Electrochemical imaging of fusion pore openings by electrochemical detector arrays

Electrochemical imaging of fusion pore openings by electrochemical detector arrays.

Opening of individual exocytotic fusion pores in chromaffin cells was imaged electrochemically with high time resolution. Electrochemical detector arrays that consist of four platinum microelectrodes were microfabricated on a glass coverslip. Exocytosis of single vesicles containing catecholamines from a cell positioned on top of the array is detected by the individual electrodes as a time-reso...

Electroanalysis of the Herbicide Diquat by Electrochemical Detector Containing Particles of Clay in Environmental Water

Clay modified carbon paste electrode (CPE-C) its applicability for electroanalysis of N, N’-ethylene-2,2’-bipyridinium (diquat) has been described in the present work. Electrochemical modification was performed by electronic impedance spectroscopy (EIS) and cyclic voltammetry (CV) in the range of -0.6 V to 1.2 V in 0.1 M K2SO4 (pH 3). The voltammetric method behavior of DQ is suggested where an...

Imaging Glucose Oxidase by Scanning Electrochemical Microscopy

Scanning Electrochemical Microscopy is a tool for imaging and investigate surfaces by meaning of chemical reactivity, electric conductivity, and enzymatic activity. This technique is typical electrochemical cell plus three axis positioner. Positioner allows to measure typical electrochemical measurements, like Cyclic Voltammetry, Chronoamperometry, Impedance Spectroscopy, etc. in the vicinity o...

Electrochemical fabrication of textured Bi2Te3 nanowire arrays

Initiated by the theoretical works of Hicks and Dresselhaus [1], the interest in nanostructured materials as more efficient thermoelectric materials has increased enormously. Recent experimental results on structures ranging from superlattices [2] to Si nanowires [3,4] emphasize the potential of tailoring materials properties by implementing finiteand quantum-size effects to circumvent classica...
