摘要

合成 Janus 微型/纳米马达可以有效地将环境能量转化为不对称的自推动力,克服随机热波动,实现自主迁移。对电机的进一步改造可以为其配备不同的功能模块,以满足不同的需求。然而,为多功能 Janus 微电机开发一种多功能、高产量的制造方法仍然具有挑战性。本研究提出了一种基于二氧化钛微球阵列诱导的自聚焦光刻技术的颗粒尖端结构微电机模块化制造方法。通过调整尖端成分或装载量,可对电机功能进行精确编程,从而实现光氧化还原反应诱导推进、荧光成像、电导航和磁导航等多种功能。此外,还展示了这种制造方法的灵活性,即选择性地将材料装载到两个尖端,从而实现微电机单元的多功能性。这项研究为模块化功能微电机提出了一种直接而多用途的方法。

Modular Micromotor Fabrication with Self-Focusing Lithography.

Synthetic Janus micro/nanomotors can efficiently convert ambient energy into asymmetrical self-propulsive force, overcoming random thermal fluctuations and enabling autonomous migration. Further modifications to the motors can equip them with different functional modules to meet different needs. However, developing a versatile and high-yield fabrication method for multifunctional Janus micromotors remains challenging. In this study, a modular fabrication approach for micromotors with a particle-tip structure based on the self-focusing lithography induced by an array of TiO2 microspheres is presented. By adjusting the tip composition or loading, precise programming of motor functionality is achieved, allowing for various capabilities such as photoredox reaction-induced propulsion, fluorescent imaging, electric and magnetic navigation. Furthermore, the flexibility of this fabrication method by selectively loading materials onto two tips is demonstrated to achieve multifunctionality within a micromotor unit. This study proposes a straightforward and versatile approach for modular functional micromotors.
