Abstract

Abstract : The enticing features of extended gate sensor enables agile and inexpensive testing, yet reliable results in a short span of time. Our research has deciphered a novel sensing methodology for FET based sensors that enable detection of target ions in physiological conditions with a better selectivity, sensitivity and lower detection limit. The miniaturized sensor is packaged into disposable SD card chips which are portable and robust and have greater possibilities for development and integration as they do not require a reference electrode. The current technology can provide real-time monitoring of water quality which will be a great boon to humankind.
