Synthesis of Novel Antimycobacterials and a Fluorescent Sensor for Simple Carbohydrates
… second objective was the synthesis of a simple fluorescent receptor for simple carbohydrates. A receptor using anthracene as the fluorophore has been completed demonstrating an improved yield over previous methods. This receptor is the first to show selectivity for myo-inositol over other …

Supramolecular assemblies of conjugated sensory polymers and the optimization of transport properties
(cont.) The vectorial energy transfer design of sensory films to harvest and direct energy to the surface detection layer toward ultimate signal amplification has been discussed. Third, the role of chemical structure of a sensory polymer in the selectivity of a conjugated polymer-based fluorescent …

In vitro selection and characterization of mono-, di-, and trivalent metal-dependent DNAzymes and their sensing applications
… Fe(III). We are in the process of designing a fluorescent sensor for Fe(II) based on the H5 DNAzyme. This sensor will be tested for intracellular imaging of Fe(II) in living cells. To obtain Fe(III)-dependent DNAzymes, different selection protocols and selection conditions were investigated. In …

Excited states and electron transfer in solution : models based on density functional theory
… to understand the photophysical behavior of a fluorescent sensor for aqueous zinc. Second, we discover that the delta-self-consistent-field ([Delta]SCF) approach to excited states in DFT offers accuracy comparable to that of the better-established but more indirect linear-response …
