Doctoral candidate Marina Pilz Da Cunha (IMAGE) Eindhoven University of Technology Caption Doctoral candidate Marina Pilz Da Cunha from Eindhoven University of Technology developed a tiny plastic robot, made of responsive polymers, which moves under the influence of light and magnetism. In the future this ‘wireless aquatic polyp’ should be able to attract and capture contaminant particles from the surrounding liquid or pick up and transport cells for analysis in diagnostic devices.
