Label-free detection of DNA using novel organic-based electrolyte-insulator-semiconductor.
In this study, we have constructed the first organic field effect sensor based on an electrolyte-insulator-semiconductor structure (OEIS) and applied this novel device to pH and DNA sensing. Variations in the insulator-electrolyte surface potential, which originate from either the change of the ionization states of the insulator surface groups or the binding of charged molecules to the insulato...
متن کاملIntegration of a Capacitive EIS Sensor into a FIA System for pH and Penicillin Determination
A field-effect based capacitive EIS (electrolyte-insulator-semiconductor) sensor with a p-Si-SiO2-Ta2O5 structure has been successfully integrated into a commercial FIA (flow-injection analysis) system and system performances have been proven and optimised for pH and penicillin detection. A flow-through cell was designed taking into account the requirement of a variable internal volume (from 12...
متن کاملSilicon Carbide-Based Hydrogen Gas Sensors for High-Temperature Applications
We investigated SiC-based hydrogen gas sensors with metal-insulator-semiconductor (MIS) structure for high temperature process monitoring and leak detection applications in fields such as the automotive, chemical and petroleum industries. In this work, a thin tantalum oxide (Ta2O5) layer was exploited with the purpose of sensitivity improvement, because tantalum oxide has good stability at high...

متن کاملVisualization of Ion Distribution by the Chemical Imaging Sensor
For the visualization of chemical species in the solution, markers and labels such as fluorescent dyes are often utilized. For certain applications in biology, however, toxicity of such dyes may be a problem, especially in the case of cells and tissues in culture. In this study, a label-free method of ion imaging based on a semiconductor device is developed. Chemical sensors based on semiconduc...
