that exploits resonance Raman enhancement to enable sensitive, highly multiplexed biological imaging. Here, we developed cyano-Hydrol Green (CN-HG) derivatives as resonance Raman scaffolds to expand the color palette of 9-cyanopyronins. CN-HG derivatives exhibit sufficiently long wavelength absorption to produce strong resonance Raman enhancement for near-infrared (NIR) excitation, and their nitrile peaks
9-cyanopyronin 是一种很有前途的支架,它利用共振拉曼增强来实现灵敏、高度多重的生物成像。在这里,我们开发了氰基-羟基绿 (CN-HG) 衍生物作为共振拉曼支架,以扩展 9-氰基吡咯宁的调色板。 CN-HG 衍生物表现出足够长的波长吸收,可产生近红外 (NIR) 激发的强共振拉曼增强,并且它们的腈峰移动到比 9-氰基吡咯宁更低的频率。与派洛宁衍生物不同,CN-HG衍生物的荧光由于缺少第10个原子而被强烈猝灭,这使我们能够检测具有高信噪比的自发拉曼光谱。 CN-HG 衍生物是高性能振动成像的有力候选者。
