Uranium Removal with Protein Nanowires

Executive SummarySoil and groundwater contamination with uranium and radioactively contaminated waste pose serious environmental problems for human and animal consumption. Researchers at MSU have discovered that protein nanowire-expressing microorganisms are highly effective at precipitating and immobilizing heavy metal elements, including uranium,...

Electrobiocatalytic Reactor Including Reversible Bioelectronic Interface (split from TEC2005-0097)

IntroductionBioelectronics and biosensors are an integration of biological principles and electronic technology.  The key process in the tailoring of enzyme-electrodes, the vital connection between electronic and biological sciences, is efficient electrical contacting of redox-enzymes with electrodes.  Bioelectronic interfaces consisting of redox enzymes...

Reactor for Incompatible Gases

IntroductionMicroorganisms that produce biofuels may be used to produce a wide array of gasoline alternatives. Higher alcohols, like isobutanol, are good candidates for alternative fuels because their energy density and octane value are similar to gasoline. Isobutanol has a high octane rating, is oxygenated, non-hygroscopic, and non-corrosive. The autotrophic...

Customizable and Renewable Nanostructured Interface for Bioelectronic Applications

IntroductionBiomimetic interfaces consisting of synthetic lipid membranes allow proteins to be immobilized in an active conformation on a surface. The protein's activity is transduced into an electrical signal using electrochemical techniques to render a biosensor. Biomimetic interfaces that contain an upper layer of a hydrophobic lipid membrane, and...
