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:

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
