In this present project we propose the study of new materials to improve the enzymatic biosensors by incorporating with in the device other chemical species that normally are in the solution-there by creating a "compact" biosensor-. Such a device is important for amperometric biosensors specially those which involve dehydrogenases as they also required a cofactor NADH and frequently a redox mediator. The development of an amperometric biosensor for detection of ammonium ions is being proposed with the intention of using them in a system for monitoring of heavy metal-by inhibiting the enzyme urease-. Additionally, we will study and develop "compact" biosensors-that do not need any added reagent-in order to measure enzyme activity of enzymes in the solution. These proposed biosensors will be constructed in a planar configuration with the intention of application to real samples of environmental or alimentary interest
