A Smartphone-Based Silver Nanoparticle Assay for Detecting Enhanced Gamma-Aminobutyric Acid Content in Germinated Rice via Metabolic Modulation

Abstract This study aimed to increase the γ-aminobutyric acid (GABA) content in rice grains and develop surface-modified silver nanoparticles (AgNPs) as a simple colorimetric chemosensor for its detection. To stimulate GABA production, rice grains from the Kor Kho 6 (RD6) and Kha...
