“Photothermometer” : A PAOF system was constructed using a diode laser as the energy source, an aqueous suspension of plasmonic nanostructures as the photothermal transducer, and a glass capillary for measuring the volumetric expansion of the suspension (see picture). The suspension could be driven to move up the capillary by more than 30 mm and be used to control the operation of an electrical switch.
