Multitasking Nanotechnology

Tiny electronically active chemicals can be made to form ordered layers on a surface, thanks to research supported by the European Science Foundation (ESF) through the EUROCORES programme SONS 2 (Self-Organised NanoStructures).

These nanostructured layers may one day be used to build the components of electronics devices, such as transistors and switches, for a future generation of powerful computers based on molecules rather than silicon chips.

Speaking at the European Materials Research Society (EMRS) meeting in Strasbourg, SONS II scientist Marta Mas-Torrent explained the potential of nanotechnology: “Currently, there is a great interest in employing functional molecules as building blocks for preparing devices since this will facilitate the move towards device miniaturization.”

On this scale, manipulating nanoscopic components requires skill and determination but by exploiting molecular self assembly, the researchers hope to build ordered layers just a single molecule thick using microcontact printing techniques borrowed from the electronics industry.

They are now creating different arrangements of monolayers on gold, silica, and other materials.
