6. 4. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

   Author : Christopher Schulz; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

   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

7. 5. Advancements in Lithium-Based Batteries : Unraveling and Mitigating Performance-Limiting Phenomena in Negative Electrodes
