Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device ...

Carbon nanotubes (CNT) have been under intense study by scientists all over the world for more than a decade and are being thought of as ideal building blocks for nanoelectromechanical systems.

Now scientists from Northwestern University have demonstrated a novel carbon nanotube-based nanoelectromechanical switch exhibiting bistability based on current tunneling. The device could help ...

A new study examines the agn43 epigenetic switch of Escherichia coli, providing an alternative to feedback regulation as a model for gene expression regulation. Through a combination of synthetic ...

Bistable structures in nature are unparalleled for their fast response and force amplification even with the minutest physical stimulation. Harnessing bistability and instability to rapidly release ...
