Graphene in the Spotlight

January 25, 2013 – 4:28 pm

They should have called it graphenepalooza. The current MRS Bulletin from the Materials Research Society is entirely devoted to graphene, a single layer of carbon atoms arranged as a honeycomb-shaped lattice that has unique strength, conductivity and other properties. Several technical articles cover every aspect of the material, including its potential medical applications in biosensing and bioimaging.

Researchers from the Central China Normal University and Pacific Northwest University in the United States have penned an article discussing the immobilisation of enzymes, DNA and proteins on graphene materials as well as fluorescence biosensors based on the material. They also make note of the technical challenges that must be overcome if the material is to have widespread use for biosensing and bioimaging, notably the need for low-cost and simple methods for synthesising highly conductive graphene.

This article and, indeed, the entire issue can be viewed free of charge until 28 February 2013.
