B. subtilis peeking through a filter

A false-color scanning electron micrograph I took the other day of a B. subtilis bacterium peeking through a polycarbonate filter.

 

Magnification: 40,000X (the bacterium is about 0.5 micrometers in diameter; compare that with the average width of a human hair, which is 70 micrometers--this bacterium is 140 times smaller!). To the naked eye, this filter just looks like a perfectly smooth surface, and you'd never come even close to seeing that there were bacteria on it!

 

Since electron microscopy uses electrons instead of light to look at a specimen, there is no color in an image straight from the machine. Thus, color is often applied after the fact to make the image more interesting to look at.

    icthologist, what's special about Anopore filters? This was taken on an Isopore filter. Are they similar?

    How about doing a flower macro using an electron microscop and stitching 10s of thousands of pictures together. Imagine the resolution. You could print the flower as big as a house and there is still no pixelation.

    Great shot.

    skypecaptain, what a crazy idea! That would indeed be an amazing sight to see. I think you could probably actually print it bigger than a house. More like a football field!

    Beautiful shot. So, can you get the SEM in a Nikon fit? ;o) And I thought macro was a different world!

    Exciting!!!
    I love that you took the time to explain what was on your picture too. Thank you.

    It's cool that you titled these "inner space" because when i was young, i had this windows 3.1 program called "inner space" and you looked at sweet microscopic stuff. also this pic is awesome.

    makes me think of cheese. love it. so cool.

    Hey, great image. I have just added my artwork which is inspired by images of atoms as seen through modern microscopes. So came across your images, very inspiring, thanks
