Application

Amine-modified polystyrene latex beads 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.
Latex beads, amine-modified polystyrene, fluorescent orange has been used in the preparation of nano-particles in biophysical characterization.[1] It has also been used in the preparation of nano-particles for cytotoxicity studies in yeast and cell lines.[2][3]
