串联式压电石英晶体猪肾组织谷氨酰胺传感器的研制

Preparation of Glutamine Sensor with a Series Piezoelectric Quartz Crystal Device and Slices of the Pork Kidney Tissue

用串联式压电石英晶体作为敏感元件，将猪肾组织切片固定在其透气膜表面，研制了一种动物组织谷氨酰胺传感器。在５．０×１０－６～３．０×１０－３ｍｏｌ·Ｌ－１浓度范围内，传感器响应时间为４～５ｍｉｎ，使用寿命在３周以上，不需要任何电极，灵敏度高，结构简单。

The purpose of this study was to prepare glutamine sensor with a series piezoelectric quartz crystal(SPC) device and slices of pork kidney tissue.The best response condition was determined and response activity was evaluated.The results showed that when glutamine was during 5.0×106～3.0×103 mol·L1),the response time is from 4 to 5 minutes.It is concluded that the tissue sensor has high sensitivity and simple structure.
