Heat capacity and heat generated per second of Au-nanoconjugates. Heat capacity of (a) AuNP@PEG 30% and (b) AuNP@PEG 100% for different exposure times and concentrations of AuNP in water irradiated at 2.37 W/cm². Four different concentrations of (c) AuNP@PEG 30% and (d) AuNP@PEG 100% were irradiated at 2.37 W/cm² for 60 s in water and the temperature variation was measured to calculate heat generated per second as a function of the number of particles irradiated. The slope of the curve gives the heat generated per nanoparticle per second
