A model is showing the charge transfer (e --RRB- mechanism of Rhodamine B molecules (top) interacting with N - doped graphene (bottom sheet) when excited with different laser lines, which leads to ultrasensitive molecular sensor with N doped graphene. (sciencedaily.com)
If nuclear counterstaining is desired, four - color antibody staining is possible using BV421, BV480, Alexa Fluor 488, and Rhodamine Red - X. (sciencemag.org)
Cells were then fixed with two percent paraformaldehyde and stained with rhodamine phalloidin to allow visualization of filamentous actin. (sbpdiscovery.org)
