Conjugated polyelectrolyte surface-grafted colloids

The presence of polymer brushes on the surface of silica particles can also be confirmed by electron microscopy and confocal fluorescence microscopy. As seen in Fig. 2.10a, transmission electron microscope (TEM) images of Si02 PPE particles show rough surface texture. It should be noted that no significant change in particle size was observed after grafting the polymer. The 

This chapter describes a broad range of optical biosensor technologies, based on interchromophore interactions and the super-quenching phenomenon. Several specific biosensor schemes are described that are able to sense the activity of kinase, protease, lipase, and cellulase enzymes. Although the systems are disparate, the underlying sensor mechanisms are related, in that they all
