An overview of the EIPAM network and collaboration with PEIC.

The ability to understand, manipulate and control physico-chemical processes at the molecular level is one of the great challenges of modern research and underpins the development of vibrant new technologies of the 21st century, for example the development of nanolithography. Such single molecule engineering requires selective bond cleavage in target molecules to allow subsequent management of the local site chemistry. Recent research has revealed that it is possible to influence the excitation and dissociation of molecules through the manipulation of electron interactions at the individual molecular level. Since electrons are ubiquitous in nature and electron induced reactions (in the gaseous phase, on surfaces and in the condensed phase) initiate and drive the basic physical-chemical processes in many areas of science and technology from industrial plasmas to living tissues our ability to control electron interactions provides exciting new opportunities that can now be exploited by both the research and technological communities. For example, the development of the Scanning Tunnel Microscope (STM) -an electron emitter- has introduced the capability of atomic-scale imaging, analysis and individual atomic/molecular manipulation providing a new technology that has the opportunity to revolutionize the scientific approach in many aspects of both the material and life sciences.

Many of these general aspects of the importance of understanding microscopic electron interactions can also be applied to the study of the electron's antiparticle, the positron. An understanding of the fundamental aspects of positron interactions with atoms, molecules and materials is becoming increasingly important in fields as diverse as nano-materials development and bioscience. For example, positrons are the key particle in the medical diagnostic, Positron Emission Tomography (PET), yet little quantitative information exists as to how they interact, at low energies, with biologically relevant molecules.
