Immunosensors are biosensors based on interactions between an antibody and antigen on
a transducer surface. Either antibody or antigen can be the species immobilized on the …

Methods based on sandwich-type immunosensors and immunoassays have been
developed for detection of multivalent antigens/analytes with more than one eptiope due to …

The early diagnosis of diseases, eg, Parkinson's and Alzheimer's disease, diabetes, and
various types of cancer, and monitoring the response of patients to the therapy plays a …

Immunoassays based on antigen–antibody specific recognition have attracted tremendous
attention as simple and rapid analytical methods. The detection sensitivity and efficiency are …

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 …

Electrochemical behavior of three antioxidants: butylated hydroxyanisole (BHA), butylated
hydroxytoluene (BHT) and butylated hydroquinone (TBHQ), was investigated at a glassy …

For the first time, the catalytic activity of nifedipine (NID) was studied at the surface of a
modified electrode which prepared by immobilization of Ag nanoparticles (AgNPs) at the …

Molecular biorecognition processes facilitate physical and biochemical interactions between
molecules in all crucial metabolic pathways. Perhaps the target analyte and the …

During the last decades the incidence of cancer increased dramatically especially in
developed countries. In spite of the fact that the immunochemical methods allowed the …

Graphene quantum dots-based immunosensors have recently gained importance for
detecting antigens and biomarkers responsible for cancer diagnosis. This paper reports a …
