In the world of medicine, nanorobots or microbots have become the new frontier. These tiny robots are revolutionizing the medical field by shrinking to unprecedented sizes. With their potential to be delivered in large numbers through a single pill, they hold the promise of delivering life-saving medications to hard-to-reach areas of the body.

The engineers at the University of Colorado, Boulder have developed an impressive new class of self-propelled robots that can navigate through the body at incredible speeds. Made from biocompatible polymer materials using a technology similar to 3D printing, these bots resemble small rockets with three fins. They can move quickly at speeds equivalent to a six-foot-tall person running at 400 miles per hour.

While further testing is needed, the potential of these microbots is promising for transforming science fiction into reality. Currently, they exit the body through urine, but efforts are underway to make them completely biodegradable so they can dissolve inside the body after delivering their medication. This groundbreaking work has the potential to change the world of medicine in the future.

In conclusion, nanorobots or microbots are becoming smaller and more advanced than ever before. Their potential to deliver life-saving medications to hard-to-reach areas of the body is exciting and holds immense promise for transforming science fiction into reality. The engineers at UC Boulder have developed an impressive new class of self-propelled robots that could revolutionize medicine in years to come.
