It may sound strange, but scientistsat the University of California at San Diegoplanto inject medical "microfish" robots into patients' bloodstreams to hoover up toxins and administermedications internally. According to a report from Tech Crunch, researchers have devised a methodto 3D-print the tiny robots using a wide range ofmaterials that interact with their surroundings.

The robots are fitted withnanoparticles that can be used to directly insert chemicals into cells and tissues, which could changethe way doctors administer medicine to patients forever. The tails of the3Dprinted microbots are made ofnanoparticles includingplatinum that react with hydrogen peroxide in the blood, thrusting itforward. Thefront of the robot is also fitted withmagnetic iron oxide nanoparticles that steer the robots through the blood.

The invention could soonbecomea part of new-and-improved drug delivery systems. The tiny robots can remove toxins from water with polydiacetylene (PDA) nanoparticles, which bind totoxins similar to the ones found in bee's venom. The swimming fish robots locatedand neutralized toxins faster and more efficiently than other traditional chemical treatments.

The amazing tinyrobots can cover a significant amount of area with their chemical-powered swimming mechanisms, and could provide doctors with a new means of non-invasive drug delivery.It will be some time beforethe robots areready for widespread use,but many researchers are excited about the possibilities presented by the tiny fishbots.
