Colorimetric inspection 

METAPLE BIO plays an important role in colorimetric inspection which can successfully determine the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent (ZCO, the name of the colorimetric inspection system manufactured by METAPLE BIO). 

ZCO is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.

Currently METAPLE BIO successfully realized a non-invasive glucose measurement system based on the ZCO. The color reaction measured by the ZCO is preceded by a reaction of nanoparticle catalyzed by glucose
