Nanotechnology is the study of smaller structures ranging in size from 0.1 to 100 nanometers. Pharmaceutical nanotechnology is concerned with the construction and development of small structures such as atoms, molecules, or compounds with sizes ranging from 0.1 to 100 nm into structures that can be further developed into unique devices with desired features and characteristics. Nanotechnology in pharmaceutics aids in the development of more advanced drug delivery systems, making it a valuable and potent tool as an alternative to conventional dosage forms. Pharmaceutical nanotechnology aids in the fight against a variety of diseases by recognizing antigens linked to diseases as well as the pathogens and viruses that cause them. It has been effective in overcoming various drawbacks of traditional dose forms such as pills and capsules.
