Nanotechnology

High-performance transistors based on silicon–germanium nanowires can be made using an approach compatible with existing mass-production techniques

The electronic properties of graphene ribbons are strongly dependent on the atomic structures at the ribbon’s edge

Custom-built antimicrobial peptides can cross the blood–brain barrier and destroy harmful bacteria and fungi

A sensor made from silicon nanowires could warn doctors when a patient is at risk of a heart attack

Theoretical studies suggest that silicon nanowires shorter than 3 nm lose their intrinsic electronic characteristics when incorporated between metal electrodes
