Simultaneous detection of trace protein biomarkers from a single drop of blood using AI-enhanced smartphone-based digital microscopy.

The detection of early-stage diseases is often impeded by the low concentrations of protein biomarkers, necessitating sophisticated and costly technologies. In response, we have developed an advanced cyber-physical system that integrates blood plasma separation, biomarker detection, and analysis on a single microfluidic platform. This novel system enables the simultaneous detection of Neuron-Specific Enolase (NSE) and Carcinoembryonic Antigen (CEA) with high specificity and accuracy.
