We demonstrate an analog type logical device that combines metalloprotein and organic/inorganic materials and can make an interactive analog decision. Myoglobin is used as a functional biomolecule to generate electrochemical signals, and its original redox signal is controlled with various mercapto-acids by the distance effect between myoglobin and a metal surface in the process of electron tra...

Microfabricated silicon/glass-based devices with functionalities of simultaneous polymerase chain reaction (PCR) target amplification and sequence-specific electrochemical (EC) detection have been successfully developed. The microchip-based device has a reaction chamber (volume of 8 microl) formed in a silicon substrate sealed by bonding to a glass substrate. Electrode materials such as gold an...

Electrochemical ion insertion involves coupled ion–electron transfer reactions, transport of guest species and redox the host. The hosts are typically anisotropic solids with 2D conduction planes but can also be materials 1D or isotropic pathways. These compounds have traditionally been studied in context energy storage find extensive applications electrocatalysis, optoelectronics computing. Re...

In this study, we report the light-emitting assistance effect of perylene on a polymer electrochemiluminescence (ECL) device using poly(3-octylthiophene-2,5-diyl) (P3OT). An ECL device is a liquid type self-luminous device with a simple structure, and can be fabricated by a relatively easy procedure. Significant improvement in luminescence properties was confirmed when 1.0 wt % perylene was add...

even though the use of enzymes as useful analytical reagents when immobilized onto a transducer such as an electrochemical device has been reported in the literature for nearly two decades, the direct, i.e. unmediated electrochemistry of enzymes is, nevertheless, a rather recent development. efforts will be made to introduce the fundamental basis for protein-surface interactions with emphasis o...
