Abstract
We report a single step procedure to prepare monodisperse
colloidal poly(methyl)methacrylate (PMMA) particles where fluorescent
dyes are incorporated into the polymer network. The
particles are sterically stabilized against flocculation by poly(12-
hydroxystearic acid). The fluorescent dyes are RITC (rhodamine
isothiocyanate)-aminostyrene (RAS) and 4-methylaminoethylmethacrylate-
7-nitrobenzo-2-oxa-1,3-diazol (NBD-MAEM), which
are prepared from (commercially available) RITC and 4-chloro-
7-nitrobenzo-2-oxa-1,3-diazol (NBD-Cl), respectively, as
