Nanobot is an infamous term for molecules having unique properties that allow them to be programmed and carry out a particular task.

FREMONT, CA: People can build systems that can revolutionize the way they live, only if they could control atoms and molecules and gather them to do specific tasks at the molecular level. Constructing such witty and invisible nano-sized machines is one of the loftiest goals of nanotechnology.

The concept has been around for nearly four decades, but nanotechnology applications in the present time have mostly stayed passive, like car bumpers or sunscreen lotions. In the year 2020, some of the nano gear will shift from labs into the human body, home appliances, cars, food, solar panels, smart cities, and everything one can think of. A nanometre is considered as one-millionth the size of an ant or one-billionth of a meter. 

Machines that are built at such invisible measures can flow in the blood, as well as perform the tasks for which they are programmed, such as removing arterial plaque, dissolving clots, monitoring the condition of heart, liver, detecting and eradicating cancer, and redefining the saying “prevention is better than cure.”

Nanobots, in theory, can be utilized to monitor the body for maladies and other symptoms that continuously transmit information to a cloud, which can be successfully monitored by health specialists. Additionally, nanobots can be turned into biodegradable nanomaterials, which can dissolve after the task is completed. For other carbon nanotubes (a nano-sized cylinder of carbon atoms), applications, such as the ones present in cars, clothes, airplanes, or solar panels, can be deployed in making stain-resistant shirts, fuel-efficient cars, and planes with scratch-resistant paints.

Nearly 10,000 patents and more on nanotechnology have been filed with the US patent office. In the next four years, the global nanotechnology business is most likely to be seen around $125 billion, with startups to large companies, including a few leading developing products and solutions revolving around the space of nanotechnology. Several deployment and advantages can be witnessed toward the end of the 2020s, especially for the ones that are under medical use as nanoswimmers, which are to pass human trials and other regulatory obstacles. They might be considered invisible, but their influence on the world is massive and ubiquitous.
