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.
