Nanobots or nanorobots are microscopic robots that are expected to do specific tasks at the atomic, molecular and cellular level. Their prominence is in the field of medical science thanks to their immense potential.

Developers have long been intending to develop a robot that can fit into capillaries. Engineers in Switzerland have built a nanobot that has the capability of moving through blood vessels. It has a special shell that is filled with polymer mesh and, in place of sensors, the effect and the reactions of magnetic nanoparticles was used by developers during a change in the fields of electricity.

Moreover, the nanobot is capable of changing its shape, size, and direction of movement according to the condition.

According to Selman Sakar, the head of scientists, the principles of the Japanese kirigammi, the art of making paper figures with scissors, was applied by his team so that the nanobot would achieve the flexibility needed to move even in the narrowest of blood vessels.

Although the nanobot has passed all the necessary tests, improvements have to be made in design. Furthermore, this innovation is relatively cheap and can be easily availed by most people.
