4D–Printed Photothermally Actuated Soft Microgripper on an Optical Fiber Tip for Biomedical Applications

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...
