Nanorobotics in Targeted Drug Delivery Systems

Abstract

Nanorobotics is an innovative development to the current pharmacology and drug delivery scientific scenario of this century; because the nanobot can target diseased tissues more accurately. These nanoscale machines, which have been designed with concepts of nanotechnology, molecular biology, and biomedical engineering can navigate complex biological systems, detect pathological locations, and deliver therapeutic agents in a targeted and localized fashion. This review provides an extensive discussion of the design, classification, mechanisms, fabrication methods, and biomedical uses of nanorobots in targeted drug delivery. Special focus given to cancer treatment, cardiovascular, neurological and infectious diseases. Discussion on pharmacokinetics, biocompatibility, ethical issues and compliance with specificities of nanorobotics. Although major progress has been achieved, issues like high costs of production, toxicity, and limited clinical translation are still hurdles to wide usage. The presence of AI alongside smart biosensors and customized medicine strategies is noted in future forecasts to boost the efficacy of nanorobotics.
