Detecting Glucose Levels in Blood Plasma and Artificial Tear by Au(I) Complex on the Carbopol Polymer: A Microfluidic Paper-Based Method.

We report on a selective paper-based method and a microfluidic paper-based analytical device (μPAD) for the detection of human plasma glucose and tear glucose using carbopol polymer-encapsulated Au(I) complex (AuC₂C₆H₄OMe)₂(Ph₂P(C₆H₄)₃PPh₂), (). To the best of our knowledge, this demonstrates for the first time the glucose sensing based on dual emission, i.e.
