摘要
菠菜组织微电极是一种新型的酶电极。应用该电极测定神经递质多巴胺(DA)时表现出较高的灵敏度和较好的选择性,它能够有效地消除抗坏血酸(AA)的干扰。其线性范围为1.7×10^(-6)～1.6×10^(-4)mol/L,检出下限为7.1×10^(-7)mol/L。对其在体测定DA的可行性研究,表明它是一种能够用于在体测神经递质的微电极。
The spinach tissue-based microelectrode is a new kind of enzyme electrodes. It shows high sensitivity and good selectivity when used in the detection of the neurotransmitter-dopamine. It can effectively eliminate the interference of ascorbic acid. The linear range is 1.7×10^(-6)～1.6×10^(-4)mol/L. The detection limit is 7.1×10^(-7)mol/L. The microelectrode can be used in the determination of neurotransmitter in vivo.
