Manganese dioxide shows potential in micromotors
Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland. Synthetic micromotors are tiny particles with dimensions less than the diameter of a human hair. Micromotors can undergo an autonomous motion in liquid environments, which can be driven by various means such as a chemical fuel, ultrasound, light or magnetic field. Fuel-driven micromotors are often catalytic in nature, which causes the transformation of a chemical fuel into reaction products that
