Organ-on-a-Chip technology is an innovative approach that mimics the functions of human organs using tiny, engineered devices. These chips are made from flexible materials and contain living cells that replicate the structure and behavior of specific organs, such as the heart, liver, or lungs. This technology allows researchers to study diseases, drug responses, and toxicology in a controlled environment, providing insights that traditional methods cannot. By using Organ-on-a-Chip systems, scientists can reduce the need for animal testing and improve the accuracy of their findings. This technology has the potential to revolutionize pharmaceutical research and development, leading to safer and more effective treatments for various medical conditions.
