Abstract

Norepinephrine (NE) is an important catecholamine neurotransmitter that acts as a biochemical messenger in central nervous systems and neuronal cells of mammals, which is secreted and released by the adrenal medulla and the noradrenergic neurons during the synaptic transmission. It is often used for treating bronchial asthma, myocardial infarction hypertension and organic heart disease. Abnormal release of NE will contribute to the occurrence of many nerve related diseases, such as paraganglioma, ganglia neuroblastoma, ganglion neuronal, and Parkinson's disease. In addition, increased NE concentration in plasma is associated with coronary heart disease and with muscle sympathetic nerve traffic in human obesity. Furthermore, NE is involved in the occurrence and development of cardiac hypertrophy through the activation of myocardial adrenergic receptors on cell membranes in myocardial tissue. Therefore, the rapid, sensitive, and selective detection of NE level is significant for monitoring physiological function and diagnosing diseases. In this article the studies of detection methods for NE in recent years are reviewed.
