Preparation of Monodisperse, Fluorescent PMMA–Latex Colloids by Dispersion Polymerization

“…We have shown that PMMA-latex particles can be fluorescently labeled by adjusting the single-step dispersion polymerization as described by Antl et al (10). Small fractions of fluorescent monomers can participate in the polymerization reaction and homogeneous fluorescent particles are obtained.…”

“…Fewer "nuclei" precipitate and the spheres grow larger. Similarly, it has been found that at higher levels of the polar monomer, larger particles are formed (10). The reason for adding acetone is to dissolve the fluorescent monomer.…”

“…When the monomers react, polymers are formed that are insoluble in the dispersion medium. After a period of time, the polymers precipitate and latex particles are formed (10,14,15). Only apolar media are considered here.…”

“…The preparation of homogeneous fluorescent latex particles as described in this section was done analogous to the methods described in (10,19,20). For the synthesis a standard reflux setup was built.…”

“…A simple method for preparing colloidal particles that is widely used in colloid chemistry is a procedure reported by Antl and coworkers (10). In the work presented here, this procedure is modified to incorporate fluorescent monomers into the polymer chains that make up the particles.…”
