电活性物质 meaning in English

electroactive substance

The sensor could eliminate the interference of electroactive ascorbic acid , and exhibited high operational and storage stability ( no apparently difference in response of the biosensor was observed after been used continuously for 150 times and stored for 5 months )
传感器能有效消除电活性物质(抗坏血酸)对测量带来的干扰，同时具有较高的操作和贮存稳定性(连续使用150次、冷藏5个月后，响应无明显下降) 。
Although this method gives high sensitivity , the radioactive labels present many problems such as a potential hazard to analyst and environment , which limited its application in dna diagnostic laboratories . in order to overcome these problems a serious of non - radioactive dna probes such as fluorescent , chemiluminescent and electrochemical probes have been developed . although these new methods display many advantages , they have not been used to take place completely the traditional method because of low sensitivity or complex equipment or other shortcomings
自20世纪80年代以来，各种非同位素如酶、荧光素、生物素、地高辛标记的化学发光法和荧光分析法以及以电活性物质做标记的电化学方法相继问世，这些方法虽然在一定程度上克服了同位素标记的缺陷，但由于存在灵敏度不够高或检测系统庞杂或仪器价格昂贵或标记物不稳定等缺陷，还不能完全取代传统方法。
