A unique, sensitive, highly specific, and photobleaching-resistant immunoassay system utilizing gold nanoparticles and surface-enhanced Raman scattering (SERS) is described. This new system, featuring a capability of bifunctional analysis, is manufactured by chemisorption of antibody immunoglobulin G (IgG) on gold nanoparticles (AuNP), followed by coupling(More)
A rigorous theoretical connection between the polarizability spectral density obtained from optical Kerr effect ~OKE! measurement with the correlation function describing solvent-induced optical dephasing detected in photon echo measurements is given. The experimentally obtained spectral density has a more reasonable physical basis than model correlation(More)
Previous nanoscale investigations of the gel-state membrane surface structure under the action of phospholipase A(2) (PLA(2)) suggest that single enzymes at work scoot on the membrane surface from the observed defects, which creates nanosized channels oriented along the lipid crystal-packing structure. To date, however, there have been no reports of direct(More)
