In this contribution an exceptionally simple, cost effective and reliable method for biosynthesis of ZnO nanoparticles through using Sageretia thea natural extracts as an effective chelating agent. The morphological analysis shows ZnO has nanoscale particles size 28.09 nm ± 5 nm, crystalline and possess distinct nanostructure hexagonal wurtzite structure. Effects of heat on ZnO synthesised at room temperature caused bonds with in the molecule to be broken exhibited continuous weight loss with 3 quasi sharp changes and 3 endothermic peaks occurring at 79°C, 228°C and 300°C. A proposed mechanism of reaction for Zn(NO 3 ) 2 6H 2 O precursor with bioactive compounds in Sageretia thea extract such as phenolic acid, flavonoids, natural sterolin and vitamin based compounds to form ZnO nanoparticles. Electrochemically ZnO nanoparticles are electroactive by exhibiting charge transfer resistance (R ct ) 82006 Ω and bare GCE 3.7707 × 10 5 Ω. Showed good catalytic and conductivity which can be applied for pseudo capacitors.

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.

“…Many central nervous system function and various diseases are related to its concentration in the nervous tissue and biological body fluid [30,31]. Therefore, the determination of trace LNE is very important in the pharmacological research [29] as well as the diagnosis of various diseases including mental disease, heart failure, DNA breaks in cardiac myoblast cells, and diabetes [32]. Moreover, LNE as a stimulant has been on the Word Anti-Doping Agency's 2005 Prohibited list.…”

“…l-Noradrenaline (1-(3,4-dihydroxyphenyl)-2-aminoethanol, LNE), a member of catecholamine type hormones, is an endogenous adrenoceptor agonist which acts on the parts of the brain involved with responsiveness and fear [29]. Many central nervous system function and various diseases are related to its concentration in the nervous tissue and biological body fluid [30,31].…”
