Nanobots have the potential to enhance the processes in medicine and healthcare. See how!   

FERMONT, CA: Nanomedicine provides the prospect of new robust tools to treat human illnesses and improve the health conditions with the help of nanobots. Super-smooth surfaces of these bots will increase the probability of boosting the immune system of the body, offering legitimate care delivery. In drug delivery, nanobots can give a number of benefits over current techniques, which include increased bioavailability, targeted therapy, and minimized surgical and human errors. Here are a few applications on how nanobots pave the way for efficient patient care via innovative methods.

 Cancer Detection 

 The nanobots are produced from a polymer-blend, and a protein called transferrin that can detect tumor cells. The nanorobots would act as an embedded chemical biosensor, that can be used for tumor detection. Medical nanorobots with chemical biosensors can be programmed to identify various concentrations of E-cadherin and beta-catenin, helping to identify targets and deliver drugs. The nanobot can also carry the chemicals used to treat cancer at the site in chemotherapy. The robots could either directly attack tumors with lasers, microwaves or ultrasonic signals, or as part of a treatment for chemotherapy, delivering medication to the cancer site.

Surgeries

The programmed surgical nanobot can function within the body as a semi-autonomous on-site surgeon. It would conduct multiple tasks such as on-board computer-coordinated pathology detection, diagnosis, correction of lesions through nano-manipulation. Surgical nanobots could be inserted into the body through the vascular system or into different vessels and other cavities in the human body at the ends of catheters. A surgical nanobot, guided by a human surgeon, may act within the human body as a semi-autonomous on-site surgeon.

In the near future, nanobots could be used for micro-eye surgery as well as retina and surrounding membranes surgery. Furthermore, nanorobots could be injected elsewhere in the body instead of injecting directly into the eye, and the drug's delivery can be guided to the eye.  Nanobots can provide better access to the regions which need surgery and induce minimal trauma. Similarly, developments in nanorobotics could also benefit other challenging surgeries

Diagnostics

Medical nanobots perform a wide range of diagnostic tasks, screening, and tracking, both in tissues and in the bloodstream. These instruments could record and report all vital signs from all distinct areas of the body continually, including temperature, pressure, chemical composition, and immune system activity. Diagnostic nanobots play a major role in detecting infections.  

Body Surveillance

The wireless transmission and operation of nanobots enable continuous monitoring of vitals parameters such as body temperature and more, that leads to a quantum leap in diagnostics. This would also assist in responding quickly to the sudden change in the vital parameters, and also warn against the possible danger, such as high blood glucose levels in the case of diabetics.

Gene Therapy

The medical nanobot is used in treating genetic diseases by comparing the molecular structure of both DNA and proteins found in the cell. Nanotechnology advancements offer safer approaches to delivering DNA into the body's cells than using viral vectors.   

It is anticipated that the nanorobots used in medicine provide a wealth of promise. The nanorobots are discovered to be more innovative, supporting precision therapy and diagnosis.

The objective of nanorobotics is not only to evaluate the therapeutic efficiency but to identify the clinical risk as and cater to it in terms of efficiency. To facilitate the same, the manufacturing of nanobots must be optimized with special regard for material biocompatibility and degradation. In addition, appropriate requirements should be implemented to innovate the benefits of nanobot therapy over traditional ones, along with complying with FDA norms. All in all, nanobots could possibly enhance therapy and medical diagnosis undoubtedly.
