• Sensitive competitive label-free electrochemical immunosensor for primal detection of ovarian cancer

    10 days ago - By Springer

    Abstract
    A simple, sensitive and one-step electrochemical technique was employed for the development of sandwich electrochemical immunosensor for the detection of CA 125 antigen. A unique three-dimensional gold nanostructure grown substrate is developed by electrodeposition technique to immobilize a large amount of anti-CA 125 through functionalization of gold nanostructures to immobilize cancer biomarker CA 125 and in human serum as well. The prepared immunosensor can directly amplify the electrochemical signal by making use of silicon nanoparticles conjugated with target antibody to...
