Recent Advancements In Nanobotics

What is nanorobotics?

‘Nano’ is derived from the Greek word 'Nanos' which means 'dwarf’. Nano robots are not bigger than a thousandth of a millimeter and can be even smaller.

Nanorobotic refers to the nanotechnology engineering domain of modelling.

To build nanorobots along with the device volume ranges from 0.1 to 10 micrometers. There are various kinds of terms to describe such nanorobots that have been used in research presently it includes nanotool, nanotoid, nanite, nanomachine, or nanomite. 

The first Nano-sized robots were reported in 2005, Nano-car also introduced made by fullerene molecules. At 2010 three leading designs of nanorobots are ensued- helices (also called Nano swimmers), nanorods (also called Nano swimmers, Nano motors.)

In research development phase nanomachines are widely used. There are many machines as such being tested currently in order to find it’s application of nanomedicine.


Nanorobots are majorly used in Nano medicine eg, computational genes when inducted into the body in order to restore or perceive damages and infections. In an outlook that are entirely programmed to remain the cells that are damaged or diseased. Their way of method is identical to antibodies in a more natural way of healing system.

Nanorobots are robots that reach out to certain processes that can be effectively used for drug delivery and are approx.(5-100nm) wide. Using nanotechnology the drug can be navigated to a precise location where it pulls out great efficacy of the drug and it reduces the probability of contracting the side effects. 

Generally, the drug work through the whole body before reaches the disease affected area. A device is effective to view the sugar level in the blood. 

There is a unique sensor that is available where it can be put in the human blood under the skin, where microchips are coated with human molecules, they are formulated in the way it emits an electrical impulse signal so that it monitors sugar level in the blood.

Robotics is widely contemplated in medicine and biosciences. They are programmed in such a way that it is programmed to execute surgery on regular basis. Nanobiotechnology shows another branch in robotics resulting in the growth of nanorobots which is referred to as nanobots.

Nanobots are miniaturized so that they are introduced in the human body, through vascular system travels to various vessels of the body as well as other cavities in the body. This surgical nanobot can be manipulated by the surgeon more autonomously as the surgeon inside the body. 

Many other functions can be performed by nanomanipulation such as searching for pathology, diagnosing, removal or correction of the lesion can be executed.

Nanobots can execute detailed surgery or refined intracellular surgery far beyond the ability to manipulate through a human hand.
