Immobilization of Streptavidin on a Plasmonic Au-TiO<sub>2</sub> Thin Film towards an LSPR Biosensing Platform

Immobilization of Streptavidin on a Plasmonic Au-TiO<sub>2</sub> Thin Film towards an LSPR Biosensing Platform

Optical biosensors based on localized surface plasmon resonance (LSPR) are the future of label-free detection methods. This work reports the development of plasmonic thin films, containing Au nanoparticles dispersed in a TiO<sub>2</sub> matrix, as platforms for LSPR biosensors. Post-depo...
