Organ-on-a-chip technology involves creating miniature models of human organs on microfluidic devices in order to mimic the structure and function of actual organs. This technology aims to provide more accurate and efficient platforms for drug testing, disease modeling, and personalized medicine. Organ-on-a-chip devices can simulate the complex biological processes and interactions that occur within human organs, allowing researchers to study physiological responses in a controlled environment. This area of research holds great potential for advancing the field of biomedicine and drug development.
