The Role of Electrochemical Immunosensors in Clinical Analysis [PDF]

Biosensors, 2019
An immunosensor is a kind of affinity biosensor based on interactions between an antigen and specific antigen immobilized on a transducer surface. Immunosensors possess high selectivity and sensitivity due to the specific binding between antibody and corresponding antigen, making them a suitable platform for several applications especially in the ...

Multiplexed Electrochemical Immunosensors for Clinical Biomarkers [PDF]

Sensors, 2017
Management and prognosis of disease requires the accurate determination of specific biomarkers indicative of normal or disease-related biological processes or responses to therapy. Moreover since multiple determinations of biomarkers have demonstrated to provide more accurate information than individual determinations to assist the clinician in ...
