Nanorobots Introduction and its Medical Applications

A nanorobot is an extremely small robot that is designed to perform specific tasks at the nanoscale dimension of few nanometers i.e. 1 nm = 10-9 meter. In healthcare IT industry, this technology brings a great boom  & helps in protecting & maintaining the human body against viruses or bacteria. Researchers in robotics industry will use the pollution-free process to build cheapest & inexpensive nanorobots.

To replace worn out units, nanorobots might also produce a replica of themselves known as self-replication.  Other common names of Nanorobots are Nanomites, Nanobots, Nanites etc ranging from 0.01 to 0.1 micrometres. In our previous article, we explain Medical Robots, Artificial Intelligence, Digital Imaging, Virtual Reality, Cloud computing in healthcare, Hospital information system, Augmented reality, Medical technologies, laboratory information system etc in detail. In this article, we are going to describe Nanorobots & its Applications in Medicine field.

Introduction to Nanorobots in Medicine:

Advancement in technology has really manipulated the world around us on an ever decreasing scale. These robots play a key role in the field of biomedicine particularly used for the removal of kidney stone, treatment of cancer & elimination of defected part in the DNA structure etc. Here we are going to explain how these robots work, its application in detail. Have a look.

How Nanorobots Work?

Suppose you visit a doctor for a common disease treatment, instead of giving treatment he/she sends you to a special team who implants small robots in your bloodstream. These robots will recognise the cause of your illness and provide a dose of medication directly to an infected area. It feels awesome when you got to know quickly about the cause of your problem. These robots are known as Nanorobots which greatly transforms the future of healthcare & eventually cure everything from cancer to haemophilia.

As per research theories, nanorobots will possess at least two-way communication. Through sound waves, these robots will receive power or even reprogramming instructions from an external source and will respond to acoustic signals. A special network of stationery nanorobots will be positioned throughout the body which will keep the track of each active nanorobot passes & then report the results. Physicians or doctors could not only monitor a patient progress but can also change the instructions of the nanorobots in vivo to progress to another stage of healing. After treating, these nanorobots would be flush out of the body immediately.

Nanorobots in cancer treatment

Cancer is a big disease which would be untreatable if not diagnose early. At the time of cancer treatment, the patient had to undergo long chemotherapies which will adversely affect other human cells. This traditional radiation treatment of chemotherapy kills not only the cancer cells but also the healthy human cells which lead to hair loss, depression, nausea & fatigue. The other alternative of this painful chemotherapies is nanorobots. Doctors would offer the patient an injection of a special type of nanorobot that would check & destroy the cancer cells without touching the healthy ones. This great enhancement would raise the standard of healthcare at great extent.

Applications of Nanorobots in Medical Field

Nanorobots in the medical field can perform a wide range of tasks in monitoring, diagnosis & treating diseases. Inside the human body, these robots deliver specific drugs or medicine into the specific targets & sites. Let’s have a look at nanorobots applications in the medical field.

  • Treatment & Diagnosis of Diabetes: To maintain the human metabolism, glucose molecules are carried through the bloodstream. To determine the need for injecting insulin inside the body, glucose monitoring nanorobots uses the chemosensor.
  • Dentistry: For dental treatment, the nanorobots used are dentifrobots which induce desensitise tooth, oral analgesia, straighten irregular set of teeth.
  • Deliver the drug: Nanorobots used for drug delivery is Pharmacytes which will transport the drug to the targeted point. The dosage of the drug will be loaded into the payload of the pharmacyte.
  • Surgery: Surgical nanorobots can act as a semi-autonomous onsite surgeon will perform various functions such as diagnosing, detection of pathology, correcting lesions by nanomanipulation etc.
  • Cancer Detection & treatment: Nanorobots are made up of a mixture of protein & a polymer known as transferrin which is capable of detecting tumour cells. These robots kill the cancer cells without damaging the healthy cells which will lead to hair loss, nausea etc.
  • Gene Therapy: Genetic disease can be treated by nanorobots by comparing the molecular structure of both proteins & DNA found in the cell.
