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 ...
Serological point-of-care and label-free capacitive diagnosis of dengue virus infection
(2020-03-01)
Dengue non-structural protein 1 (NS1 DENV) is considered a biomarker for dengue fever in an early stage. A sensitive and rapid assay for distinguishing positive from negative dengue infection samples is imperative for ...
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 ...
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 ...
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 ...
Perspective on quantum electrochemistry. A simple method for measuring the electron transfer rate constant
(2021-12-01)
