Verfahren zur Charakterisierung von technischen Oberflaechen

EP 1574859 A UPAB: 20051024 NOVELTY - In a process to characterise a surface nano-domain, biosensors incorporating immobilised affinity molecules on nanoparticles are incubated on a surface incorporating nano-domains. The bond between biosensors and surface nano-domain is characterised by a detection assembly. DETAILED DESCRIPTION - In a process to characterise a surface nano-domain, biosensors incorporating immobilised affinity molecules on nanoparticles are incubated on a surface incorporating nano-domains. The bond between biosensors and surface nano-domain is characterised by a detection assembly. The affinity molecule is e.g. an oligonucleotide, polynucleotide, natural or synthetic antibody or fragment thereof, an aptamer, a lectin, a peptide, an oligopeptide, an amino acid derivative, a nucleotide, glycoprotein, a cofactor, a vitamin, an enzyme, a bacteria and/or a virus. USE - The process is used to characterise a surface nano-domain in a medical application e.g. dialysis membrane. ADVANTAGE - The method shows the relationship of the flat surface to a polymer-nanodomain, biosensor and gold nanoparticle
