Surflay's monodisperse beads are not only fluorescent but also have tailored surface properties
Some possible surface modification options for PGMA particles
- Surflay labels their monodisperse particles with different (fluorescent) dyes during synthesis, thereby minimising leaching of dyes during applications.
- Embedding two or more dyes with defined ratios (multiplexing) in a particle matrix is also possible.
- Selected dyes absorb at wavelengths of commercially available lasers (405, 488, 532 or 635 nm) and exhibit both high fluorescence intensity and photostability.
- In addition, particle surface can be modified with specific reactive groups (carboxyl, glycidyl, iodoacetyl, azide or acetylene) or biomolecules via EDC, epoxy or click chemistry covalently bound to the surface.
