water-soluble “turn-on” fluorescent probe (RD1) for Fe3+ based on rhodamine B was designed and synthesized. The fluorescent probe showed “turn-on” fluorescent and colorimetric responses to Fe3+ with a high selectivity in water containing less than 1% organic cosolvent. Furthermore, bioimaging investigations indicated that the new probe was cell permeable and suitable for monitoring intracellular Fe3+ in living
设计并合成了基于若丹明B的Fe 3+水溶性“开启”荧光探针(RD1)。荧光探针在含有少于1%的有机助溶剂的水中对Fe 3+表现出“开启”的荧光和比色响应,具有高选择性。此外,生物成像研究表明,该新探针具有细胞渗透性,适合通过低细胞毒性的共聚焦显微镜监测活细胞中的细胞内Fe 3+。
