Thermo-Plasmonics in Self-Organized Materials

Abstract

Thermoplasmonics deals with the generation and manipulation of nanoscale heating associated with noble metallic nanoparticles. To this end, gold and silver nanoparticles (AuNPs. AgNPs) are unique nanomaterials with the intrinsic capability to generate a nanoscale confined light-triggered thermal effect. This phenomenon is produced under the excitation of a suitable light of a wavelength that matches the localized surface plasmonic resonance frequency of AuNPs/ AgNPs.Liquid crystals (LCs) and hydrogels are temperature-sensitive materials that can detect the host AuNPs/ AgNPs and detect their photo-induced temperature variations. In this perspective, we present and discuss our latest efforts in the field of hydrogel/LCs based thermo-optical components. Moreover, in light of bio-related application, we present the first experimental evidence of the determination of D glucose concentration by exploiting AgNPs/hydrogel nanocomposites' properties.
