在当今信息时代,传感器是获取信息的主要工具,而生物传感器则是传感器家族中的后起之秀,是生物学与电子学相结合的产物,由生物感受器(酶、抗体或固定在膜上的微生物)和电子换能器组成,具有选择性好、灵敏度高、操作简便。应用面广等特点。当它与被检验的样品接触时,发生的生物化学反应由转换器转化为颜色、亮度、温度或电流的变化,然后经检测仪将信号放大后反映在数字显示器上。生物传感器的种类较多,已经实用化的主要有酶传感器,微生物传感器、免疫传感器、组织传感器及半导体生物传感器等。酶传感器是由不溶解的固体酶膜及氧电
In today’s information age, sensors are the main tool for obtaining information. Biosensors are the rising star of the sensor family. They are a combination of biology and electronics. They consist of bioreceptors (enzymes, antibodies, or microorganisms immobilized on the membrane) And electronic transducer composition, with good selectivity, high sensitivity, easy to operate. Wide range of applications. When it is in contact with the sample being examined, the biochemical reaction that takes place is converted by the converter into a change in color, brightness, temperature or current, which is then amplified by the detector and reflected on the digital display. More types of biosensors, has been the main practical enzyme sensors, microbial sensors, immune sensors, tissue sensors and semiconductor biosensors. Enzyme sensors are made of insoluble solid enzyme membranes and oxygen
