Aptamers based targeted drug delivery system: A newer trend in cancer treatment therapy

The investigation of targeted drug delivery systems as a way to improve therapeutic efficacy while minimizing adverse effects is a result of the development of novel cancer treatment strategies. This subject explores the exciting field of aptamer-based targeted drug delivery systems for the treatment of cancer. Short single-stranded DNA or RNA molecules called aptamers have a remarkable capacity to bind to particular target molecules with high specificity and affinity. Aptamers have drawn attention as excellent possibilities for creating targeted drug delivery systems by taking use of their special characteristic. The applications, choice, and modification of aptamers to precisely identify cancer-associated biomarkers, such as receptors overexpressed on cancer cells, are covered in detail in this topic. Additionally, it emphasizes various techniques for aptamer-drug conjugation optimization which ensure effective carrier delivery and regulated drug release inside the tumor microenvironment. It is investigated if aptamer-based systems have the ability to overcome problems such drug resistance, heterogeneity, and insufficient drug penetration within solid tumors.In conclusion, this article illuminates how aptamer-based targeted drug delivery systems have transformed the world of cancer treatment. It advances knowledge of these systems and their potential to transform cancer treatment by providing insights into design principles, delivery systems, and therapeutic results.
