Immobilization of amyloid β (Aβ)(1–40) peptide on Au-colloid modified gold electrodes has
been studied. Colloidal Au was self-assembled onto gold electrodes through the thiol …

Amyloid β (1-40) peptide was immobilized on an Au-colloid modified gold electrode and an
electrochemical impedance spectroscopy (EIS) system was elaborated for determining the …

Alzheimer's disease (AD) is connected to aggregation of amyloid-β (Aβ) peptide and
formation of insoluble plaques in the brain. Aβ level can be monitored as an AD early …

The electrochemical sensing of saccharide–protein interactions using a couple of sialic acid
derivatives and Alzheimer's amyloid-beta (Aβ) is described. The densely-packed saccharide …

Abstract β-Amyloid (Aβ) peptides are believed to be important for the diagnosis and
prognosis of Alzheimer's disease (AD) serving as reliable molecular biomarkers. In this …

We reported a general way to design electrochemical biosensors with peptide probes as the
receptors of targets and the inducers of gold nanoparticles (AuNPs) assembly on electrode …

In this study, we developed a small size, low cost, highly sensitive electrochemical biosensor
with a low limit of detection by immobilizing specific anti-amyloid-β (aβ) antibody onto a self …

Abstract A-beta (1-42) peptide (Aβ (1-42)) is a potential candidate for the prediction of
Alzheimer's disease. In this study, we demonstrate a nanostructured biosensor based on …

Alzheimer's disease (AD) is a widespread form of dementia that is estimated to affect 44.4
million people worldwide. AD pathology is closely related to the accumulation of amyloid …

In this work, a highly sensitive label-free immunosensor for detection of the main biomarker
of Alzheimer's disease (AD), amyloid beta 1–42 (Aβ (1–42)), is presented. A gold electrode …
