The future nanobots will be made with DNA
DNA
When you hear about a robot, you might think that it is a device made of iron in the shape of a human, which is trying to talk, walk, or act like a human. But not human size, scientists are trying to make many tiny robots. All of these microbots are expected to play a significant role in the medical field. Suppose your foot hurts somewhere. The doctor then gave you some food medicine. After taking the medicine, the medicine reached the sore spot of your foot through the blood from your stomach and the medicine started working. But the problem is that the medicine will spread to other parts of the body as well as to the feet. Many times after the medicine reaches these unnecessary places, it causes adverse reactions, which we call side-effects. All medicines have some side effects and scientists are trying to reduce them.
In addition to reducing the side-effects of the drug, a new strategy is being considered - the drug will only reach where it is needed. This method is called drug delivery. It is being considered to deliver medicine to a specific place in different ways. There is a lot of research going on about how to reach with a nano-sized robot or nanorobot. Nano or nanometer is a unit of length measurement. One nanometer is a fraction of 100,000,000,000ths of a meter or a meter. This nanometer is so small that it cannot be seen with the naked eye.

Medication will be given with the nanorobot and it will be injected into your bloodstream. The nanorobot will swim through the bloodstream to reach the problem site and deliver the medicine. We have heard many such myths in stories and movies. But scientists are now trying to turn it into reality, not imagination.
Over the past decade, scientists have been trying to build nanorobots in a variety of ways. What can be used to make these nanorobots? Scientists have been working for a long time to find such good materials. They are trying different types of nano-sized materials such as nanofibers, carbon nanotubes, nanocrystals, etc. These materials are excellent but the process of making something nano-sized with them is very difficult. Not that it is not possible to make nano-sized objects with these materials. It is also possible to create something with our semiconductor technology, through which computer processors and small circuits are made. These technologies are called fabrication technologies. The problem is that making with nano-sized fabrication technology is time-consuming and costly.
Scientists were looking for a material that could be easily programmed, we would design and create it yourself. This process of self-assembling is called self-assembled. At that time Paul Rothemund of Caltech University came with a message of hope. In early 2006, Paul stunned the world by creating a map of the world in nanosize with our familiar DNA.
DNA is the huge information center in the cells of our body that is passed on from one generation to the next. This DNA is basically made up of four components which are A, T, C and G. The funny thing is that A is only connected to T and G is only connected to C. Paul showed that if a beautiful template like this could be created using this feature, it would be possible to create anything like a nano-sized mind. The funny thing is that it was really seen that it would be possible to combine these basic ATCGs of DNA to create things designed with the mind in mind.
Paul's discovery ushered in a new direction. Scientists began working with DNA to create nanorobots. Now to make a real nanorobot you have to make something three-dimensional with it, not just draw on something. A few years later, William Shih succeeded in creating a variety of three-dimensional objects. This proves that it will be possible to make nano-sized things with DNA. So far with DNA that could only be amplified side by side, it was a really impossible thing to bend that William's team made possible.
Mark Bathe of MIT University in the US also created fun software that can easily design nano-sized objects with DNA. The name of the software he invented is CaDNAno and it is open-source software. You can use it to design anything you want in nano size, then send that design to a company so they can make your desired thing with DNA.
In the near future, it may be possible to make these nanorobots with DNA. Scientists hope that nanorobots can be used to cure cancer in the future. Nanorobots can easily detect and destroy cancer cells with their DNA.
Not only can nano-sized objects be designed with DNA in mind, but it is also possible to use this DNA as a data center for robots. Not only DNA but also proteins are being designed to make nanorobots. It is truly amazing to create robots using all these organic substances in the natural world as materials. But it seems that the day is not far away when you go to the hospital, the doctor will no longer have the medicine, he will inject nanorobots into your blood and it will reach your affected area and solve your problem.
