Magical Technology - Hydrogel Microrobots Ejecting PDA/N-P Microbubbles

These synthetic microrobots are either in a pure glycerol solution or in some oviduct fluid. It gets its propulsion force from NIR light irradiation. No fuel required. Also called self‐adaptive artificial microswimmers. Bioengineered to have a particle size of 200-300 µm.
