“…In addition to the examples shown in Figure 5, researchers have been exploring a number of different applications for light‐powered hard polymeric microrobots. In recent years, microrobotic waveguides, [ 114 ] microrobots with a segment covered by silver nanoparticles for surface‐enhanced Raman scattering studies, [ 83 ] microrobotic microsnap fits for cantilevers, [ 107 ] and microrobotic dumbbells for fluid viscosity characterization [ 115 ] were reported.…”

“…3D-printed polymeric microrobots controlled by focused light beams have been around for nearly two decades. [2] A plurality of commercial acrylic or epoxy-based negative photoresists, [85,87,[103][104][105][106] as well as the hybrid organic-inorganic material Ormocomp, [107] are used for 2PP DLW of hard polymeric microrobots. The hard polymeric microrobots covered by this section do not exhibit any shape-morphing properties, and instead their shape is defined during the fabrication process and remains unchanged during actuation.…”

Microrobots In article number http://doi.wiley.com/10.1002/aisy.202000256, Ada‐Ioana Bunea and co‐workers provide a critical overview of how microrobots can be manufactured and manipulated using light. The cover image shows blue structures printed in hard polymer and precisely manipulated by optical trapping with focused near‐infrared light, together with orange structures printed using soft, light‐responsive materials, which change shape in response to green light.
