AB  - The last few years have seen a growing interest in the ability of metallic 
      nanoparticles (MNPs) to control temperature at the nanoscale. Under a suitable 
      optical radiation, MNPs feature an enhanced light absorption/scattering, thus 
      turning into an ideal nano-source of heat, remotely controllable by means of 
      light. In this framework, we report our recent efforts on modeling and 
      characterizing the photo-thermal effects observed in gold nanoparticles (GNPs) 
      dispersed in thermotropic Liquid Crystals (LCs). Photo-induced temperature 
      variations in GNPs dispersed in Nematic LCs (NLCs) have been studied by 
      implementing an ad hoc theoretical model based on the thermal heating equation 
      applied to an anisotropic medium. Theoretical predictions have been verified by 
      performing photo-heating experiments on a sample containing a small percentage of 
      GNPs dispersed in NLCs. Both theory and experiments represent an important 
      achievement in understanding the physics of heat transfer at the nanoscale, with 
      applications ranging from photonics to nanomedicine.
