  1. 1. Affinity biosensors based on a capacitive transducer

    Författare :Christine Berggren; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. LÄS MER
