RE: Coloured or fluorescent liquids for microfluidics?

Dear Sung Jin,
You may want to try the following:
1 Fluoresceine - Which can be bought from most chemical supply
companies and is soluble in water and alcohol
2 Tartrazine - Same as fluoresceine
3 Go to your local foodstore and purchase some dye that would be used
for cooking and baking. We have used these dyes before and they are very
good. You can even get a selection of colours.
Hope this helps,
Coulton Legge
