representative fluorescent probes, targeting pH, cysteine, hydrogen sulfide, hydrogen peroxide, palladium and hydrazine, were synthesized and tested. Without utilizing costly instrumentations, portable devices were employed to collect data of photographs from the fluorescence samples in responses to different analytes. Subsequently, the photographic images were digitally processed to generate calibration curves
摘要利用荧光探针实现对分析物的定量分析,以实现一种快速,简便,精确的方法,是一个方便检测的目标,尤其是在原位。在本文中,我们报告了一种通常可用于通过荧光色度和发光度区分和定量分析物的方法。合成并测试了针对pH值,半胱氨酸,硫化氢,过氧化氢,钯和肼的七个代表性荧光探针。在不利用昂贵的仪器的情况下,采用便携式设备来响应不同的分析物而从荧光样品中收集照片数据。随后,在映射到CIE 1931 xyY标准色空间后,对照片图像进行数字处理以生成色度/发光度与浓度之间的校准曲线。良好的线性校准曲线和通过光谱技术对低误差的未知样品进行定量分析证明了该方法的可靠性。因此,我们展示了一种具有简单现场可构建/便携式设备的分析方法,有望在更多的荧光探针中应用
