Abstract
The delivery of NO at a high spatiotemporal precision is important but still challenging for existing NO-releasing platforms due to the lack of precise motion control and limited biomedical functions. In this work, we propose an alternative strategy for developing the light-armed nitric oxide-releasing micromotor (LaNorM), in which a main light beam was employed to navigate the microparticle and stimulate NO release and an auxiliary light beam was used to cooperate with the released NO to act as a remotely controlled scalpel for cell separation. Benefiting from the advantages of fully controlled locomotion, photostimulated NO release, and microsurgery ability at the single-cell level, the proposed LaNorM could enable a series of biomedical applications in vivo, including the separation of flowing emboli, selective removal of a specific thrombus, and inhibition of thrombus growth, which may provide new insight into the precise delivery of NO and the treatment of cardiovascular diseases.
高时空精度地释放一氧化氮非常重要,但由于缺乏精确的运动控制和有限的生物医学功能,现有的一氧化氮释放平台仍面临挑战。在这项工作中,我们提出了开发光臂一氧化氮释放微马达(LaNorM)的另一种策略,即利用主光束导航微粒子并刺激一氧化氮释放,同时利用辅助光束与释放的一氧化氮配合,充当细胞分离的遥控手术刀。由于具有完全可控运动、光刺激 NO 释放和单细胞水平显微手术能力等优点,拟议的 LaNorM 可在体内实现一系列生物医学应用,包括分离流动的栓子、选择性清除特定血栓和抑制血栓生长,从而为精确输送 NO 和治疗心血管疾病提供新的思路。
