Microfluidics

Definition

Microfluidics is the science of manipulating and controlling fluids at the microscale, typically within channels that are tens to hundreds of micrometers in width. This technology enables precise handling of small volumes of liquids, making it essential for various applications, including diagnostic testing, drug delivery, and biological analysis. Its integration into point-of-care testing devices allows for rapid, accurate diagnostics at the location of patient care.
