FIB-Patterned Silicon

There are two membranes with nanosized holes in silicon, produced by focused ion beam milling. The total width of each membrane is about 150 nm. The diameter of big holes is about 400 nm and small holes - 150 nm. Such structures can be applied in systems on chip.

Atomic Structure of a Family of Amyloid Fibrils

Pictured are the atomic-resolution structures of three amyloid polymorphs against a (falsely coloured) background image of the fibrils taken with a transmission electron microscope. Determining the fibril structures, and defining the major structural elements and interactions contributing to their hierarchical self-assembly, provides insight into the formation of polymorphic amyloid in a range of protein deposition disorders including Alzheimer’s and Parkinson’s diseases.

Zebrafish Neuromast

This is the cover page image published in Developmental Cell, August 14 2012. The Image was taken at Center for Electron Microscopy and Nanofabrication, Portland State University by instrument manager Greg Baty to support the post doctorial research work of Katie Kindt at OHSU (Teresa Nicolson lab Oregon Hearing Research Center). The research was funded by NIH and HHMI grant. The image is of a Zebra fish neuromast taken near the ear. Katie Kindt false colored the SEM image taken by Greg Baty Katie’s main interest in taking the SEM image was to examine the stereocilia and correlate the result with confocal studies that where performed while the zebra fish was alive. Katie and Gabe Finch at OHSU had a difficult time preparing the fish for SEM, due to the variability in a rapidly growing fish that is three days old. It was necessary to perform some digestion to expose the cilia for fixation. This was a very difficult imaging job for Greg since CEMN does not have a sputter coater with a tilting orbital stage and our Sirion is a high vacuum only instrument. The length and geometry of the cilia combined with charging due to poor coating tends to cause the celia to move in the electron beam. It took an interdisciplinary team effort to produce an image of this quality on a high vacuum XL30 Sirion. K. S. Kindt, G. Finch, and T.
