Targeted medication delivery to the organ, tissue, or cells currently offers great opportunities in the field of drug therapy. Drug delivery systems (DDS) are essential for improving the efficacy of chemotherapy in cancer treatment. Chemotherapy is a subject of great interest since new drug delivery techniques are constantly being created. The ability of therapeutic agents to reach their intended sites and their low accumulation in non-specific sites (healthy organs and tissues) are both crucial components of anti-tumor chemotherapy success. As a result, the targeted distribution of medications to the organs, tissues, or cells is currently thought to provide wonderful prospective in the field of chemotherapy. The fundamental idea behind targeted delivery is that molecules that can be recognised by a specific receptor on cells or target sites can be used to modify delivery systems (such as the vector, containers, and others) rather than just the medication itself. These are therefore referred to as "targeted drug delivery systems." Yet, the development of multifunctional nanocarriers, such as nanoparticles, liposomes, micelles, dendrimers, and others, can greatly improve the effectiveness of numerous therapeutic and diagnostic procedures.
