我们开发了一种味道传感器，由多通道电极和传感器组成，该传感器由固定有聚合物的脂质膜组成，即与聚氯乙烯和增塑剂混合的八种不同的脂质类似物。这种多通道传感器以五种不同的方式响应五种基本味觉物质；对于五种基本味觉物质，由八种电势响应组成的味觉模式可以清楚地区分。此外，对于在人类中引起相似味道的物质，获得了相似但可区分的模式。与之前研究的味道传感器应用中的脂质膜相比，其再现性显着提高。目前的结果表明多通道脂质膜装置具有像人类一样感知味道的能力。
We have developed a taste sensor consisting of a multichannel electrode with transducers composed of lipid membranes immobilized with a polymer, i.e., eight different kinds of lipid analogs mixed with poly(vinyl chloride) and plasticizer. This multichannel sensor responds to five basic taste substances in five different ways; the taste patterns composed of eight electric-potential responses could be clearly distinguished from each other for the five basic taste substances. Moreover, similar but distinguishable patterns were obtained for substances eliciting a similar taste in humans. The reproducibility is noticeably improved from those of lipid membranes which were previously investigated for application in a taste sensor. The present results imply that the multichannel lipid membrane device has the ability to sense tastes like a human being.
