Microfluidics

Definition

Microfluidics is the study and manipulation of fluids at the microscale, typically involving channels with dimensions in the range of tens to hundreds of micrometers. This technology allows for precise control over fluid flow and reactions, enabling the development of advanced devices for applications like biological analysis, drug delivery, and tissue engineering. In particular, microfluidics can significantly enhance the performance and efficiency of scaffolds and bioreactors by allowing for better nutrient delivery, waste removal, and controlled environments for cell growth.
