The Synthesis Of Chemosensors For Toxic Analytes, Johnathan Hugh Broome Aug 2016

The Synthesis Of Chemosensors For Toxic Analytes, Johnathan Hugh Broome

Dissertations

A number of chemosensors have been designed and synthesized to target cations (Zn2+ions), neutral molecules (cathinones), charged molecules (aminoindanes), and anions. The Zn2+ ion sensor featured bistriazole designed binding unit and ferrocene signaling units. Characterization of Zn2+ ion binding was carried out with electrochemical techniques (CV and DPV), 1H-NMR, mass spectrometry, and molecular modelling. It exhibited a 1:1 binding stoichiometry with Zn2+ and had an affinity for ZnCl2 (Log K1:1 = 4.1 ± 0.02) over other Zn2+ salts.

The cathinone probe was designed to selectively bind mephedrone over common ...


Developing A Biosensor For The Detection Of Bacteria: A Comparison Of Methods For Isolating Bacteria-Specific Antibodies, Scott Allen Walper May 2010

Developing A Biosensor For The Detection Of Bacteria: A Comparison Of Methods For Isolating Bacteria-Specific Antibodies, Scott Allen Walper

Dissertations

The antigen-antibody interaction is known to be a high affinity and highly specific interaction that can readily be used for the detection and identification of biological and chemical agents. These studies were conducted to develop an efficient and cost-effective method of obtaining bacteria-specific antibody molecules for integration into a fielddeployable biosensor. Antigen-binding molecules were obtained both as full-length IgG molecules from a hybridoma cell line and as recombinant single-chain Fv (scFv) antibodies isolated from naïve and immunize libraries. Monoclonal and recombinant antibody systems were compared on the effectiveness of producing new, target-specific molecules; the efficiency of production and purification of ...
