Dandelions

Hybrid inorganic/polymer based photovoltaic nanodevices offer the promise of low cost large area conversion of solar energy to electricity. Nanostructures of zinc oxide have shown supreme capabilities in emerging technologies ranging from solar energy harvesting to biosensing. However, the ability to control the size and position of these nanostructures is crucial for fabricating nanodevices with remarkable properties and astonishing solar energy conversion efficiencies. Herein, we present a collection of scanning electron micrographs of zinc oxide nanostructures prepared by low temperature hydrothermal methods Image taken and Processed by Luisa Whittaker PhD.

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. Nicolson, "Kinocilia Mediate Mechanosensitivity in Developing Zebrafish Hair Cells", Developmental Cell, Vol 23, (2), pgs 329-341 (2012).

Ring of Plasmonics

The image shows a special plasmonic structure. On top of a gold layer a larger ellipse was created with electron beam lithography and ion beam etching. Subsequently, an additional gold layer was deposited. In the deeper ellipse structure eight smaller plasmonic ring structures were milled with the FEI Helios 650. The outer ellipse structure should enhance the signal of the smaller plasmonic ring structures.
