摘要: The invention discloses a silicon phthalocyanine functionalized TiO2 mesocrystal based aflatoxin photoelectrochemical detection method. method is characterized in that novel carbon nanocomposite formed by nanohorns and quantum dots serves as sensor support; dendritic quasi-octahedral introduced bioprobe to realize high-sensitivity of aflatoxin. CNHs CQDs has an excellent photoelectric property; SiPcs QOTM superior photocurrent response stability compared with single QOTM. An immunosensor enables mutual competition between standard AFB1 marked antibody specificity combination process, target object concentration intensity are linear relation range 10 -10 ng/ml. which universal provided for ultra-sensitive micromolecular substances.
