Liver Chip

Liver failure causes many people to die each year, so Linda Griffith, a tissue engineer, and her research team are trying "physiological models" to help them understand liver diseases. They way they have done this is by inplanting a miniture liver on a chip, smaller than dime, to a circulation system in order to observe the cells and understand what is happening in the tissue as time passes. Hopefully this "liver on a chip" as it is called which is made up of silicon, will help with developing drugs for liver disease.
