World's smallest shamrock created by scientists

Mar 17, 2014

AMBER, Ireland's national materials science centre based in Trinity College Dublin has etched a nano sized shamrock whose stem is approximately 200,000 times smaller than a grain of salt. The shamrock, 500 of which could fit side by side on a single human hair, has been etched on to a Trinity College silver lapel pin. The pin was presented to the recipient of the SFI St Patrick's Day Science Medal in Washington DC on March 13th at The Wild Geese Network of Irish Scientists by Professor Michael Morris, AMBER Principal Investigator.

The shamrock was etched using the AMBER Helium Ion Microscope in Trinity which is the only one in Ireland and one of only a handful in Europe. The microscope enables very of less than 1 nanometre and is used to image and pattern a range of materials. AMBER researchers use the microscope to image graphene and other 2D materials, bio-engineered scaffolds for tissue engineering and a range of polymer composites for research and industry purposes.
