Current Research
• Micro and Nano fabrication using: Proton Beam Writing (PBW), Nano Imprint Lithograph (NIL) and mold fabrication
• Micro & Nanofluidic lab on chip devices for single molecule detection and particle separation
• Materials modification using ion beams, e.g. Graphene, Magnetic materials and Diamond films.
• Ion source development for next generation ion nano-probes.

Brief Description of Research:
Microscopy has been an integral part of scientific development and has spurred development in many fields. Microscopy using fast protons has several advantages over other forms of microscopy. A fast incoming proton mainly interacts with substrate electrons, due to the mass mismatch between protons and electrons a proton beam practically follows a straight path through material. We can now focus proton beams down to 9.3 x 32 nm2, allowing high aspect ratio lithography down to 19 nm.
We are developing a user friendly ion microscope featuring 1-10 nm spot sizes. This new microscope will enable application like:

• Fast sub 10 nm 3D lithography without “proximity effects”.
• Sub 10 nm whole cell imaging, opening up new pathways to investigate the uptake of nanoparticles in drugs delivery.
• This new system will have accurate control over individual implanted ions, facilitating quantum device fabrication through deterministic ion implantation.
