Abstract(in Japanese) (See Japanese page)
Abstract(in English) Highly sensitive and selective detection of drugs(morphine and methamphetamine)was realized by using immunosensor based on surface-plasmon-resonance(SPR)phenomena. A drug-bovine serum albumin(drug-BSA)conjugate was prepared as an antigen. The conjugate was immobilized on the Au thin film of sensor chip by physical adsorption. The incident angle of the drug-BSA immobilized sensor increased with incresing concentration of anti-drug-BSA antibody. The addition of the drugs into the antibody solution was found to decrease the incident angle shift sharply because of the inhibition effect of the drugs. The present sensor was confirmed to detect morphine and methamphetamine very sensitively in the concentration range of 0.1-10ng/ml(ppb)and 0.1-1000ng/ml(ppb), respectively. From the correlation between incident angle shift and drug concentration, the affinity constants of each systems were evaluated by assuming Langmuir isotherm and equilibrium state of immunoreaction.
