Nanochannels Photoelectrochemical Biosensor
Analytical Chemistry, 2018Nanochannels have brought new opportunities for biosensor development. Herein, we present the novel concept of a nanochannels photoelectrochemical (PEC) biosensor based on the integration of a unique CuxO-nanopyramid-islands (NPIs) photocathode, an anodic aluminum oxide (AAO) membrane, and alkaline phosphatase (ALP) catalytic chemistry.

PHOTOELECTROCHEMICAL CELLS | Overview
2009The discovery that photoelectrochemical cells (PECs) can convert solar energy into useful fuels or electricity dates back to the early 1970s. Since then, considerable improvements have been made in cell design and in the choice of materials for photoelectrode, electrolyte, and auxiliary electrode.

Nature, 2001
Until now, photovoltaics--the conversion of sunlight to electrical power--has been dominated by solid-state junction devices, often made of silicon. But this dominance is now being challenged by the emergence of a new generation of photovoltaic cells, based, for example, on nanocrystalline materials and conducting polymer films.

Photoelectrochemical etching of semiconductors
IBM Journal of Research and Development, 1998Photoelectrochemical (PEC) etching of III-V semiconductors has been used to fabricate unique structures in electronic and photonic devices, such as integral lenses on light-emitting diodes, gratings on laser structures, and through-wafer via connections in field-effect transistors. The advantages and characteristics of PEC etching are reviewed, and the

Functional polymers in photoelectrochemical biosensing
Bioelectrochemistry, 2020Photoelectrochemical (PEC) analysis is a detection technique that has gained a wide attention in sensing applications. PEC presents the advantages of high sensitivity, low background signal, simple equipment and easy miniaturization. In PEC detection, light is used as an excitation source while current or voltage is measured as the output detection ...
