Scanometry as microplate reader for high throughput method based on DPPH dry reagent for antioxidant assay

The DPPH solution was immobilized on the microwell plate as dry reagent to construct colorimetric antioxidant sensor. A flatbed scanner was used as a microplate reader to obtain analytical parameters for antioxidant assay as scanometric technique. The sensor was optimized and applied for determining antioxidant capacity of plant extract samples.141
