An immunoassay method based on the peak shift of the localized surface plasmon resonance (LSPR) absorption maxima has been developed for the determination of the thyroid stimulating hormone (TSH) in human blood serum. The anti-TSH antibody was adsorbed on the synthesized gold nanoparticles by electrostatic forces. The efficiency of the nanobiosensor was improved by optimizing the factors affecting...
A localized surface plasmon resonance immunoassay has been developed to determine prolactin hormone in human serum samples. Gold nanoparticles were synthesized, and the probe was prepared by electrostatic adsorption of antibody on the surfaces of gold nanoparticles. The pH and the antibody-to-gold nanoparticle ratio, as the factors affecting the probe functions, were optimized. The constructed nanobiosensor...
