Title:	NANOSCALE BIOCATALYSTS FOR BIOELECTROCHEMCIAL APPLICATIONS
Author:	Zhao, Xueyan
Description:	Rapid advances in nanoscale science and engineering are fueling the development of a new area in biotechnology, nanoscale enzymatic biocatalysis. Carbon nanotubes (CNT) are fascinating supports for enzyme immobilization because their specific surface area is extremely high; in addition, their high conductivity also makes them greatly useful for electrochemical applications. The overall objective of this study is to examine the use of CNT for construction of enzyme-based electrodes for electro-biochemical applications. Special focus is on the effect of CNT on reaction kinetics and mass and electron transfer processes on the enzyme electrodes. The kinetics of reactions were also examined and correlated to cell performance in order to understand governing factors of the cells. Glucose oxidase (GOx) was employed as a model enzyme for immobilization on CNT. The resulted composite electrodes were and investigated for applications including biosensors and biofuel cells with respect to apparent enzyme activity, stability, and overall electrode performance.
