Photoswitchable drugs are small-molecule optical probes that undergo chromatically selective control of drug efficacy using, most often, UV-visible light. Here we report that luminescence produced by near-infrared stimulation of NaYF4:TmYb nanoparticles can be used for "remote control" of an azobenzene-based photochromic ion channel blocker of neurons in living brain slices.
光致变色药物是小分子光学探针,最常用于使用紫外-可见光进行药物功效的色度选择性控制。在这里,我们报告说,通过近红外刺激 NaYF4:TmYb 纳米粒子产生的发光可用于“远程控制”基于偶氮苯的光致变色离子通道阻断剂对活脑切片中的神经元的作用。
