Covalently functionalized nanotubes as nanometre-sized probes in chemistry and biology
Article Abstract:
Carbon nanotubes have a range of properties which are suitable for use in applications such as atomic force microscopy. They are able to buckle elastically, which makes them strong whilst restricting the maximum force applied to delicate organic and biological samples. Nanotube tips able to chemically and biologically discriminate can be developed with acidic functionality by coupling basic or hydrophobic functionalities. Such modified nanotubes have been used as AFM tips to image patterned samples.

A quantum leap for electronics
Article Abstract:
There is hope that electronic devices can be shrunk to single-atom or molecule scale with recent advances in nanofabrication. Sheer and colleagues have described the electrical measurements on single metal atoms and have shown that conductivity relies on the number of valence orbitals available. They have shown that single-atom devices can be produced by lithography and have verified that conduction is strongly affected by the local electronic properties of single atoms.
