Welcome to the UC Research Group Website !
 
This website is regularly updated with some of the research undertaken by the Surface Chemistry, Electrochemistry & Analytical Group in the Department of Chemistry at University of Canterbury
 
Our Main Research Areas include:
 
(1) Fabrication & Surface Modification of Substrates (Carbon, Gold, Silicon) via the attachment of tether molecules & the study of their nano-scale film structures
 
(2) Electrochemistry of Chemically Modified Electrodes (attachment of enzymes) for Bio-Fuel Cell applications
 
(3) Fabrication of and Electrochemistry at Vertically Aligned Carbon Nanotube Electrodes
 
 
The studies from these programmes help in the development of portable devices in freshwater analysis, microelectrodes, chemically modified electrodes & biochips for bio-fuel cell & sensors, nanoparticle assemblies for smart materials, novel electrode material for catalysis of industrial processes.
 
Our research programmes include collaborations with The MacDiarmid Institute for Advanced Materials & Nanotechnology, & Canesis Networks Ltd.
