Hydrogel structure under an electron microscope (IMAGE)
Caption
This image is a density-dependent coloured scanning of a piece of hydrogel using an electron microscope. Within the imaged hydrogel, regions higher in salt content are visualised as blue coloured regions, while less dense areas formed mainly by acrylamide are shown as red/purple.
