Microfluidics

Definition

Microfluidics is the science and technology of manipulating and controlling fluids at the microliter to picoliter scale, often using channels that are only a few micrometers wide. This field allows for precise control of fluid flow, enabling various applications such as biochemical analysis, drug delivery, and the development of biosensors. By integrating microfluidic systems with biosensors and chemical sensors, researchers can create compact and highly efficient devices that improve the speed and accuracy of chemical analysis.
