Introduction
Lab-on-a-Chip (LOC) technology has transformed biological and medical research by miniaturizing complex laboratory processes into compact, automated systems. However, as LOC platforms grow in complexity—handling vast amounts of data, executing multi-step workflows, and supporting real-time decision-making—traditional control and analysis methods are becoming insufficient.
