A smartphone-integrated dual-mode nanosensor based on Fe3O4@Au for rapid and highly selective detection of glutathione
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy（2022）
Abstract
•The mimics enzymes that has the high catalytic activity of natural enzymes.•Fe3O4@Au exhibits enhanced intrinsic peroxidase-like activity.•The color changing of solution can be simply visualized by the naked eye.•RGB intensities were measured to quantify GSH concentration.•The on-site device for GSH determining based on smartphone and Fe3O4@Au was developed.
