Nanomaterials in Electrochemical Sensing Area
Recently, nanomaterials have received increasing attention due to their unique physical and chemical properties, which make them of considerable interest for applications in many fields, such as biotechnology, optics, electronics, and catalysis. The development of nanomaterials has proven fundamental for the development of smart electrochemical sensors to be used in different application fields such, as biomedical, environmental, and food analysis. In fact, they showed high performances in terms of sensitivity and selectivity.

Nanomaterials in Dentistry
       Nanomaterials are commonly considered as those materials in which the shape and molecular composition at a nanometer scale can be controlled. Subsequently, they present extraordinary properties that are being useful for the development of new and improved applications in many fields, including medicine. In dentistry, several research efforts are being conducted, especially during the last decade, for the improvement of the properties of materials used in dentistry.

Nanomaterials in Cosmetics
Compared with micro-scale cosmetics, nanomaterial-based cosmetics present unique attributes. Nanomaterials (NMs) have a larger contact surface, allowing for longer-lasting and more efficient effects. Their use is already widespread and can be commonly found in sunscreens, where they assume the function of making the product optically transparent as well as providing protection against solar radiation, or in cosmetic products, such as make-up with long-lasting color effect. Nanotechnology has a wide range of applications and has become an interesting and relevant technology in the biomedical, optical, mechanical, electronic, and cosmetic fields and in the food industry. In the cosmetic field, NMs have been extensively explored as ingredients in cosmetic products. However, the changes in the physicochemical properties of a material at nanoscale can lead to changes in their biokinetic and biological interactions and effects, compared with their macrosized equivalents. This means that some NMs could have potential intrinsic hazards that are not observed in their non-nano form.

Nanomaterials in Cosmetic
Skin aging is described as dermatologic changes either naturally occurring over the course of years or as the result of the exposure to environmental factors (e.g., chemical products, pollution, infrared and ultraviolet radiations). The production of collagen and elastin, the main structural proteins responsible for skin strength and elasticity, is reduced during aging, while their role in skin rejuvenation can trigger a wrinkle reversing effect. Elasticity loss, wrinkles, dry skin, and thinning are some of the signs that can be associated with skin aging. To overcome skin aging, many strategies using natural and synthetic ingredients are being developed aiming to reduce the signs of aging and/or to treat age-related skin problems (e.g., spots, hyper- or hypopigmentation). Among the different approaches in tissue regeneration, the use of nanomaterials loaded with cosmeceuticals (e.g., phytochemicals, vitamins, hyaluronic acid, and growth factors) has become an interesting alternative. Based on their bioactivities and using different nanoformulations as efficient delivery systems, several cosmeceutical and pharmaceutical products are now available on the market aiming to mitigate the signs of aged skin.

Nanomaterials in Cancer Therapy
This entry analyzed the different roles of nanomaterials, such as contrast agent and dose enhancer, in biomedical imaging and cancer therapy. Moreover, the review discussed the underlying mechanisms of nanomaterials including physical, chemical, and biological mechanisms. Some new applications of nanomaterials as theranostic agents are explored. Through a thorough understanding of the recent advances in nanomaterial application in biomedical imaging and cancer therapy, we identified new directions for the optimization and clinical transformation of nanomaterials.

Nanomaterials from Industrial, Biological Activities
Nanotechnology and nanoparticles are found to be very effective because of their unique chemical and physical properties and high surface area, but their high cost is one of the major hurdles to its wider application. So, the synthesis of nanomaterials, especially 2D nanomaterials from industrial, agricultural, and other biological activities, could provide a cost-effective technique. The nanomaterials synthesized from such waste not only minimize pollution, but also provide an eco-friendly approach towards the utilization of the waste.

Nanomaterials for Water Purification
While water shortage across the world is threatening the well-being of the human community, emerging advanced technologies targeted to address this challenge are promising. In this regard, nanomaterials have played a crucial role.  Nanomaterials, i.e., those materials which have at least one dimension in the 1–100 nm size range, have produced a new generation of technologies for water purification. This includes nanosized adsorbents, nanomembranes, photocatalysts, etc. Stemming from extraordinary structural characteristics and size scale of nanomaterials, the nanostructured membranes/adsorbents enable water purification with a high efficiency in terms of pollutants removal and water permeability, thereby reducing energy consumption and cost.

Nanomaterials for Viral Diseases Diagnosis, Prevention, and Treatment
Nanomaterials can be tailored for specific uses by modulating physical and chemical properties, including size, morphology, surface charge, and solubility. Due to these controllable properties, nanomaterials have been used in biosensors to potentiate target-specific reactions that respond to biochemical environments, such as temperature, pH, and the presence of enzymes.

Nanomaterials for the Treatment of Osteosarcoma
Osteosarcoma (OSA) is a type of bone cancer that begins in the cells that form bones. OSA is a rare mesenchymal bone neoplasm derived from mesenchymal stem cells. Genome disorganization, chromosomal modifications, deregulation of tumor suppressor genes, and DNA repair defects are the factors most responsible for OSA development. Advancements in nanotechnology have made it possible to deliver the drug to various diseases including OSA.
