New grant for research into peptide nanotubes
(Nanowerk News) Professor Dek Woolfson, Dr David Fermin and Dr Franziska Thomas in the School of Chemistry have secured a three-year Leverhulme Trust Research Project Grant totalling £140,000.
The award is to develop the design, assembly and functionalisation of peptide nanotubes, leading to nanothin metal wires.
This is based on a recent discovery in the Woolfson lab, in collaboration with Professor Paula Booth and Professor Leo Brady in the School of Biochemistry, of peptides that assemble into helical bundles with a central channel (see figure). These assemblies will form the molecular building block for the proposed nanotubes.
Professor Woolfson said: "The nice thing about the new protein structure that we have discovered, which we call CC-Hex, is that it is very appealing as a molecular building block for more complex and functional structures. For example, we are exploring possibilities of making enzymes and ion-channel proteins out of CC-Hex.
"The new grant takes us into the territory of assembling metal and semiconductor wires on the scale of approximately one thousandth the width of a human hair. At the moment this is basic science, but it will be interesting to see if we can construct tiny electronic circuits and devices with this bio-inspired approach."
The Leverhulme Trust was established in 1925 under the will of the first Viscount Leverhulme. It is one of the largest all-subject providers of research funding in the UK, distributing funds of some £60 million every year.
