A new biomaterial that closely replicates the mechanical properties of human tissue has been developed by nanoengineers at University of California-San Diego.
This new material has promising potential as a repair tissue for damaged heart walls, blood vessels, and skin. This is because it has a negative Poisson's ratio, which means that even when it is stretched, it does not wrinkle.
AdvertisementThe new material is shaped like a "reentrant honeycomb" and "cut missing rib" unlike already available biomaterials, which are shaped like circular holes. The latter pattern acts as a scaffold.
Shaochen Chen, professor in the Department of NanoEngineering at the UC San Diego Jacobs School of Engineering, led the team that developed this material. The findings of this research effort appear in the journal Advanced Functional Materials.
