The video discusses the development of organs on a chip technology, which aims to mimic human tissues outside the body. This technology could revolutionize drug discovery by predicting toxicity and drug interactions more accurately than current methods. Challenges include obtaining functional cells and ensuring interconnectivity. The use of hydrogels and 3D environments helps create realistic tissue structures. The technology allows for testing drug responses on tissues from different individuals, potentially reducing the cost and time of drug development. The field is relatively new but holds significant promise for the pharmaceutical industry.
