New approach of optically encoded PS beads has been prepared by miniemulsion. This kind of beads consists of a determined fluorescent polystyrene (PS) nanocomposite core and a poly(acrylic acid) brush shell. Figure 1. <img src='https://acs-archive-assets2.s3.amazonaws.com/242nm/uploads/82494_ruby_fridge.jpg' alt='' /> Quantum dots (QDs) are well confined in PS core to decrease toxicity of Fluorophores. The shell of spherical polyelectrolyte brush is capable of immobilizing metal nanoparticles and proteins. Therefore, these fluorescent spherical polyelectrolyte brushes have potential applications in traceable catalysis and drug delivery.
