IMDEA Nanociencia researchers measure the nanoscale heating of gold-based nanoparticles and find high temperature variations within a nanoscopic volume. Photothermal excitation of gold-based nanomaterials: the nanoparticle absorbs NIR (near infrared) light resulting in a localized heating. X-rays act as a probe of the local temperature.
