Abstract
Silver-based materials show a great potential to be applied in sensors due to their optical, electronic, and chemical properties. In this work, we report the use of a zeolite framework modified with silver ions as a colorimetric sensing array for the detection of chlorogenic acid (CGA). The detection was done by digital image colorimetry (DIC) based technique integrated with a smartphone. Red, green, and blue (RGB) was able to monitor CGA in the range of 1 – 20 mg L-1. with the limit of detection (LOD) of 0.39 mg L-1.
