How about having nano-robots walking inside your body?

Yeah you heard it, now it is real! Think about the Ant Man and his ability to shrinking himself to a micro level. In Pennsylvania University, under the leadership of Marc Miskin, a group of researchers developed the quadrupedal (4 legs) nano-robots which can walk inside the body through their targets. During these days, we are experiencing a number of exciting innovations designed for the examination and treatment processes. We have seen similar innovation such as; a microneedle insulin capsule, a handled ultrasound which is very user-friendly and a tattoo which shows the glucose level of the blood. Now we also have new nano-robots thanks to Pennsylvania University scholars.

70 Micron Sized ‘Giant’ Health Keepers

These handy health keepers are very genius that they can walk through their targeted destination. The robot is created by Assistant Prof. Marc Miskin at the University of Pennsylvania and it is still being developed with the contributions of Professors Itai Cohen and Paul McEuen and researcher Alejandro Cortese. 

Since they use the multi-step nano- fabrication production technique, it is possible to produce one million micro-robots in few weeks.For that amount of production 102 mm silicon composit plate is required. The body of these micro-robots consist of a rectangle shaped ultra-thin glass covered by a layer of silicon. Two or four solar cells are engraved on top of this layer with their electronic control components and the legs of the robots are made of a 100 atomic thick material which composed of a layer of platinum, lithium and titanium.

Injection with a needle is possible!


when laser beam is delivered to the solar panels it cause transformation of AC to the front and rear legs. This electric current causes the titanium to harden and the platinum to expand; so each leg is bent according to this principle. When the current is shut down, the legs turn back to the straight position. As the legs bent and flattened it allows nano-robots to move forward. And these little mates are so small that they can even inject with a needle to our body. For now, the robots are currently under the improvement process because they are able to operate under a nail thick skin layer. Because laser beams are not able to be delivered to the robots in deep layers. Assistant Prof. Marc Miskin still working on to find alternative power supplies such as ultrasound and magnetic fields.  Researchers from Pennsylvania and Cornell University are also contributing to the development of the robot; and they are working on smart versions with sensors, clocks and self-control.
