Acta 巻: 354 ページ: paper No. 136673キーワード：概要：抄録：The present study describes the fabrication of 3D nucleated microparticles like Cu-MOF (MPsLCu-MOF)-
SWCNTs composite on glassy carbon electrode (GCE) by electrodeposition and applied as a sensor for the
sensitive determination of glucose in human saliva samples. First, SWCNTs were deposited on GCE by
potential cycling between 0.0 V to -1.0 V and then, Cu-MOF was electrodeposited on SWCNTs modified
GCE using a ligand, 1,3,5-benzene tricarboxylic acid (BTC), triethylamine hydrochloride and copper salt.
The SEM studies showed the formation of MPsLCu-MOF on SWCNTs as well as on bare GCE with 1 mm
size. The impedance studies showed that the heterogeneous electron transfer rate constant of
[Fe(CN)6]3-/4- was higher at SWCNTs-MPsLCu-MOF than bare GCE and SWCNTs and MPsLCu-MOF
modified GCEs. Then, the composite electrode was utilized for non-enzymatic detection of glucose.
The SWCNTs-MPsLCu-MOF modified electrode showed a well-defined sharp oxidation peak at 0.45 V
with enhanced current than bare GCE and SWCNTs and MPsLCu-MOF modified GCEs. As the concentration
of glucose increases from 10-160 10-6 M, the oxidation current also increases without shifting
its oxidation potential. The present composite modified electrode was also used to determine glucose in
the linear range of 20 10-9 M to 80 10-6 M by amperometry with a LOD of 1.72 10-9 M (S/N¼3) and
a superior sensitivity of 573 mAmM 1 cm 2. Finally, the composite fabricated electrode was exploited for
real-time analysis of glucose in human saliva samples and satisfactory results were obtained.英語フィールド
