Organ-on-a-chip

Definition

An organ-on-a-chip is a microfluidic device that simulates the functions of an organ or tissue by integrating living cells within a controlled environment. This technology mimics the physiological conditions of human organs, enabling researchers to study drug interactions, disease mechanisms, and organ responses in real-time without the need for animal models. By providing a more accurate representation of human biology, these devices hold great promise for personalized medicine and drug development.
