Sicastar beads (made out of silica) work in DBE:

I don't know of any silica beads with more than one fluorophore, and would be interested to hear if someone else has found any.
Best,

Can anyone recommend a source for beads made of a material other than polystyrene? I'm looking to make measurements in dibenzyl ether, which will dissolve styrene beads.
Thanks so much,
