Molecular Electron Holography:
Progress toward atomic-resolution imaging?

October 20, 2009

Hans-Werner Fink’s group reports a remarkable advance in imaging individual biomolecules, with surprising physics, and (to me, at least) a somewhat mysterious date of publication.
The surprise is that it doesn’t destroy the molecules before imaging them.
The new generation of aberration-corrected electron microscopes achieve atomic resolution, but with a caveat — they succeed with robust, inorganic [...]

Graphene Nanotechnology
(and TEAM Microscopes)

April 2, 2009

I’ve intended to write about the wonders of graphene and related materials for nanotechnology, both as products and as a basis for building productive nanosystems, but there is so much to say that I didn’t know where to begin. As Rosa reminds me, though, a great virtue of a blog is that you can use [...]

3D Imaging & Research Opportunity [updated]

December 19, 2008

About the sample preparation techniques I described in an earlier post, Paul Rothemund writes to say
Those picture are neat; as far as I know, no one has done freeze fracture / freeze-etch electron microscopy [of DNA nanostructures]. That is a gap, certainly….
A study of the effects of critical point drying or freeze drying/sublimation on DNA [...]
