Studying delicate, organic samples typically requires analytical tools like X-ray crystallography, Cryo-EM, and NMR that only provide “snapshots” of real interactions. Using liquid cell EM, you can image biological samples in their native, hydrated environment at resolutions that allow you understand structural and chemical evolution in real-time.

Electron beam-induced growth of calcite nanoparticles in situ in the presence of AP7, a nacre protein that is found in abalone shellfish. The calcite particles were grown in the spatially confined conditions of the in-situ liquid cell in a liquid layer of 500 nm. During growth both a stable protein mediated scaffold-type structure, and an unstable crystalline structure which re-dissolved shortly after formation, were observed.

This movie shows a series of images that demonstrates the tilt range of Poseidon Select. Images of aggregated 30 nm gold nanoparticles in 1.5 μm of water were collected in 5° increments, over a total angle of -30° to +30°. Data was collected using a Philips/FEI CM300FEG TEM equipped with a GIF energy filter at 300 kV.
