A Review on Nanobots in Targeted Drugs Delivery System

Abstract

Nanobots in targeted drug delivery system accurately administered the drug component to a targeted area of the body (such as an organ, cellular level, or subcellular level of a specific tissue). It offers non- specific adverse effects linked to conventional drug delivery. Targeted drug delivery systems improve the efficacy and selectivity of cytotoxic medications while lowering their overall toxicity and adverse effects. The amount of medication needed to achieve therapeutic efficacy eventually decreases as a result of this method. In contrast to chemotherapy, which frequently kills all rapidly proliferating cells in order to eradicate tumor or cancerous cells, most targeted therapy approaches work to treat cancer by disrupting specific proteins that aid in the growth and metastasis of tumors in the body. This makes this approach particularly useful in the treatment of a number of diseases, including cancer.  Consequently, this enhances the efficacy of therapy and reduces unfavorable side effects. Pain, exhaustion, anemia, and issues with the skin, hair, and nails are among the side effects of cancer treatment. Nanorobotics is a new field of study that has the potential to revolutionize several fields, including biomedicine. The success of targeted drug delivery systems is aided by the use of nanorobots, particularly as carriers of therapeutic substances.  This review includes nanorobots in targeted drug delivery systems, emphasizing their design, applications, limitations and future prospects.
