Latex beads 
Latex beads are spherical monodisperse particles made of poly(methyl methacrylate)
(PMMA), polystyrene (PS) or melamine formaldehyde (MF) as base material. Surface
modification and fluorescent labeling are performed during the preparation of the particles
preventing the leaching of the dye and changing of their surface chemistry. For
each size range the particles in pristine form (without surface modification), with surface
carboxylic group or fluorescent label or both can be synthesized. Beads of a specific
size range or fluorescence can be synthesized upon request, just let us know about your
requirements.
