Polymer thin film-embedded metal oxide-modified electrochemical paper-based sensor for glycine detection

Year: 2025

Type: article

Abstract: -poly(l-glutamic acid) and cadmium oxide quantum dots was utilized for the detection of glycine. The proposed ePAS exhibited potential electrocatalytic activity toward the oxidation of glycine. The electrochemical studies showed a higher sensitivity for glycine in a basic medium in a potential window of -0.4 to +0.6 V. The detection limit for glycine under optimized conditions achieved with this sensor was 75.8 μM, while the limit of quantification was 229.7 μM. The sensor showed high sensitivity and reproducibility for up to 25 cycles and directly quantified the amino acids in the samples. The sensor could be reused, making it more economical and environmentally friendly.
