Blinking eye-on-a-chip used for disease modeling and drug testing

The latest iteration of an eye-on-a-chip has a mechanical eyelid to simulate blinking and was used to test an experimental drug for dry eye disease. By incorporating human cells into an engineered scaffolding, the eye-on-a-chip has many of the benefits of testing on living subjects, while minimizing risks and ethical concerns.
