well as direct A dramatic rise in research interest in laser-induced graphene oxide (GO) reduction and modifi cation requires an overview of the most recent works on this subject. Typical methods for the recognition and confi rmation of modifi ed graphene and its derivatives, such as Raman, Fourier-transform infra-red (FTIR), X-ray photoelectron (XP), and ultraviolet-visible (UV-vis) spectroscopies, are introduced briefl y in this review. A major part of the survey is devoted to the main modifi cation ways and the laser parameters used in the literature. A discussion of possible reduction and modifi cation mechanisms is also presented. Recent applications, especially in the biomedical fi eld such as cell therapy treatment, as well as signifi cant results of GO modifi cation, are discussed in detail. Finally, perspectives for the application of laser-induced GO modifi cations in passive THz photonics and biomedicine are briefl y addressed.

“…For example, Khan et al demonstrated a >99% reduction in the viability of C. albicans and S. cerevisiae , utilizing graphene oxide nanoflakes under the irradiation light in the NIR region (λ = 1064 nm). [ 238 ] Furthermore, Wang and Irudayaraj demonstrated the antifungal effect of a polymer sphere when irradiated with light at wavelength 808 nm, for 5 min, observing >99% inactivation of C. albicans cells. [ 236 ] Hence, there is an obvious need for future designs of photothermal nanomaterials to be screened against relevant fungal pathogens to determine their efficacy and underlying antifungal mechanisms.…”

The development of antimicrobial drug resistance among pathogenic bacteria and fungi is one of the most significant health issues of the 21st century. Recently, advances in nanotechnology have led to the development of nanomaterials, particularly metals that exhibit antimicrobial properties. These metal nanomaterials have emerged as promising alternatives to traditional antimicrobial therapies. In this review, a broad overview of metal nanomaterials, their synthesis, properties, and interactions with pathogenic micro‐organisms is first provided. Secondly, the range of nanomaterials that demonstrate passive antimicrobial properties are outlined and in‐depth analysis and comparison of stimuli‐responsive antimicrobial nanomaterials are provided, which represent the next generation of microbiocidal nanomaterials. The stimulus applied to activate such nanomaterials includes light (including photocatalytic and photothermal) and magnetic fields, which can induce magnetic hyperthermia and kinetically driven magnetic activation. Broadly, this review aims to summarize the currently available research and provide future scope for the development of metal nanomaterial‐based antimicrobial technologies, particularly those that can be activated through externally applied stimuli.

“…80 A recent study reported the use of graphene oxide (GO) nanosheets for photothermal treatment of bacterial and fungal wound infection. 81 A synergistic effect against different pathogens was elicited by action of GO and the heat generated from the irradiation of these nanomaterials with a near-infrared Nd:YAG laser. The application of the laser and GO resulted in a faster healing of infected wounds, yielding a noninvasive alternative to antibiotic treatment.…”

The chronic nature and associated complications of nonhealing wounds have led to the emergence of nanotechnology-based therapies that aim at facilitating the healing process and ultimately repairing the injured tissue. A number of engineered nanotechnologies have been proposed demonstrating unique properties and multiple functions that address specific problems associated with wound repair mechanisms. In this outlook, we highlight the most recently developed nanotechnology-based therapeutic agents and assess the viability and efficacy of each treatment, with emphasis on chronic cutaneous wounds. Herein we explore the unmet needs and future directions of current technologies, while discussing promising strategies that can advance the wound-healing field.
