“…Silver nanoparticles have also been employed to coat stainless steel surfaces, as most medical devices are made of stainless steel. The synthesis of lysozyme–silver nanoparticles and electrophoretically depositing them on the surface of instruments such as scalpel blades has recently been reported [ 41 ]. Erkoc and Uluchan-Karnak [ 42 ] demonstrated the use of silver, gold, magnesium oxide, copper oxide, titanium oxide, and zinc oxide nanoparticles to produce coatings with antimicrobial properties.…”

The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global health problem that the WHO declared a pandemic. COVID-19 has resulted in a worldwide lockdown and threatened to topple the global economy. The mortality of COVID-19 is comparatively low compared with previous SARS outbreaks, but the rate of spread of the disease and its morbidity is alarming. This virus can be transmitted human-to-human through droplets and close contact, and people of all ages are susceptible to this virus. With the advancements in nanotechnology, their remarkable properties, including their ability to amplify signal, can be used for the development of nanobiosensors and nanoimaging techniques that can be used for early-stage detection along with other diagnostic tools. Nano-based protection equipment and disinfecting agents can provide much-needed protection against SARS-CoV-2. Moreover, nanoparticles can serve as a carrier for antigens or as an adjuvant, thereby making way for the development of a new generation of vaccines. The present review elaborates the role of nanotechnology-based tactics used for the detection, diagnosis, protection, and treatment of COVID-19 caused by the SARS-CoV-2 virus.

“…In this scenario, metals, semiconductors, and inorganic materials are gaining increased attention as broad-spectrum antiviral agents to protect surfaces and packaging, thus preventing new infections in humans [ 19 ]. Very recently, Ghaffari et al [ 20 ] discussed efforts to deploy nanotechnology, biomaterials, and stem cells in each step of the fight against SARS-CoV-2, while Basak and Packirisamy [ 21 ] have discussed several nanotechnological strategies that can be used as antiviral coatings to inhibit viral transmission by preventing viral entry into host cells. In this context, metal oxide nanoparticles and their composites were established as potent antibacterial agents due to the induced generation of reactive oxygen species (ROS) and the subsequent oxidative stress [ 22 , 23 ].…”

COVID-19, as the cause of a global pandemic, has resulted in lockdowns all over the world since early 2020. Both theoretical and experimental efforts are being made to find an effective treatment to suppress the virus, constituting the forefront of current global safety concerns and a significant burden on global economies. The development of innovative materials able to prevent the transmission, spread, and entry of COVID-19 pathogens into the human body is currently in the spotlight. The synthesis of these materials is, therefore, gaining momentum, as methods providing nontoxic and environmentally friendly procedures are in high demand. Here, a highly virucidal material constructed from SiO2-Ag composite immobilized in a polymeric matrix (ethyl vinyl acetate) is presented. The experimental results indicated that the as-fabricated samples exhibited high antibacterial activity towards Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) as well as towards SARS-CoV-2. Based on the present results and radical scavenger experiments, we propose a possible mechanism to explain the enhancement of the biocidal activity. In the presence of O2 and H2O, the plasmon-assisted surface mechanism is the major reaction channel generating reactive oxygen species (ROS). We believe that the present strategy based on the plasmonic effect would be a significant contribution to the design and preparation of efficient biocidal materials. This fundamental research is a precedent for the design and application of adequate technology to the next-generation of antiviral surfaces to combat SARS-CoV-2.

“…Furthermore, different mechanisms are reported on the Antimicrobial activity of graphene, including size-dependent microbial cell entrapment and cutting mechanism or oxidative stress generated upon graphene interactions. [12,42] Yu et al reported that the size of the graphene oxide sheet plays a vital role in the antibacterial mechanism. Smaller GO sheets showed reduced cell entrapment but more cell cutting activity, while the larger GO sheet size was related to more cell entrapment.…”

“…On the other hand, reducing the oxygen-rich functional group on GO either by chemical treatment or thermal annealing leads to reduced graphene oxide(rGO). [11,12] These hydroxides and epoxide functional groups and the associated defects on the honeycomb structure due to either substitution by heteroatoms or the conversion of sp 2 to sp 3 arrangement of some carbon atoms on the GO/rGO basal plane provide additional sites of interactions that can be used for catalytic and biomolecule or drug interactions. Different types of defects can be observed on the graphene structure, disrupting the uniform distribution of delocalized electrons.…”

Nanotechnology has provided us with unimaginable possibilities in addressing worldly challenges. Since its discovery in 2004, Graphene has been considered a "Holy Grail" of nanomaterials for its unprecedented applicability in different fields, including biomedical, energy harvest and storage, sensing applications. Throughout the world, tremendous waves of research have been going on to exploit graphene's unique thermal, mechanical, electrical, catalytic, and biological properties. Besides, efficient and tunable techniques of graphene's bulk manufacturing have been under thorough investigation. This article reviews various recent studies on large-scale graphene synthesis with tunable properties. Several different ways of graphene's use in various catalytic platforms are also reviewed. Furthermore, recent biomedical and energy (storage and harvest) applications of graphene, especially in microbial fuel cell technology, bio-sensing, antimicrobial applications, have been discussed in this article.
