“…Such carbon structure can exhibit fundamental properties such as large specific surface area, high mechanical strength, electron conductivity, optical and catalytic characteristics. [160][161][162][163][164][165][166][167][168][169][170][171][172][173][174] These unique properties of graphene and its derivatives have made these nanostructured materials suitable for various biological and medical applications, including antipathogenic applications. [175][176][177][178][179][180][181] In order to cope with the current COVID-19 pandemic, It should be mentioned that the antibacterial and antiviral activity of graphene or graphene-based nanomaterials can be explored based on various effects, including membrane, oxidative, and photothermal stresses as well as charge transfer, and the entrapment effect of graphene materials on various bacterial species.…”

the phylogenetic and taxonomical finding on February 11, the coronavirus (COV) study group (CGS) of the International Committee on Virus Taxonomy (ICTV) designated the virus as SARS-CoV-2. [1] The same day, the director general of the World Health Organization (WHO) designated the disease caused by SARS-CoV-2 "coronavirus disease 2019" (COVID-19). The WHO declared COVID-19 a pandemic On March 11, 2020. Globally as of June 2021, 179 686 071 confirmed cases of COVID-19, including 3 899 172 deaths, reported by WHO. [2] Reducing the burden of COVID-19 infection by developing vaccines and antiviral drugs is still a big challenge for researchers and clinicians.Nowadays, nanotechnology is a promising player in the scientific and medical fields with many applications. [3,4] A new dimension has been opened by the functionally tunable nanosized materials for industrial, biomedical, and scientific purposes, which provides a set of techniques that allow the manipulation of structural and functional properties on a microscale. [5,6] Nanotechnology is kindred with the biomedicinal involvement of nanoparticles (NPs), which are not only used as the backbone in the vaccine to formulate "nanovaccines," nanomaterial-based antiviral agents, disinfectants; which inhibit the multiplication within the host or inactivate them outside the host, but also the application of designed nanorobots to detect and repairs of tissue defects at the cellular level. [7,8] Unlike the conventional drug formulations, which typically circulate throughout the entire body parts, nanoparticles may target a desired part of the body as a targeted drug delivery vehicle. Compared to conventional vaccines, nanovaccines or surface-functionalized nanoparticles can be designed, explicitly targeting lymphatic organs and immune cells to provoke better immune responses. Moreover, the localized infections are challenging to be treated by the conventional vaccines but can be treated by the nanovaccines with specific cells or organ-targeting molecules. In some cases, the nanobased settings are applied to enhance the solubility of hydrophobic compounds. These systems are helpful to protect the antigens from degradation and stabilize a large number of therapeutic biomolecules, such as peptides, proteins, and nucleic acids on the substrate. [9] Viral infections, particularly COVID-19, have posed a severe threat to public health globally because of their wide-sphered distribution and their potent ability to change the genetic makeup. [10] Unfortunately, viruses have adopted various alternative tacticsThe COVID-19 infections have posed an unprecedented global health emergency, with nearly three million deaths to date, and have caused substantial economic loss globally. Hence, an urgent exploration of effective and safe diagnostic/therapeutic approaches for minimizing the threat of this highly pathogenic coronavirus infection is needed. As an alternative to conventional diagnosis and antiviral agents, nanomaterials have a great potential to cope with the current or even futu...

Plasmonics is a technologically advanced term in condensed matter physics that describes surface plasmon resonance where surface plasmons are collective electron oscillations confined at the dielectric-metal interface and these collective excitations exhibit profound plasmonic properties in conjunction with light interaction. Surface plasmons are based on nanomaterials and their structures; therefore, semiconductors, metals, and two-dimensional (2D) nanomaterials exhibit distinct plasmonic effects due to unique confinements. Recent technical breakthroughs in characterization and material manufacturing of two-dimensional ultra-thin materials have piqued the interest of the materials industry because of their extraordinary plasmonic enhanced characteristics. The 2D plasmonic materials have great potential for photonic and optoelectronic device applications owing to their ultra-thin and strong light-emission characteristics, such as; photovoltaics, transparent electrodes, and photodetectors. Also, the light-driven reactions of 2D plasmonic materials are environmentally benign and climate-friendly for future energy generations which makes them extremely appealing for energy applications. This chapter is aimed to cover recent advances in plasmonic 2D materials (graphene, graphene oxides, hexagonal boron nitride, pnictogens, MXenes, metal oxides, and non-metals) as well as their potential for applied applications, and is divided into several sections to elaborate recent theoretical and experimental developments along with potential in photonics and energy storage industries.

“…Depending on the composing elements, the crystal structure, and even relative angles between two layers, these materials can display a wide variety of electrical properties, including semi-metallic, metallic, semiconducting and insulating behavior. They even support exotic phenomena such as charge density waves and superconductivity [5][6][7][8][9][10]. Furthermore, magnetism at the monolayer limit has now been discovered [11,12], opening applications in nm-scale magneto-optoelectronic and spintronic devices [13,14].…”

The interest in two-dimensional and layered materials continues to expand, driven by the compelling properties of individual atomic layers that can be stacked and/or twisted into synthetic heterostructures. The plethora of electronic properties as well as the emergence of many different quasiparticles, including plasmons, polaritons, trions and excitons with large, tunable binding energies that all can be controlled and modulated through electrical means has given rise to many device applications. In addition, these materials exhibit both room-temperature spin and valley polarization, magnetism, superconductivity, piezoelectricity that are intricately dependent on the composition, crystal structure, stacking, twist angle, layer number and phases of these materials. Initial results on graphene exfoliated from single bulk crystals motivated the development of wide-area, high purity synthesis and heterojunctions with atomically clean interfaces. Now by opening this design space to new synthetic two-dimensional materials "beyond graphene", it is possible to explore uncharted opportunities in designing novel heterostructures for electrical tunable devices. To fully reveal the emerging functionalities and opportunities of these atomically thin materials in practical applications, this review highlights several representative and noteworthy research directions in the use of electrical means to tune these aforementioned physical and structural properties, with an emphasis on discussing major applications of beyond graphene 2D materials in tunable devices in the past few years and an outlook of what is to come in the next decade.
