This paper reviews the potential applications of nanorobots in oncology, cardiology, neurology, respiratory medicine, and nephrology, emphasizing their role in precision drug delivery, cancer therapy, diagnostic procedures, surgical interventions, and disease management. Nanorobots perform particular tasks with great accuracy and precision. They are capable of sensing the environment, transmitting signals to technicians, processing information, and exhibiting intelligence at the nanoscale. They are utilized for treating various illnesses in medical specialties such as cardiology, respiratory, neurology, nephrology, and ophthalmology. Nanorobots can be primarily used in surgery. The material characteristics, such as non-toxicity and biocompatibility, are critical for their safe interaction within the human body. Furthermore, various insertion methods, including intravenous and intra-tumoral injections, are explored. Future advancements are anticipated to enhance multifunctionality, targeting specificity, and integration with artificial intelligence, leading to more autonomous and efficient nanorobots. The integration of nanorobots in medical practice could revolutionize healthcare by offering minimally invasive, highly precise, and personalized treatment options, significantly improving patient outcomes and quality of life.
