 Advances in electrochemistry and sensor (bio sensor s and chemical sensors) research and development have come about due to the need to meet the indigenous demands of the food industry, for environmental analysis, and for biomedical applications. Research is carried out in three areas, for which there is a need to develop existing approaches for better performance of the sensor s, improve analytical methods and explore possible new applications. The bio sensor s and chemical sensor s technology group can be sub-divided into the following lines of study:
- Bio sensors: Microbial BOD sensors, phenol enzyme bio sensors, screen-printed glucose oxidase electrodes, and simultaneous determination of glucose and sucrose.
- Chemically modified electrodes: Biocompatible redox polymer membrane, metal microparticles in polymer films, inorganic film modified electrodes, and nafion-coated probe in viscous/resistive media.
- Electroanalytical techniques: Pulse amperometric detection, artificial neuron networks for interpreting voltammetric data, and stripping analysis.
The following are some current research projects in this group.
- Microbial BOD sensors
- Screen-printed electrodes for blood-glucose determination
- Screen-printed electrode for pesticide detection
- DNA-modified screen-printed electrode for Escherichia coli detection
- Development of solid polymer electrolyte of redox gases using interdigitated array microelectrodes
