With the emerging interest in optical in vivo imaging, there is an increasing demand of photostable near-infrared (NIR) dyes. Herein we report the rational design of an amine tricarbocyanine structure with improved photostability (CyNA) and its combinatorial derivatization to render CyNA-414 as a NIR-fluorescent dye with stronger emission intensity and higher photostability than the NIR standard IndoCyanine Green (ICG).
随着对光学体内成像的日益关注,对光稳定近红外(NIR)
染料的需求也在增加。本文报告了一种改进了光稳定性的胺三
氰染料结构(CyNA)的合理设计,以及其组合衍生化,最终得到CyNA-414,这是一种比近红外标志物
吲哚氰绿(ICG)具有更强发射强度和更高光稳定性的NIR荧光
染料。
