In Situ visualization of the local photothermal effect produced on α-CycloNataly Silvadextrin inclusion compound associated with gold nanoparticles

Evidence of guest migration in α-cyclodextrin-octylamine (α-CD-OA) inclusion compound (IC) generated via plasmonic heating of gold nanoparticles (AuNPs) has been studied. In this report, we demonstrate local effects generated by laser-mediated irradiation of a sample of AuNPs covered with inclusion...
