Multi-organ-on-a-chip

Definition

A multi-organ-on-a-chip is an advanced microfluidic device that mimics the interactions and functions of multiple human organs on a single chip. This technology enables researchers to study how different organs communicate and respond to various stimuli, such as drugs or toxins, providing a more holistic view of biological processes. By recreating the physiological conditions of human tissues, it serves as a powerful tool for applications in drug discovery and toxicology.
