Ratiometric Nanothermometer Based on a Radical Excimer for In Vivo Sensing (Small 32/2023)

Ratiometric Nanothermometers Organic nanoparticles based on persistent TTM radicals containing excimers and isolated molecules exhibit all characteristics of ratiometric nanothermometers showing excellent temperature sensitivity, reversibility, high colloidal stability. In-vivo experiments made with Caenorhabditis elegans (C. elegans) indicate that they can monitor changes at the (nano)-micron scale from 5 to 40 °C, very sensitivity indicating considerable potential applications in biological thermometry field.
