11. Heterogeneous electron transfer studies with ligninolytic redox enzymes and living bacteria. Applications in biosensors and biofuel cells
Abstract : The catalytic properties and the inter-domain electron transfer of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on graphite and thiol (SAM) modified gold electrodes were investigated using cyclic voltammetry, flow injection amperometry and UV-Vis spectroelectrochemistry. The fabrication and characterisation of a noncompartmentalised, mediator and cofactor free glucose–oxygen biofuel cell well-operating in glucose-containing buffers and human blood serum was performed.

12. Biosensors for Food Analysis: Development and Applications
Abstract : Reliable analytical methods are increasingly needed in the food and beverage industry for the determination of specific components (e.g. sugars, proteins, vitamins, fats) and for detecting and quantifying chemical contaminants such as pesticides, heavy metals, antibiotics, and pathogenic microorganisms.

13. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges
Abstract : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. READ MORE

14. Development of Second and Third Generation Bioelectronics
Abstract : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.

15. 2nd and 3rd generation electrodes for biosensors and biofuel cells
Abstract : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. READ MORE
