An organ-on-a-chip is a microfluidic device that simulates the functions of a human organ, allowing for the study of biological processes and disease mechanisms in a controlled environment. These devices integrate living cells and biomaterials to replicate the microarchitecture and physiology of actual organs, providing a valuable tool for drug testing and personalized medicine. They represent a significant advancement in biotechnology, merging engineering with biological sciences to offer insights into organ function without the need for animal models.
