Polystyrene beads are available in several formats - unmodified, carboxyl-modified, or amine-modified - as well as various colors and numberous sizes. This particular product is an amine-modified bead containing a blue fluorescent dye. See the image below to review the basic structure. This is a surface modification that allows for the attachment of certain ligands such as polypeptides via the carboxyl-terminus. The dyes are embedded in the polystyrene bead during the manufacturing process. These are not bound to the surface of the bead.

Application
Amine-modified polystyrene latex beads (fluorescent orange) have been used to develop an electrochemical nitrite nanosensor as well as to validate a pharyngeal aspiration technique for exposing the mouse lung to respirable particles.
They have also been used:
- to test nanofiber filtration efficiency
- in the preparation of bilayer tissue-simulating phantoms, which are artificial materials used in biomedical optical instrumentation
- to copolymerize collagen coated stiff polyacrylamide gels to seed cancer cells for traction force microscopy
