Introduction
Early disease detection is one of the most effective strategies for improving patient outcomes, reducing healthcare costs, and enabling timely intervention. Many genetic and molecular diseases exhibit subtle biological changes long before clinical symptoms appear. Detecting these early biomarkers using conventional laboratory methods is often challenging due to low signal intensity, biological variability, and delayed testing cycles.
The integration of Artificial Intelligence (AI) with Lab-on-a-Chip (LOC) devices provides a powerful platform for early disease detection. LOC systems enable rapid, miniaturized analysis of patient samples, while AI algorithms enhance sensitivity, identify early pathological patterns, and support real-time diagnostic decisions. This topic explores how AI-driven LOC devices are transforming early disease detection in modern healthcare.
