Nano-cosmetics and Nano-medicines

Abstract

In today’s fast-moving scenario, nanotechnology has already spread its wings to nanocosmetics and nanomedicines due to the wide range of physical and chemical properties associated with nanoparticles. Different types of nanoparticles, like nanoliposomes, fullerenes, solid lipid nanoparticles etc., have made their entrance into the nanocosmetic industry. However, the safety concern of nanoparticles has forced the cosmetic industry to limit their applications. The pharmaceutical industry has explored the benefits of nanotechnology; it has developed dendrimers, micelles, drug conjugates, metallic nanoparticles etc. The brief explanation of these nanoparticles provides a salient glimpse of why they are used in nano pharmaceutical and medicinal chemistry. • Metallic nanoparticles: Used for drug delivery, cancer treatment, and also in biosensors. • Nano-liposomes: Bio-compatible and possess entrapment efficiency. • Nano-emulsions: Used for controlled delivery of bioactive materials.
