A rational design has led to a highly selective and cell-permeable zinc sensor, which exhibits not only a large fluorescence turn-on at ∼545 nm but also the desirable NIR emission (∼720 nm) with a large Stokes' shift, providing a practical sensor platform with two emission channels for reliable zinc detection.
该传感器不仅在 ∼545 nm 处有较大的荧光开启,而且还具有理想的近红外发射(∼720 nm)和较大的斯托克斯偏移,为可靠的
锌检测提供了一个具有两个发射通道的实用传感器平台。
