The same electrons that form images of atomic structures can also be used to move atoms in materials. This technique of single-atom manipulation is now able to achieve nearly perfect control over the movement of individual silicon impurity atoms within the lattice of graphene.
A multidisciplinary team has developed a high-tech fix that utilizes metal nanostructures to increase the fluorescence intensity by 100 times in these diagnostic tests. It's a cheap and easy solution to what has previously been a vexing diagnostic problem.
EFSA has published its guidance on how to assess the safety of nanoscience and nanotechnology applications. The guidance gives practical suggestions on the types of testing that are needed and the methods that can be applied.
