An emerging technology involving tiny particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. This heating must be carefully controlled however, since living tissue is delicate, and the ability to monitor temperature increases is crucial. In APL Photonics, scientists report a method to measure these temperatures using terahertz radiation. The study involved suspensions of gold nanorods in water in small cuvettes, which were illuminated by a laser focused on a small spot within the cuvette.
