Abstract
Drugs can be delivered using oral nanocarriers in controlled, site-specific releases. Target receptors are physically, chemically, and biologically conjugated while administering a specific medicine. Since micro carriers have a 200 nm width, nanomedicine typically refers to objects with that size. Drugs can be delivered by nanocarriers to parts of the body that are inaccessible. Nanocarriers cannot deliver large pharmaceutical dosages due to their small size. Emulsion-based nanocarriers often have poor drug loading and encapsulation, which restricts their potential for therapeutic use. Various therapeutic nanocarriers exist. Ultrabright nanocarriers, polymeric nanocarriers, smart nanocarriers, nanocomposites, protein nanocarriers, nucleic acid-based nanocarriers, carbon nanotubes, and nanobubbles are examples of novel nanocarriers. All of them have successfully treated cancer. This review looks at targeted drug delivery methods and nanocarriers.
