Trapped Ion Imaging for Biomolecular Dynamics. The functionality of large biological molecules is driven by their chemical composition and the folded shape of their active form. The higher-order structure and dynamics of nucleic acids, proteins, carbohydrates, and lipids drives the chemistry of life. Combining single molecule microscopy and trapped ion mass spectroscopy will develop a new tool for precision measurements of higher-order folding dynamics in large biomolecules.

The functionality of large biological molecules is driven by their chemical composition and the folded shape of their active form. The higher-order structure and dynamics of nucleic acids, proteins, carbohydrates, and lipids drives the chemistry of life. Combining single molecule microscopy and trapped ion mass spectroscopy will develop a new tool for precision measurements of higher-order folding dynamics in large biomolecules. Optical techniques including Förster resonance energy transfer and super-resolution imaging can register changes in shape down to the nanometer scale. The uniquely adaptable ion trap environment enables manipulation of the surrounding solvent cage, temperature, and net charge down to the single quantum level. Read moreRead less
Positron Nano-Dosimetry: Fundamental Measurements of Positron Interactions and their use in State-of-the-Art Modelling of Positron Transport. This proposal will provide unique experimental and theoretical information on how positrons, the electron antiparticles, interact with matter, in particular with biologically important molecules. This data will be used in a unique set of modelling approaches which will provide, for the first time, an insight into how positrons are transported through gases ....Positron Nano-Dosimetry: Fundamental Measurements of Positron Interactions and their use in State-of-the-Art Modelling of Positron Transport. This proposal will provide unique experimental and theoretical information on how positrons, the electron antiparticles, interact with matter, in particular with biologically important molecules. This data will be used in a unique set of modelling approaches which will provide, for the first time, an insight into how positrons are transported through gases, liquids and ultimately, soft matter. It will thus have important ramifications for diagnostic tools such as Positron Emission Tomography. The fundamental research will also shed light on one of the key 'mysteries' of life - why the biological building blocks of life possess a definite " handedness", or chirality.Read moreRead less
