Multitasking nanotechnology
Date:7/10/2008

ised with PTM radicals will allow them to fabricate multifunctional surfaces which can be interconverted between two states that exhibit different optical and magnetic properties that can be used as read-out mechanisms.

"The ultimate goal is to employ these radical building blocks to construct nanometre-scale devices addressed to specific applications," explains Mas-Torrent. By immobilizing them on specially prepared surfaces they could control and observe electrical and magnetic behaviour and in the future perhaps hook them up to input and output devices.

Key to the team's success is the collaborative possibilities opened up by the program. "Veciana's group started working on the functionalisation of surfaces after the collaboration initiated with the group of Reinhoudt from the MESA+ Research Institute in Twente within the SONS Programme," explains Mas-Torrent. "The combination of the expertise of surface functionalisation from Twente with the expertise of functional molecules of Barcelona emerged in our recent results focused on the functionalisation of different surfaces with multifunctional molecules (paramagnetic, electroactive and fluorescent) which can act as molecular switches," Mas-Torrent adds.

Mas-Torrent concedes that "much more fundamental research works need to be carried out" before applications become available. "We hope that in the future, molecular devices will play an important technological role in our society," she adds.
