糖的分子识别和一种检测和区分大量类似分析物的实用方法仍然是重大的科学挑战。我们在这里报告了一种低成本,简单的比色传感器阵列,能够识别和定量糖和相关化合物。在80次试验中,15种不同的单糖、双糖和人工甜味剂被准确区分。在pH 7.4下,葡萄糖的检出限<1mM,低于生理上重要的水平。
Molecular recognition of sugars and a practical method to detect and discriminate among a large number of such similar analytes remain substantial scientific challenges. We report here a low-cost, simple colorimetric sensor array capable of identification and quantification of sugars and related compounds. Fifteen different monosaccharides, disaccharides, and artificial sweeteners were differentiated without error in 80 trials. Limits of detection at pH 7.4 for glucose were <1mM, which is below physiologically important levels.
