carrageenan-based colorimetric sensor for total antioxidant

Carrageenan-based colorimetric sensor for total antioxidant

In this regard, a novel biopolymer-based colorimetric sensor was designed for total antioxidant capacity (TAC) assessment. Carrageenan polysaccharide was chosen as a building brick of the prepared biopolymeric film. Owing to the anionic sulfate groups of the carrageenan biopolymer, the film exhibited cation exchange properties.

The CUPRAC-paper microzone plates as a simple and rapid

For developing the colorimetric antioxidant sensor, the reagent was immobilized onto the surface of solid support films, such as Nafion, polymethacrylate, or carrageenan. While these films have different physicochemical properties from that of paper, the concentration of each component of CUPRAC reagent has to be optimized.
