compartments in the dark, as exemplified by their retention in the interior of erythrocytes. Subsequent illumination drives the secretion of the bioactive species from red blood cells. Photorelease is triggered by wavelengths in the red, far-red, and near-IR regions, which can be pre-assigned by affixing a fluorophore with the desired excitation wavelength to the Cbl-bioagent conjugate. Pre-assigned wavelengths

生物试剂结合物被囚禁在黑暗中的脂质封闭的隔室内,以其在红细胞内部的滞留为例。随后的照明驱动了红细胞中
生物活性物质的分泌。光释放由红色,远红色和近红外区域中的波长触发,可以通过将具有所需激发波长的荧光团固定到Cbl-bioagent共轭物中来预先分配光。
