Abstract
Light-responsive micromotors using photosensitizer-decorated upconversion nanoparticles (UCNPs) are described. The UCNP motors converting near-infrared light into visible emission were propelled by oxygen bubble propulsion. The micromotor can be easily controlled by adjusting the light intensity, solution pH, and concentration of HO and UCNPs.
摘要
介绍了使用敏化剂修饰的上转换纳米粒子（UCNPs）的光响应微型马达。UCNP 马达将近红外光转化为可见发射，通过氧气泡推进来驱动。通过调节光强度、溶液 pH 值以及 HO 和 UCNPs 的浓度，可以轻松控制微型马达。
