A team of University of Glasgow researchers has worked to improve the imaging provided by swallowable cameras used to detect cancers in the throat and gut. The new video pills are able to emit fluorescent light, allowing the researchers to better analyze the returned imagery.
Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene at a fraction of the cost of current methods.
