文摘

Iron-Polymer-Graphene nanocomposites were constructed for competitive fluorescent immunoassay. The nanocomposites had low nonspecific adsorption to antigen. The nanocomposites could quench the fluorescence of QDs with high efficiency. Biomarkers of genetically modified crops could be sensitively detected.
