Drug testing in the United States is both time-consuming and costly. In response, scientists are pioneering the development of small silicon computer chips designed to replicate human organs. These chips, part of the Tissue Chip for Drug Screening Program led by the US National Center for Advancing Translational Sciences (NCATS), aim to streamline and economize the drug development process.

These miniature chips, smaller than a child's hand, contain living cells that mimic the behavior of various human organs. For instance, there are three-dimensional chips emulating the functions of a human lung, while others replicate the complexities of the digestive system. Introducing drugs to these tiny organs is facilitated through micro-tubes.

Notably, experiments utilizing tissue chips have yielded more intricate insights compared to traditional methods involving animal or cell models. Researchers can safely assess a drug's impact on different organ systems, offering a comprehensive view of its effects before human trials commence.
