This analyte concentration measuring method including:
preparing a mixed solution by mixing a sample solution containing an analyte, with a solution containing aggregation-induced emission fluorescent material-containing particles that have a binding partner which binds with the analyte and that agglutinate and fluoresce when the analyte binds to the binding partner;
measuring the fluorescence intensity generated from the aggregation-induced emission fluorescent material-containing particles in the mixed solution; and
comparing a fluorescence intensity calibration curve for analyte concentration with the fluorescence intensity, and associating the fluorescence intensity with the analyte concentration in the mixed solution. Employing agglutinating-luminescent-material-containing particles enables measurements to be carried out with a satisfactory detection sensitivity while suppressing background fluorescence.
这种分析物浓度测量方法包括
制备混合溶液,将含有被分析物的样品溶液与含有聚集诱导发射荧光材料的颗粒的溶液混合,该颗粒具有与被分析物结合的结合伴侣,当被分析物与结合伴侣结合时,该颗粒会凝集并发出荧光;
测量混合溶液中含有聚集诱导发射荧光材料的颗粒产生的荧光强度;以及
将分析物浓度的荧光强度校准曲线与荧光强度进行比较,并将荧光强度与混合溶液中的分析物浓度联系起来。使用含凝集发光材料的颗粒可以在抑制本底荧光的同时,以令人满意的检测灵敏度进行测量。
