合成了一种七甲基菁- bapta缀合物，在782 nm处发射强度增加了近4倍，表明钙结合。这一显著的增强因子为红外荧光化学传感器的开发开辟了新的可能性，该传感器可由廉价的780纳米激光二极管激发，并可由高灵敏度的雪崩二极管检测。(C) 2000 Elsevier Science Ltd.版权所有。
A heptamethine cyanine-BAPTA conjugate was synthesized which signals calcium binding by an almost 4-fold increase in the emission intensity at the emission maximum of 782 nm. This significant enhancement factor opens new possibilities for the development of IR fluorescent chemosensors excitable with an inexpensive 780 nm laser diode and detectable with highly sensitive avalanche diodes.
