  2. 1. Nanoplasmonic Structures for Bio/Chemo Sensing

    Author : Tomas Rindzevicius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface-enhancement; biorecognition; nanostructures; surface plasmons; nanoholes.; biosensing;

    Abstract : Localized surface plasmon resonances (LSPR's) in noblemetal nanostructures are sensitive to refractive index changes close to the metal surface, and the LSPR's can therefore be utilized to sense molecular binding reactions. This thesis focuses on fundamental properties and proof-of-principle sensing studies of nanoplasmonic structures relevant for molecular detection. READ MORE
