Cholinesterase-based Biosensor Using Surface Photovoltage Technique

Characterization of quantum well structures using surface photovoltage spectroscopy

In this work a novel method to characterize quantum well (QW) structures and devices is presented. The method is based on the well-known surface photovoltage spectroscopy (SPS) and on numerical simulations. It is shown that the surface photovoltage is sensitive to the electron hole energy transition levels in the well layer as well as to features of other regions of the structure. The photovolt...

Surface Plasmon Resonance: A Versatile Technique for Biosensor Applications

Surface plasmon resonance (SPR) is a label-free detection method which has emerged during the last two decades as a suitable and reliable platform in clinical analysis for biomolecular interactions. The technique makes it possible to measure interactions in real-time with high sensitivity and without the need of labels. This review article discusses a wide range of applications in optical-based...

Variation of Cholinesterase-Based Biosensor Sensitivity to Inhibition by Organophosphate Due To Ionizing Radiation

A cholinesterase based biosensor was constructed in order to assess the effects of ionizing radiation on exposed AChE. Although the primary objective of the experiment was to investigate the effect of ionizing radiation on the activity of the biosensor, no changes in cholinesterase activity were observed. Current provided by oxidation of thiocholine previously created from acetylthiocholine by ...
