3D printed microrobots controlled by light – Towards environmental and biomedical applications

Microrobots are rapidly developing as a valuable solution for performing microscale tasks, among which they seem particularly promising for biomedical and environmental applications. Two-photon polymerization enables the fabrication of microstructures with complex shapes, while focused laser beams allow for precise manipulation of such 3D printed objects. Whereas several challenges have yet to be overcome before microrobots can perform in the real world, many interesting laboratory applications have already been demonstrated, while others are being explored
