“…Nanotechnology has evolved as cutting-edge technology in variety of sectors due to the unique, interesting, and improved properties of nanomaterials. Nanomaterials have at least one particle dimension in nanometer range (1–100 nm), and their properties are significantly different owing to higher surface area compared to bulk phase of the material. − The properties of nanoparticles (NPs) vary with morphology, composition, and purity which allows tunability of the properties according to application requirements. − Nanotechnology has made significant advancements in different sectors such as medical, , agricultural, electronic, − engineering, , computational, and materials science. ,− In the last few decades, biomedical applications such as drug delivery, anticancer activity, antimicrobial activity, topical gel activity, dental tissue engineering, bone repair, topical imaging, and SERS of NPs have gained significant attention employing their superior properties. − …”
