Researchers at Max Planck Institute for Intelligent Systems in Stuttgart, Germany, have developed two types of microswimmers:
1. microscallop
– 300 micron wide x 600 micron long
– open and close at different speeds (shear thickening) to move in non-Newtonian body fluids
2. nano propeller
– 100 nanometres wide x 400 nm long
– helical structure moves forward when rotating magnetic field applied
