Colorimetric Sensor Array for Soft Drink Analysis
Journal of Agricultural and Food Chemistry, 2006Fourteen commercial soft drinks have been analyzed using colorimetric sensor arrays made from a set of 25 chemically responsive dyes printed on a hydrophobic membrane. Digital imaging of the dye array before and after immersion provides a color change profile as a unique fingerprint for each specific analyte.
