摘要

研制了一种高选择性、高灵敏度的双光子近红外荧光开启传感器，用于检测Zn2+。该传感器具有较大的斯托克斯位移(~ 300 nm)，可以在900 ~ 1000 nm范围内激发，发射波长为~ 785 nm，使其成为生物组织成像的理想选择。该传感器对Zn2+的高选择性优于其他结构相似的阳离子，如Cd2+，使其成为监测生物系统中锌离子水平的有前途的工具。鉴于血栓中锌的高浓度，该传感器可以为血栓的体内成像提供有用的工具。

An Enviromentally Sensitive Zinc-Selective Two-Photon NIR Fluorescent Turn-on probe And Zinc sensing In Stroke

A two-photon near infrared (NIR) fluorescence turn-on sensor with high selectivity and sensitivity for Zn²⁺ detection has been developed. This sensor exhibits a large Stokes' shift (∼300 nm) and can be excited from 900 to 1000 nm, with an emission wavelength of ∼785 nm, making it ideal for imaging in biological tissues. The sensor's high selectivity for Zn²⁺ over other structurally similar cations, such as Cd²⁺, makes it a promising tool for monitoring zinc ion levels in biological systems. Given the high concentration of zinc in thrombi, this sensor could provide a useful tool for in vivo thrombus imaging.
