Electrochemical capacitive biosensors for point-of-care diagnostics: Principles and applications
(2016-01-01)
Before introducing the concepts involved in using capacitance measurements as an approach to transducer biological event into a measurable electrical signal, through electrochemistry interfaces, we will shortly make reference ...
The capacitive sensing of NS1 Flavivirus biomarker
(2017-01-15)
NS1 is a biomarker for different Flavivirus diseases such as dengue (DENV), zika (ZIKV) and chikungunya (CHIKV) and was herein selectively quantified by electrochemical capacitive sensing (an impedance-derived capacitance ...
Electrochemical capacitance spectroscopy and capacitive relaxation of the changeover process in iron hexacyanoferrate molecular compound
(Pergamon-Elsevier B.V. Ltd, 2010-08-30)
In this work it was proposed the use electrochemical capacitance spectroscopy (ECS) to evaluate the storage process during changeover in FeHCF compound. The approach is equivalent to electrochemical impedance spectroscopy ...

A dual marker label free electrochemical assay for Flavivirus dengue diagnosis
(2018-02-15)
Dengue is a RNA viral illness of the genus Flavivirus which can cause, depending on the pervasiveness of the infection, hemorrhagic dengue fever or dengue shock syndrome. Herein we present an electrochemical label free ...
Impedance-derived electrochemical capacitance spectroscopy for the evaluation of lectin-glycoprotein binding affinity
(Elsevier B.V., 2014-12-15)
Characterization of lectin-carbohydrate binding using label-free methods such as impedance-derived electrochemical capacitance spectroscopy (ECS) is desirable to evaluate specific interactions, for example, ArtinM lectin ...
Perspectives on and Precautions for the Uses of Electric Spectroscopic Methods in Label-free Biosensing Applications
(2019-01-01)
Label-free approaches for molecular diagnostic applications are appealing because of their inherent point-of-care advantages. Nonetheless, technical challenges impose a limit on the use of these methods as will be discussed ...
