摘要

具有多用途机械运动的磁性微型机器人将使许多体外和体内应用成为可能。不幸的是,由于制造吞吐量、器件占地面积和材料选择之间的折衷,在流线型微型机器人体内集成多种功能仍然具有挑战性。在这次演讲中,我将介绍一个用于微机器人功能化的统一框架架构,以实现磁操纵运动,化学传感和体内跟踪。这是通过在水凝胶微盘中分层刺激响应纳米颗粒来实现的。我们揭示了利用空间交变磁能势来控制欧拉圆盘状微型机器人在其侧壁上快速移动的关键机制。结果表明,微型机器人在移动的同时具有广泛的功能,适合通用应用场景,具有很大的潜力。

Rotating Micromachines with Stratified Disk Architecture for Dynamic Bioanalysis
Magnetic microrobots with versatile mechanical motion will enable many ex- and in vivo applications. Unfortunately, monolithic integration of multiple functions in a streamlined microrobotic body is still challenging due to the compromise between fabrication throughput, device footprints, and material choices. In this talk, I will present a unified framework architecture for microrobotic functionalization to enable magnetically steered locomotion, chemical sensing and in vivo tracking. This has been achieved through stratifying stimuli-responsive nanoparticles in a hydrogelmicro-disk. We uncovered the key mechanism of leveraging spatially alternating magnetic energy potential to control a Euler’s disk-like microrobot to locomote swiftly on its sidewall. The results suggest great potential for microrobots to locomote while cooperating a wide range of functions, tailorable for universal application scenarios.
