Microfluidic bioreactor

Definition

A microfluidic bioreactor is a small-scale device that manipulates and controls fluid flows in a network of micro-channels to create specific environments for the growth and study of cells and tissues. These bioreactors allow for precise control of parameters like temperature, pH, and nutrient supply, making them ideal for simulating the conditions of biological systems on a miniature scale. They are essential tools in research, providing insights into cellular behavior and drug responses while minimizing the use of resources.
