  for fluorescent labeling of biomolecules is presented by examples on model frameworks representing major biopolymer building blocks. The versatility of these dyes is presented in cell labeling experiments as well as by labeling the azide modified surface glycans of CHO-cells either by copper catalyzed or copper-free click reaction. These dyes are expected to have a large variety of applications in (bio)orthogonal

  The development of fluorescent probes for sensing of anions in biological environments is still a demanding task. Due to the structural versatility of biological active anions there are many challenges to cope with compared to fluoroionophores for the determination of metal cations. This concerns particularly the design of the recognition element, which has to provide a selective response, preferably unaffected by alterations of pH and ionic strength. Polyphosphate anions such as ATP are interesting targets in bioanalysis because they are involved in many enzymatic reactions and bear versatile biological functions. Zinc dipicolylamine complexes attached to fluorophores have been turned out to be promising candidates for ATP sensing with sufficient sensitivity and selectivity. We now report the first NIR probe that responds to ATP based on a zinc dipicolylethylenediamine receptor. It shows a “turn-on” fluorescence behavior which is selective to other polyphosphate species even at high ionic strength of the sample solution.

  开发用于感应生物环境中阴离子的荧光探针仍然是一项艰巨的任务。由于生物活性阴离子的结构多变，与测定金属阳离子的荧光探针相比，需要应对许多挑战。这尤其涉及识别元件的设计，它必须提供选择性反应，最好不受 pH 值和离子强度变化的影响。多磷酸盐阴离子（如 ATP）是生物分析中的有趣目标，因为它们参与了许多酶促反应，具有多种生物功能。附着荧光团的锌二羟胺复合物已被证明是具有足够灵敏度和选择性的 ATP 感测的理想候选物。现在，我们报告了首个基于二烷基乙二胺锌受体的 ATP 近红外探针。它显示出一种 "开启 "荧光行为，即使在样品溶液离子强度较高的情况下，也能对其他多磷酸盐物种产生选择性。
