The rapid advancement of nanomedicine presents novel alternatives that have the
potential to transform health care. Targeted drug delivery as well as the
synthesis of nanocarriers is a growing discipline that has been intensively
researched to reduce the complexity of present medicines in a variety of
diseases and to develop new treatment and diagnostic techniques. There are
several designed nanomaterials used as a delivery system such as liposomes,
micelles, dendrimers, polymers, carbon-based materials, and many other
substances, which deliver the drug moiety directly into its targeted body area
reducing toxic effect of conventional drug delivery, thus reducing the amount of
drug required for therapeutic efficacy and offering many more advantages.
Currently, these are used in many applications, including cancer treatment,
imaging contrast agents, and biomarker detection and so on. This review provides
a comprehensive update in the field of targeted nano-based drug delivery
systems, by conducting a thorough examination of the drug synthesis, types,
targets, and application of nanomedicines in improving the therapeutic
efficiency.
