detection (LOD) for Hg2+ was 1.0 μM (202 ppb) and 11.8 nM (2.38 ppb), respectively. Further, the applicability of probe L in the determination of Hg2+ in various water samples and biological samples were tested. Human Bone Osteosarcoma cell lines (HOS) were utilized for this study and satisfying results were obtained. These cell line results also further support the ‘on-off’ properties of probe L. Based
我们开发了一种基于
苯并噻唑与
丙烯酸喹啉酯共轭的新型显色荧光
化学传感器( L ),用于检测Hg 2+离子,具有优异的选择性和灵敏度。在Hg 2+的存在下, L的荧光从淡蓝色淬灭到无色。L可以在 5.0–8.0 的宽 pH 范围内工作,而不会受到其他测试离子的相当大的干扰。紫外可见和荧光研究表明,Hg 2+的检测限 (LOD) 分别为1.0 μM (202 ppb) 和 11.8 nM (2.38 ppb)。此外,探针L在测定 Hg 2+中的适用性在各种
水样和
生物样品中进行了测试。人骨骨肉瘤
细胞系 (HOS) 用于本研究并获得了令人满意的结果。这些
细胞系结果也进一步支持探针L的“开关”特性。基于比色和荧光结果,我们为未来应用设计了一个布尔逻辑门。
