Hot gold: The photothermal response upon pulsed laser irradiation is studied for pH‐responsive gold‐nanoparticle aggregates and compared to that of gold nanorods. The aggregates show a slight red shift in the absorption spectrum and retain the photothermal effect, whereas the nanorods lose the photothermal effect and exhibit a stark blue shift in the absorption.
