Experimenting with stains to see which gives the best view of the cell nucleus.
In order:
1. Unstained
2. Methylene Blue Stain
3. Janus Green Stain
4. Brilliant Cresyl Blue Stain
5. Bismarck Brown Stain
6. Neutral Red
All slides were wet mount slides viewed with the Foldscope (140X magnification plus the phone zoomed in to 5X magnification).
All stains were 1.0% alcohol solution (Methylene Blue was 1.0% aqueous solution) diluted to 0.1% with tap water.
