A team of scientists is developing a micro fish through the 3D printing technology capable of developing drugs inside the human body.

The team created a microfish using the 3D printing technology that has various functions like sensors, detoxification, directed drug delivery and much more. Experts believe that this could advance expertise in medical field. The team created the fish with complex mechanisms for movement, including microjetenginers, microdrillers and microrockets using the advanced 3D printing technology.

They said that the new microfish is better than previous simpler microbot locomotion methods. They said that most existing microrobots are not capable of perming complex and sophisticated tasks due to their simple structures but microfish will come with a host of capabilities. Nanoengineers worked to install platinum nanoparticles in the tails of the fish that react with hydrogen peroxide to propel them forward. They also embedded magnetic iron oxide nanoparticles allowing the microfish to be steered with magnets.

Co-author Wei Zhu, a nanoengineering Ph. D. student in research group, said, "We have developed an entirely new method to engineer nature-inspired microscopic swimmers that have complex geometric structures and are smaller than the width of a human hair"

The team mixed polydiacetylene (PDA) nanoparticles that are capable of capturing harmful pore-forming toxins. When PDA captures toxins, it glows fluorescent and emits red light allowing researchers to know the efficiency of treatment. The team said that the new robot can both sense toxins and work as detoxifying robots.
