Introduction
Lab-on-a-Chip (LOC) systems have traditionally relied on predefined protocols and fixed control logic to perform microfluidic operations and biological assays. While these systems significantly improved efficiency and miniaturization, their performance remained constrained by limited adaptability and manual oversight.
The integration of Artificial Intelligence (AI) marks a fundamental shift in LOC technology—from automated execution to intelligent, adaptive, and self-optimizing systems. AI enables LOC platforms to interpret complex biological data, predict outcomes, and dynamically adjust system behavior in real time.
