TL;DR: Experimental results demonstrated the successful functionalization of the films' surface with antibodies, with the immobilization occurring preferentially in the exposed nanoparticles and negligibly on the TiO2 matrix, which demonstrates the suitability for the development of cost-effective, label-free LSPR based immunosensor devices.

TL;DR: In this article, thin films composed of monometallic Au and Ag, and bimetallic Au Ag nanoparticles, dispersed in a CuO matrix were prepared, characterised and tested for Localized Surface Plasmon Resonance (LSPR) sensing.

TL;DR: In this paper, the development of nanoplasmonic thin films, composed of Au nanoparticles embedded in an Al2O3 matrix, was reported, and the thin films were tested using two dielectric (liquid) environments, showing a consistent response under different H2O/DMSO cycles, yet with low sensitivities (few nm/RIU).

TL;DR: In this article , gold nanoparticles (Au NPs) were dispersed into chitosan membranes by spin coating, and the results revealed that the lowest polymer concentration presented the most suitable plasmonic response.

TL;DR: In this paper , a review core presents and discusses the recent advancements in optical Ochratoxin-A biosensing, considering engineered nanomaterials, optical transduction principle and biorecognition methodologies.
