1. Bioelectrochemical Applications of Reactions Catalyzed by Immobilized Enzymes
Abstract : The sensitivity of biosensors can be increased substantially by incorporation in a substrate recycling scheme. Based on the amplification of NAD+/NADH by the recycling reaction catalyzed by glycerol dehydrogenase (GDH) and diaphorase, NAD+/NADH can be determined amperometrically with around 1000 times higher sensitivity than for the substrate sensing mode.

2. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection
Abstract : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. READ MORE

3. Polyelectrolyte Brush Electrodes for Protein Capture and Release
Abstract : Stimuli-responsive polyelectrolyte brushes switch as a function of pH between a charged and neutral state that affects their electrostatic interactions with other charged molecules like proteins. Adjustment of the pH results in the binding of large quantities of proteins making polyelectrolyte brushes widely used as biointerfaces. READ MORE

4. Novel reagentless electrodes for biosensing
Abstract : Analytical chemical information is needed in all areas of human activity including health care, pharmacology, food control and environmental chemistry. Today one of the main challenges in analytical chemistry is the development of methods to perform accurate and sensitive rapid analysis and monitoring of analytes in ‘real’ samples. READ MORE

5. Amperometric biosensor-based microsystems for detecting analytes of biomedical importance
Abstract : Monitoring in the biomedical field is rapidly emerging as the most important application area of miniaturized analytical devices. Diagnostics, disease monitoring, drug development, and medical research are important areas taking full advantage of the short response time, reduced sample consumption, low costs, and reduced power requirements of miniaturized analytical tools.
