A new immobilization procedure for development of an electrochemical immunosensor for parathyroid hormone detection based on gold electrodes modified with 6-mercaptohexanol and silane
(Elsevier, 2015)
Fabrication of a new electrochemical impedance-based biosensor for the analysis of parathyroid hormone (PTH), using self-assembled monolayers (SAMs) of mercaptohexanol and (3-Aminopropyl) triethoxysilane on gold electrodes, ...
Ultrasensitive electrochemical detection of cancer associated biomarker HER3 based on anti-HER3 biosensor
(Elsevier, 2014)
The development of a new impedimetric biosensor for the detection of HER3, based on self-assembled monolayers (SAMs) of 4-aminothiophenol on gold electrodes, is reported. Anti-HER3 was used as a biorecognition element for ...
