Microfluidics

Definition

Microfluidics is the science of manipulating and controlling fluids at the microliter or nanoliter scale, often using channels that are tens to hundreds of micrometers wide. This technology allows for precise control over fluid movement, mixing, and reactions, making it essential in various applications like drug delivery, diagnostics, and lab-on-a-chip devices. By integrating microfluidics with other technologies such as bioprinting and cell culture methods, researchers can create complex biological environments for studying cellular behavior and tissue engineering.
