Portable "tricorder" scans life signs

Scientists from the School of Engineering at the University of Glasgow have developed a handheld device for taking medical readings from patients, and transferring the data to a smartphone.

Building miniature optical antennas using DNA as a guide

An international research collaborative has reported a new, highly parallel technique to fabricate precise metallic nanostructures with designed plasmonic properties by means of self-assembled DNA origami shapes. The so-called ...

A nanotransistor made of graphene nanoribbons

Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the nanoelectronics of the future. While graphene, a one-dimensional ...
