Detection of microRNA by electrocatalytically amplified nanoparticle collisions
(2017-06-16)
We report a new and general approach that will be useful for adapting the method of electrocatalytic amplification (ECA) to biosensing applications. In ECA, individual collisions of catalytic nanoparticles with a noncatalytic ...
Electrochemistry and electrogenerated chemiluminescence of unique organic chromophores and organic nanoparticles
(2011-05)
Electrogenerated chemiluminescence (ECL) studies were performed on several interesting compounds. A series of BODIPY derivatives was examined to understand the structural effects on the electrochemical, spectroscopic, and ...
Electrogenerated chemiluminescence of phenylquinoline-phenothiazine donor-acceptor molecules, dipyrromethene-BF₂ laser dyes and bent-pyrene-containing cyclophanes
(2003-12)
Four aspects of electrogenerated chemiluminescence were studied. First, the
effect of molecular geometry on the photophysical, electrochemical and ECL properties
of 3,7-[bis[4-phenyl-2-quinolyl]]-10-methylphenolthiazine ...
Detection of unstable intermediates and mechanistic studies in multisteps, two-electron transfer reactions by cyclic voltammetry and scanning electrochemical microscopy
(2014-05)
Unstable Sn(III) intermediates generated in the Sn(IV)/Sn(II) redox reaction in 2 M HBr + 4 M NaBr media were detected by scanning electrochemical microscopy (SECM) and cyclic voltammetry (CV). In CV, the underpotential ...
Studies in the photoelectrochemistry of bismuth vanadate using scanning electrochemical microscopy
(2012-12)
Photoelectrochemical studies were performed on bismuth vanadate (BiVO₄) to understand chemical and physical properties of the photocatalysts, and to improve the photoactivity for water oxidation. Scanning electrochemical ...
Electrochemically generated ion depletion zones for continuous separations in microelectrochemical devices
(2020-06-26)
The separation of chemical mixtures into pure and purer constituents is essential to humankind. However, the most common techniques for chemical separations are energy intensive and improvements in their efficiency are ...
The development of a metalloimmunoassay for the detection of NT-proBNP
(2021-05-07)
The purpose of this doctoral research is to develop a biosensor for the monitoring of heart failure (HF) in humans. Currently, there is no quantitative patient-facilitated method to monitor HF, and the physical symptoms ...
Microfluidics for bioanalytical research : transitioning into point-of-care diagnostics
(2014-12)
In this dissertation, three different microfluidic devices with bioanalytical applications are presented. From chapter to chapter, the bioanalytical focus will gradually become the development of a point-of-care sensor ...
The bioelectrochemistry of enzymes and their cofactors at carbon nanotube and nitrogen-doped carbon nanotube electrodes
(2014-05)
This dissertation explores the electrochemical behavior of enzymes and their cofactors at carbon nanotube (CNT) and nitrogen-doped carbon nanotube (N-CNT) electrodes. Two common types of oxidoreductases are considered: ...
Microelectrochemical devices and methods for investigation of complex surface modifications and electroactive thin-films
(2017-09-14)
Here we report on the development of microelectrochemical generation-collection flow devices and techniques for studies of complex electrode surface modifications and electroactive thin films. First we outline a new technique ...
