Webcast: How Image Accuracy Impacts Your Research

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.

Self assembly of 500 nm polystyrene nanospheres onto optical photoresist. The nanospheres acts like microlenses, exposing the resist and patterning it with a dot structure. After metalisation (in this case sputtered permalloy) the following lift-off leaves the metal structure on the upper pert of the microphoto. In the lower part the original array of self-assembled nanospheres used as microlenses.

The in vivo interaction between a wild type P. aeruginosa biofilm, on a silicone implant, and the responding polymorphonuclear leukocytes. SEM visualization depicts the interaction at day 1 post insertion of the implant in peritoneal cavity of a mouse. The leukocytes (yellow) are killed by the bacteria (cyan), as seen from their damaged appearance, with obvious cavities in the membrane, after contact with the WT biofilm.

This cyanobacterium (Nodularia sp.) shows symbiotic bacteria (bacilli) intimately associated to the mucilage cover (extracellular polymeric substances) that serves as their food substrate. This cyanobacterium cannot be isolated without its symbiont.

It is Er doped ZnO compound. It was produced by sol-gel method. ZnO is a wide-bandgap semiconductor. As can be seen from the figure, it has hexagonal structure. ZnO has several favorable properties, including good transparency, high electron mobility, wide bandgap strong room-temperature luminescence that used in various applications. And the properties that mentioned above can be improved by adding some kind of dopings Because of these reasons we have tried to produced Er doped ZnO in nanoscale.
