Abstract
The conventional methods for gas or liquid phase detection and analysis usually rely on the utilization of precision laboratory artificial instrument like chromatography-mass spectrometry (GC-MS). These methods provide an accurate approach for the analysis of type and concentration of the single component in a mixture of substances. However, these methods are time consuming, labor intensive, and expensive. The biomimetic smell and taste sensors provide novel solutions to overcome these drawbacks. In 1982, a novel gas sensing system, electronic nose (e-Nose), was proposed by imitating the sensing mechanisms of biological olfactory systems [1]. In 1990, the first liquid analytical instruments based on non-specific taste sensor array - electronic tongue (e-Tongue) was reported [2]. An e-Tongue using ion selective electrode array and pattern recognition algorithm was developed, which consists of a cross-sensitive chemical sensor array and pattern recognition algorithm and can be used to detect, analyze and identify the complex chemical compositions [3]. The Bioinspired smell and taste sensors (Bio-eNose and Bio-eTongue) mimic the biological chemical sensing mechanisms and could achieve a similar performance to biological olfactory and taste systems by the using of biological functional components for chemical sensing, which show prominent advantages such as high sensitivity, low detection limit, and excellent selectivity[4][5].
