生物传感器的开发研究可分为几个方面,其中之一是生物传感器的微型化。过去,是将电极等做为传感器的换能器(将化学信息转换成电信息)。目前,微型半导体(长5毫米,宽50微米)和利用半导体加工技术制成的微小电极已将其取而代之,研制出微型生物传感器。实际上是将酶固定在半导体的栅极、微小电极上,制做出微型酶传感器。上述传感器有可能用于人工脏器的监测或植入体内。若进一步微型化,将其封入微胶囊内,口服后或许可测定机体内部情况。 Development of biosensors can be divided into several areas, one of which is the miniaturization of biosensors. In the past, the electrode is used as a sensor transducer (chemical information into electrical information). Currently, micro-semiconductors (5 mm long and 50 μm wide) and tiny electrodes made using semiconductor processing technology have been replaced with miniature biosensors. In fact, the enzyme immobilized in the semiconductor gate, microelectrode, made of micro-enzyme sensor. The above sensors may be used for the monitoring of human organs or implanted in the body. If further miniaturization, it is encapsulated in microcapsules, after oral administration of the body may determine the situation.
