Development of conductometric glucose sensor in nanomolar (nM) range from phantom blood serum

Abstract Glucose detection has been an area of immense interest of scientists, researchers as well as clinicians worldwide for quite a long time. There have been many methods developed by the researchers to detect blood glucose but the detection methods were mostly limited to the order of ~0.1 mM. In this paper, we propose a very simple and cost-effective method to detect nanomolar (nM) levels of glucose in the human blood serum phantom sample. This method reports a significant improvement over the earlier known methods and can be used in extremely low-cost settings by scientists and researchers working towards the development of various chemical and biological sensors.
