Little is known currently about the fate of nanomaterials post photothermal ablation and the implications thereof. In addition to having deep penetration depths in tissue, NIR light is innocuous to normal cells. Both statistical and single-specimen results demonstrated the excellent thermophysical resolution of the technique with prospects for its use in the nonintrusive, on-line identification of counterfeit banknotes.įractionated photothermal antitumor therapy with multidye nanoparticlesĭirectory of Open Access Journals (Sweden)įull Text Available Luke G Gutwein1, Amit K Singh2, Megan A Hahn2, Michael C Rule3, Jacquelyn A Knapik4, Brij M Moudgil2, Scott C Brown2, Stephen R Grobmyer11Division of Surgical Oncology, Department of Surgery, College of Medicine, 2Particle Engineering Research Center, 3Cell and Tissue Analysis Core, McKnight Brain Institute, 4Department of Pathology, University of Florida, Gainesville, FL, USAPurpose: Photothermal therapy is an emerging cancer treatment paradigm which involves highly localized heating and killing of tumor cells, due to the presence of nanomaterials that can strongly absorb near-infrared (NIR light.
The radiometric photothermal amplitudes and phases were further compared with a theoretical model, which yielded simultaneous quantitative measurements of the thermal diffusivities and conductivities of the bills. ($DOL50, $DOL100) currency bills were printed. Laser-induced, frequency-scanned IR photothermal radiometry was used to investigate the thermophysical properties of the paper on which several genuine and counterfeit British (10 pounds) and U.S. Othonos, Andreas Mandelis, Andreas Nestoros, Marios Christofides, Constantinos Laser photothermal diagnostics of genuine and counterfeit British and United States banknotes Representative agents that have been studied in the context of photothermal therapy since 2000 are summarized and recent advances in using PTT agents to address various cancers indications are highlighted. In this tutorial review, we provide a structured description of the main classes of organic photothermal agents and their characteristics. Over the last decade, organic photothermal therapy (PTT) agents have attracted increasing attention as a potential complement for, or alternative to, classical drugs and sensitizers involving inorganic nanomaterials.
