Abstract

Smartphone-based lateral flow assays enable accessible point-of-care diagnostics but suffer from limited quantitative reliability. To address this limitation, this work introduces a lateral flow device with embedded gradient nanoparticle lines for on-strip optical calibration. The calibration gradient enables direct normalization of test signals at the time of image acquisition. A custom smartphone-supported web application performs automatic image recognition and signal processing. The proposed approach supports customizable quantitative healthcare and drug tests at low-cost without external optical accessories.
