1. | Guglielmelli A.♦, Pierini F., Tabiryan N.♦, Umeton C.♦, Bunning T.J.♦, De Sio L.♦, Thermoplasmonics with gold nanoparticles: a new weapon in modern optics and biomedicine, Advanced Photonics Research, ISSN: 2699-9293, DOI: 10.1002/adpr.202000198, Vol.2, No.8, pp.2000198-1-17, 2021Abstract:Thermoplasmonics deals with the generation and manipulation of nanoscale heating associated with noble metallic nanoparticles. To this end, gold nanoparticles (AuNPs) 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. Liquid crystals (LCs) and hydrogels are temperature-sensitive materials that can detect the host AuNPs and their photo-induced temperature variations. In this perspective, new insight into thermoplasmonics, by describing a series of methodologies for monitoring, detecting, and exploiting the photothermal properties of AuNPs, is offered. From conventional infrared thermography to highly sophisticated temperature-sensitive materials such as LCs and hydrogels, a new scenario in thermoplasmonic-based, next generation, photonic components is presented and discussed. Moreover, a new road in thermoplasmonic-driven biomedical applications, by describing compelling and innovative health technologies such as on-demand drug-release and smart face masks with smart nano-assisted destruction of pathogens, is proposed. The latter represents a new weapon in the fight against COVID-19.Thermoplasmonics deals with the generation and manipulation of nanoscale heating associated with noble metallic nanoparticles.
