Flip-PAD integrating laser-scribed platinum-nanozyme for rapid smartphone-based colorimetric determination of ascorbic acid
AA dose-response signal resulted linear from 31 to 250 mg kg<sup>-1</sup> (R<sup>2</sup> = 0.992), showing a LOD of 6 mg kg<sup>-1</sup>; analytical performance resulted constant over 6 weeks (RSD = 4 %). The Flip-PAD exploitability was proved for the AA determination in different foods and pharmaceutical samples, returning accurate (recoveries 92-114 %; relative error -11/+4 %) and reproducible (RSD ≤10 %; n = 3) data. The proposed laser-based approach opens new paths for PADs and nanostructured systems development.
