Hydrogen-Bubble-Powered Microrockets Could Deliver Drugs Directly Into Patient’s Bodies

Researchers have been designing a wide variety of self-propelled micromotors, many which operate using an oxygen-bubble propulsion mechanism that requires a high concentration of hydrogen peroxide as fuel, which in turn is hazardous at high concentrations, hindering its usefulness in biomedical applications. In a new study, scientists have created a new type of micromotor that can propel itself through acidic environments using only hydrogen bubbles. At low pH levels, the micromotors can travel at speeds of up to 100 body lengths per second, prompting the colloquial use of microrockets to designate these devices.
