During Michaelmas Term, OxTalks will be moving to a new platform (full details are available on the Staff Gateway).
For now, continue using the current page and event submission process (freeze period dates to be advised).
If you have any questions, please contact halo@digital.ox.ac.uk
We develop new methods for sample application and vitrification and implement them into a novel platform. The apparatus can be fed with pre-mounted autogrids, circumventing the need for postmounting. For single particle analysis (SPA), minute amount of samples can be applied directly onto a supported film. For cellular work, sample carriers with cells grown on them will be exposed to an airknife that removes excess medium. Sample evaporation will be minimized by a feedback loop that maintains the sample near its dewpoint calculated from the ambient temperature and humidity. Vitrification will be accomplished by jet-streaming liquid ethane onto the centre of the grid. I will be happy to share our latest results.
