  • Electrochemical immunosensor and method of use for analyte detection
    Patent number: 10605806
    Abstract: A carbon nanofiber-based label free electrochemical immunosensor for sensitive detection of proteins in a fluid is described. The immunosensor as disclosed is a modified carbon nano-fiber screen printed electrode (CNF-SPE) wherein the electrode is modified with a carboxyphenyl film and then activated by EDC/NHS. Further, a monolayer of 4-aminophenylboronic acid coating was then fabricated onto the electrode to allow orientation of antibody via bonding of boronic acid-saccharide of oligosaccharide moiety located on the Fc region of antibody. The modified electrode is then used for the detection of a hormone such as rbST in a fluid with a detection limit of 1 pg/ml.
