N2 - This paper describes an infrared (IR) light-responsive hydrogel micro-gripper for intravascular surgery. The hydrogel micro-gripper was fabricated by two-step photolithography that can design the motion of gripper. The gripping motion was controlled by IR exposure that was efficiently and selectively absorbed by the single walled carbon nanotubes (SWCNT) to generate heat. We confirmed the gripping speed in micro-scale gripper (width: sim 200 mumathrm{m}) was faster than that of the large scale (width: ∼2 mm). We demonstrated the hydrogel micro-gripper firmly gripped and kept holding a 200-mumathrm{m}-diameter bead with the chamber being shaken. We believe that our hydrogel micro-gripper can be applied for medical applications such as low-invasive medical practices because it could grip cells or foreign objects by being exposed to IR light irradiated from outside of the body.
