Abstract
Creation of a flavylium polymethine dye set enabled selection of two fluorophores that match common lasers for exciting in the near-IR II region. Using these, researchers cast a broad net to catch any wavelength emission in the near-IR II region, and relied on selective to multiplex; this is a paradigm shift away from multiplexing via discrimination of wavelengths. Excitation multiplexing with flavylium dyes is a new and exciting strategy, but not yet a perfect one; it requires discrete water soluble fluorophores, including one that is turned on at 808 nm.
摘要
黄酮鎓聚甲炔染料组的创建使得能够选择两种与常见激光器匹配的荧光团，用于在近红外II区域进行激发。利用这些荧光团，研究人员撒下了一张大网，以捕捉近红外II区域的任何波长发射，并依靠选择性进行多路复用；这是一种从通过区分波长进行多路复用的范式转变。用黄酮鎓染料进行激发多路复用是一种新的、令人兴奋的策略，但还不是一个完美的策略；它需要离散的水溶性荧光团，包括一种在808nm处开启的荧光团。
