Introduction
Personalized medicine aims to tailor medical treatment to individual patients based on their genetic makeup, biological characteristics, and real-time health data. Traditional healthcare approaches often rely on generalized treatment protocols, which may not be optimal for every patient. Microfluidic systems, particularly when integrated into Lab-on-a-Chip (LOC) platforms, have emerged as powerful tools for enabling personalized medicine by allowing precise, rapid, and patient-specific analysis.
