    Arachnoidiscus diatom

    6902

    An Arachnoidiscus diatom with a diameter of 190µm. Diatoms are microscopic algae that have cell walls made of silica, which is the strongest known biological material relative to its density. In Arachnoidiscus, the cell wall is a radially symmetric pillbox-like shell composed of overlapping halves that contain intricate and delicate patterns. Sometimes, Arachnoidiscus is called “a wheel of glass.”

    This image was taken with the orientation-independent differential interference contrast microscope.
    Public NoteA red Ferris wheel-like structure with a blue background.
    Internal NoteYes, I give my permission to add the three movies (crane fly, circular lamellipodia, and baby squids) and the mouse brain slice image to your image and video gallery. I would like to add new image of diatom Arachnoidiscus, which I called “Happy 4th of July”. Thank you, Michael Michael Shribak, Ph.D. Senior Scientist Marine Biological Laboratory/ University of Chicago 7 MBL St Woods Hole, MA 02543

    InvestigatorI would like to add new image of diatom Arachnoidiscus, which I called “Happy 4th of July”. The is image was taken with the orientation-independent differential interference contrast (OI-DIC) microscope (https://doi.org/10.1111/jmi.12682). Diatom Arachnoidiscus has silicified cell wall, which forms a radially symmetric pillbox-like shell (frustule) composed of overlapping halves that contain intricate and delicate patterns. Sometimes, it is called “a wheel of glass”. Diatom Arachnoidiscus deserves the term of “living photonic crystals” and can be employed for enabling sub-diffractive focusing of light. Diameter of shown diatom is 190µm.
