A novel dansyl-based fluorescent probe was synthesized and characterized. It exhibits high selectivity and sensitivity towards Fe(3+) ion. This fluorescent probe is photostable, water soluble and pH insensitive. The limit of detection is found to be 0.62 μM. These properties make it a good fluorescent probe for Fe(3+) ion detection in both chemical and biological systems. Spike recovery test confirms its practical application in tap water samples.
合成并表征了一种新型的丹磺酰基荧光探针。它对 Fe(3+)离子具有高选择性和高灵敏度。该荧光探针具有良好的光稳定性、水溶性和 pH 不敏感性。检测限被发现为 0.62 μM。这些性质使它成为化学和生物体系中检测 Fe(3+)离子的一种良好的荧光探针。加标回收试验证实了其在自来水中的实际应用。
