In this study, a sensor system was designed to detect metal ions based on the fluorescence resonance energy transfer (FRET) process between free‐phthalocyanine (PC) and merocyanine 540 (MC540). Following the determination of parameters and appropriate conditions for energy transfer, the sensor system was tested with different metal ions. The conclusion was that the system showed high selectivity to iron and aluminum ions. In this FRET system, limit of detection (LOD) values for metal ions were calculated as 437 nM for Al³⁺ and 32.1 nM for Fe³⁺. The system was able to detect iron and aluminum in very low concentrations. It also showed good selectivity for the two metal ions.

酞菁-花菁540染料基荧光共振能量转移检测Al3 +和Fe3 +离子

在这项研究中，基于游离酞菁（PC）和部花菁540（MC540）之间的荧光共振能量转移（FRET）过程，设计了一种传感器系统来检测金属离子。在确定参数和合适的能量转移条件之后，使用不同的金属离子对传感器系统进行了测试。结论是该系统显示出对铁和铝离子的高选择性。在此FRET系统中，金属离子的检出限（LOD）值计算为Al ³⁺为437 nM，Fe ³⁺为32.1 nM 。该系统能够检测极低浓度的铁和铝。它还显示出对两种金属离子的良好选择性。
