摘要
提出了一种通过自行研制的聚苯胺/TiO2-PQC新型氨气传感器来实现迅速定量检测肺炎克雷伯菌的方法。该方法是利用肺炎克雷伯菌在有尿素的存在下能够产生大量的氨气和二氧化碳,此时产生的氨气能够与自制的聚苯胺/TiO2-PQC氨气传感器反应,并引起其表面电参数的变化,信号通过电脑输出,从而达到检测肺炎克雷伯菌的目的。经过研究结果显示,与SPQC相比新方法操作简单,更加灵敏以及不需要特定的培养基等特性,而且能够实现定量实时监测肺炎克雷伯菌。
A new ammonia sensor,which is modified polyaniline/TiO2,was proposed to detect Klebsiella pneumoniae,In this paper.This method is the use of Klebsiella pneumoniae in the presence of urea under can produce large amounts of ammonia and carbon dioxide, ammonia produced at this time capable of reacting with homemade polyaniline/TiO2-PQC ammonia sensor and cause the surface electric parameter changes,the signal output by the computer,so as to achieve the purpose of detection of Klebsiella pneumoniae.After the study showed that,compared with SPQC new method is simple,more sensitive and does not require a particular medium,such as features,and enables quantitative real-time monitoring of Klebsiella pneumoniae.
