Nanomaterials are manufactured particles with extremely small dimensions that take advantage of the nanoscale's unique physical and chemical capabilities. Nanomaterials' physical and chemical properties differ from those of larger-scale particles as a result of their smaller size, and they may behave in unpredictable and unknown ways. Chemical substances or materials that are made and used on a very small scale are known as nanomaterials. Nanomaterials are created to have unique properties compared to materials that do not have nanoscale features, such as greater strength, chemical reactivity, or conductivity.
Engineered biomaterials have been designed to resemble biological tissues and interact with biological systems. These biomaterials must have adequate physicochemical properties for a variety of medical applications, including tissue scaffolds, drug delivery systems, surgical agents (e.g., adhesive, hemostatic agents), and functional coatings of biomedical devices and bioelectronics. Biomaterials can be synthesised in laboratories utilising a variety of chemical methods. The physical, chemical, in-vitro, in-vivo, mechanical, and surface features of biomaterials are all detailed information for researchers. Bioactive glasses are surface reactive glass-ceramic biomaterials with bioglass that are primarily used as implants to repair and regenerate damaged bone.
