An assay technology for high-throughput screening of kinase and phosphatase activities is introduced. The format is based upon superquenching of fluorescent-conjugated polymers by dye-labeled kinase/phosphatase peptide substrates. The sensor platform

Layer-by-layer thin films were prepared by the alternate deposition of clay particles and ionic organic compounds from solution onto a rigid support. The organic component comprised a monomeric cyanine dye or poly-l-lysine with the same cyanine chrom

An assay for a target single strand 20-base sequence of DNA coding for the anthrax lethal factor, based on conjugated polymer fluorescence superquenching, is reported. The assay employs a platform in which the receptor (a biotinylated complementary s

Both the photophysics and the fluorescence quenching behavior of an anionic conjugated polymer towards various small molecule quenchers can be modulated effectively by complexing the polymer with a simple countercharged detergent. For example upon ad

We present a study of the fundamental photoexcitations in a phenylenevinylene conjugated polymer from the visible to the mid-infrared (IR) using polarized subpicosecond transient absorption (TA) spectroscopy. From 0.5 to roughly 1.3 eV we find that f

To evaluate the role of nonphonon energy relaxation mechanisms in quantum dots and in particular the role of electron-hole (e-h) interactions, we have studied femtosecond carrier dynamics in CdSe colloidal nanoparticles in which the e-h separation (c

We report the synthesis and characterization of multi-layered organic superlattices made by polyelectrolyte self-assembly. Self-assembled films were formed from a water-soluble form of poly(phenylene vinylene) with high-photoluminescence quantum effi
