E34 - My little insects... (tattoos)
When I discovered that high-speed particles of ink were flying out of laser treated tattoos in 2012, I also found that many of these particles had been embedded in the glass slides.
Using an optical microscope I found that many of these ink particles looked like 'insects' - just like those in the movie Jurassic Park!
Below are a few of my photomicrographs for your pleasure.....
Note that the graduated marks visible in some of the above photos are 0.12mm apart, giving an indication of the size of these particles.
Below you can see the same field of view at different depths of focus. This means that these particles have penetrated to different depths within the glass slide...
You can clearly see different particles coming into focus at different depths.
