Microbead-Based Colorimetric and Portable Sensors for Polyphenol Detection.

ABSTRACT: Natural polyphenols found in health supplements and drinks have antioxidant and anti-inflammatory properties. In particular, to determine the beneficial qualities of antioxidant drinks and beverages, consumers demand precise quantification of the total amount of polyphenols as on-site detection. Herein, we developed a new concept of portable beads suitable for the field detection available: colorimetric quantification of polyphenols equipped with color converting software applications in a smartphone or tablet PC. The yellowish beads contain ferric ions to react with polyphenol to produce blackish metal-phenolic complexes. It is simple to perform the detection procedure: dipping the beads in the analytical sample and out-taking a photo-converting into RGB color values and quantification of
