fluorescent probe (RBLS) based on rhodamine derivatives was synthesized for the transient detection of mercury ions. The closed-on structure can realize reversible sensor recovery by adding S2-. The superior imaging capability in living cells and in vivo in zebrafish holds promise for biological applications. In addition, the naked eye test strips prepared with RBLS probes can be used to detect and screen Hg2+
荧光成像技术凭借其优势迅速发展,而近红外探针因其背景干扰少、光损伤小、潜力无限等特点值得关注。罗丹明及其衍生物具有独特的内酰胺螺旋结构,是构建开关荧光传感器的理想平台。本文合成了一种基于罗丹明衍生物的新型近红外荧光探针( RBLS ),用于汞离子的瞬时检测。该封闭式结构可以通过添加S 2-来实现可逆的传感器恢复。斑马鱼活细胞和体内的卓越成像能力为生物应用带来了希望。此外,用RBLS探针制备的裸眼试纸条可用于环境中Hg 2+的检测和筛查,并表现出良好的梯度变化性能。
