Hyperthermia treatment, particularly plasmonic photo-thermal therapy (PPTT), has become a promising means of cancer therapy. Biocompatible nanoparticles of controlled size and shape can be used to strongly absorb visible or near-infrared light and convert it to heat through surface plasmon resonance [1,2]. This causes a temperature rise in nearby tissues, which, based on the position and loading of the nanoparticles, can potentially kill cancerous cells while sparing healthy ones . Various types of gold nanoparticles (e.g., nanorods, nanoshells, and nanospheres) are generally used in PPTT because they have proven to be biocompatible [2-4] and are optically tunable through controlled size and morphology [2,5-8]. Monodisperse samples can be fabricated to possess strong visible (380–750 nm) and near-infrared (750–1400 nm) light absorption over a short wavelength band. Although several authors have proposed novel methods and models for PPTT [3,6,9,10], relatively few experimental studies have been reported to date. Deviations from these idealized models may affect experiments, due to nonuniform particle size through agglomeration, changes in optical properties, particle motion from thermophoresis, and other higher order effects. Additionally, much of the work to date has been based around expensive lasers as a heat source [1,2,11-13].
