Abstract

Silica-coated gold nanorods provide a multi-fold improvement in the sensitivity of photoacoustics-based temperature mapping compared to gold nanorods without silica coating. The results indicate that photothermal therapy can benefit from nanoparticles designed to enhance photoacoustic response and to act as sensitive photoacoustic thermal sensors for accurate temperature mapping during image-guided photothermal therapy.
