    Abstract

    Abstract Image

    The use of plasmonic nanoparticles for biological applications has been gaining momentum in the last two decades. The ability of these particles to generate heat when exposed to light with a given wavelength is one of their prominent features. Quantifying the heat emission and relating it to the shape, size, and concentration of particles is of great importance. In this work, we show how lock-in thermography, a technique where temperature changes are obtained by means of an infrared camera, can be used to measure efficiently and non-invasively the heat generated by plasmonic nanoparticle solutions exposed to a modulated light source. We developed a mathematical model based on energy balance, where the heat generated by particles is computed from the absorption cross section of particles using Mie theory. The model, free of adjustable parameters, can quantitatively predict the heat generated by gold nanoparticles in suspensions in a broad range of concentrations and for two different wavelengths, which were experimentally investigated. The model and experimental data show how the amplitude of the temperature response increases linearly with the gold concentration, and is almost independent of the investigated particle size.
