“…Therefore, numerous strategies have been employed to tailor their size, composition, morphology, and structure, which leads to a drastic change in the properties of these nanoengineered materials, making them suitable for specific applications. , Among these fluorescent materials, carbon dots (CDs), − aggregation-induced-emission luminogens (AIEgens), , metal nanoclusters (MNCs), , and some emerging two-dimensional (2D) materials such as transition-metal carbides and nitrides (MXenes) have shown immense potential . CDs are strongly fluorescent nanoparticles (NPs) with properties like nonblinking nature and facile-yet-low-cost preparation, as they do not require tedious synthetic protocols .…”

The COVID-19 outbreak has exposed the world’s preparation to fight against unknown/unexplored infectious and life-threatening pathogens. The unavailability of vaccines, slow or sometimes unreliable real-time virus/bacteria detection techniques, insufficient personal protective equipment (PPE), and a shortage of ventilators and many other transportation equipments have further raised serious concerns. Material research has been playing a pivotal role in developing antimicrobial agents for water treatment and photodynamic therapy, fast and ultrasensitive biosensors for virus/biomarkers detection, as well as for relevant biomedical and environmental applications. It has been noticed that these research efforts nowadays primarily focus on the nanomaterials-based platforms owing to their simplicity, reliability, and feasibility. In particular, nanostructured fluorescent materials have shown key potential due to their fascinating optical and unique properties at the nanoscale to combat against a COVID-19 kind of pandemic. Keeping these points in mind, this review attempts to give a perspective on the four key fluorescent materials of different families, including carbon dots, metal nanoclusters, aggregation-induced-emission luminogens, and MXenes, which possess great potential for the development of ultrasensitive biosensors and infective antimicrobial agents to fight against various infections/diseases. Particular emphasis has been given to the biomedical and environmental applications that are linked directly or indirectly to the efforts in combating COVID-19 pandemics. This review also aims to raise the awareness of researchers and scientists across the world to utilize such powerful materials in tackling similar pandemics in future.

“…Nanoparticle hyperthermia, a method for using nanoparticles in cancer heat therapy, involves heating tumors to kill cancer cells. Cancerous tumors can be removed using this form of treatment with little harm to the body [1,38,61]. It has been demonstrated that heating cancer tumors with metal-oxide nanoparticles and a magnetic field activates the immune system to fight cancer cells in other places of the body.…”

“…In last few years, lots of development has been observed in the field of biomaterials. A recent report states that between 2019 and 2024, the biomedical market will expand from USD 105 billion to USD 207 billion resenting a 14.5 % compound yearly growth rate [1]. According to the American National Institute of Health, biomaterials are the substances that could be used in the short term for analysing, healing, or enhancing the function of the body [2].…”

Biomaterials technology has advanced significantly in recent years and 2D nanostructures have played a key role in this advancement. A new ceramic 2D nanomaterial, MXene, made up of transition metal carbides, carbonitrides and nitrides with a planar layout that was produced by etching away “A” from a ceramic phase called “MAX”, has emerged to overcome the shortcomings of traditional biomaterials. MXene is used inadequately in biomedical applications due to its weak stability in physiological conditions, lack of prolonged and low biodegradability, and self‐controlled drug release. These drawbacks have given rise to the idea of using MXene/Polymer nano composites, due to their major properties like large surface area, metallic conductivity, biocompatibility, hydrophilicity, and size tunability. Polymer functionalization is possible by the surface‐available functional groups. This review has been done to focus on cutting‐edge examples such as polymer functionalized composites MXene for the developing field of biomedical applications. These applications consist of precise and prolonged antimicrobial activity, bio sensing, therapeutics, drug delivery, contrast‐enhanced diagnostic imaging, tissue engineering, flexible electronics, and bone regeneration.

Bacterial resistance to antibiotics is an important issue in contemporary society. To date, infection‐related problems persist despite intensive research efforts by chemists and biologists. Much effort has been devoted over the last decade to the development of organic/nonmetallic inorganic nanocompounds with antimicrobial activities for overcoming human infections and illnesses produced by antibiotic‐resistant pathogens. Both organic nanomaterials such as chitosan nanoparticles and conductive‐based polymer nanocompounds, as well as nonmetallic inorganic nanomaterials such as carbon‐based nanocompounds and modified nanoceramics, have been manufactured and employed in medicine for treating multidrug‐resistant infections. This review describes the most recent advances in the biomedical applications of antibacterial organic/nonmetallic inorganic nanocompounds.
