- Here, we introduce a plant-inspired controllable micro-snap fastener for the remote release of objects at the microscale. The devices consist of two complementary parts, an "active hooked part" (realized with an array of Rosa arvensis- like microspines), and a "passive looped part". They were microfabricated at high resolution using two-photon lithography directly, or in combination with micro moulding and casting of thermoplastic polycaprolactone with incorporated gold nanoparticles (PCL@Au NPs). The microfabricated PCL@Au NPs-based microspines enable remote, near infrared laser-controlled stiffness variation (hard/soft) using a reversible phase transition of the PCL by plasmonic heating of the Au NPs. Besides, the potentiality of a proof-of-concept untethered remotely controllable device for easily clasping and releasing objects is demonstrated. Our technology shows great potential for micromanipulation tasks in harsh scenarios, such as space environments.
