An Electrochemical Sensor Based on Nickel Oxides Nanoparticle/ Graphene Composites for Electrochemical Detection of Epinephrine

The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...

Fabrication of an Electrochemical Immunosensor for Determination of Human Chorionic Gonadotropin Based on PtNPs/Cysteamine/AgNPs as an Efficient Interface

An ultrasensitive electrochemical immunosensor for the detection of tumor marker human chorionic gonadotropin (hCG) was developed with a limit of detection as low as 2 pg mL-1 in phosphate buffer. The Platinum nanoparticles (PtNPs) were electrodeposited to modify the gold surface and to increase enlarging the electrochemically active sites, resulting in the facilitation of electron exchange. Cy...

Development of an Electrochemical Immunosensor for Fumonisins Detection in Foods

An electrochemical affinity sensor for the determination of fumonisins mycotoxins (Fms) using monoclonal antibody modified screen-printed gold electrode with carbon counter and silver-silver chloride pseudo-reference electrode is reported in this work. A direct competitive enzyme-linked immunosorbent assay (ELISA) was initially developed, exhibiting a detection limit of 100 µg·L(-1 )for fumonis...

An electrochemical immunosensor based on antibody-nanowire conjugates.

Gold nanowires functionalized for electrochemical immunosensing were prepared and demonstrated to detect prostate specific antigen (PSA) with the sensitivity required in molecular and clinical diagnostics.
