Welcome to the nanomechanics laboratory at Trinity College Dublin. As the leader of this group I welcome you to visit our website, correspond with members of our group and discuss your technical interests with us. Our laboratory is focuses on the dynamics and kinetics of interacting biomolecules, the mechanics of protein imported to mitochondria membranes, the kinetics of molecular motors under external strain and the nanomechanical action at ribosomal complexes during translation. We utilize state of the art combined force- and light spectroscopy tweezers instruments for single molecule analysis and are also leaders in the development of cantilever array devices and taylor made bio-engineered nano-mechanical biosensors quantitative diagnostic assays in genomics (miRNA diagnostic and siRNA pharmakokinetics), proteomics, and microbio (environmental and ) sensing applications. Most of our developed devices and assays are used in translational science in collaboration with hospitals (St. James Hospital, Dublin) and health institutes (Swiss Tropical Institute, Basel).
A team of 4 researchers (Physics, Molecular Biology, Bioengineering, Nanoscale Science) under the guidance of Martin Hegner is currently developing the next generation of nano-mechanical assays. With several national and international collaborations we are involved in a multi-disciplinary team effort with the goal of developing specialized devices and assays for a rich variety of applications. We are committed to changing the world through discoveries and development of new technologies. Our efforts begin where the imaginative mind meets the experienced. We are excited about what future technology can offer society.
