Organ-on-a-Chip is a cutting-edge technology that mimics the functions of human organs on a small chip. These chips are made from flexible materials and contain tiny channels that simulate blood flow, allowing researchers to study how organs respond to drugs, toxins, and diseases in a controlled environment. This innovative approach helps scientists gain insights into human biology without relying solely on animal testing. By replicating the microenvironment of organs like the heart, liver, or lungs, Organ-on-a-Chip can improve the accuracy of medical research and accelerate the development of new treatments.
