Resonance light scattering as a powerful tool for sensitive detection ofβ-amyloid peptide by gold nanoparticle probes†
Abstract
A novel biosensing strategy has been developed for sensitive detection of β-amyloid 1–42 (Aβ1–42) down to the ng mL−1 level in both aqueous solution and diluted human plasma, which is based on measuring changes in resonance light scattering of streptavidin functionalized
