A shiny, perfectly straight ribbon of serial trapezoid sections floating in the water bath of a diamond knife. These are sections from a mouse brain embedded in plastic, each section is 70 nm thin!
A closeup of an ultramicrotome and the diamond knife used for cutting the ultrathin sections. There's a beautiful long ribbon of sections floating in the middle of the diamond knife boat and a coverslip is propped in, ready to pick the ribbon.
Celebrating the small (70 nm) victories today - look at these perfect serial sections that I cut!
