Fluorescently Doped Polystyrene (PS) Microspheres

Anyone know of a good protocol for doping premade polystyrene
microspheres with a hydrophobic fluorophore. Any suggestions would be
of much help and would also be appreciated greatly.

there is a botech called luminex; I believe they put the spheres and dye in toluene, the spheres expand and absorb the dye by passive diffusion, and they quench by dilution into water

Ensure that the roach is handled with a good pair of Zircon encrusted tweezer to prevent unwanted burns to your appendages.
