Título: | Gold nanostars as thermoplasmonic nanoparticles for optical heating |
Autor: | Rodríguez-Oliveros, Rogelio CSIC; Sánchez-Gil, José A. CSIC ORCID | Fecha de publicación: | 23-dic-2011 | Editor: | Optical Society of America | Citación: | Optics Express 20: 621-626 (2012) | Resumen: | Gold nanostars are theoretically studied as efficient thermal heaters at their corresponding localized surface-plasmon resonances (LSPRs). Numerical calculations are performed through the 3D Green's Theorem method to obtain the absorption and scattering cross sections for Au nanoparticles with star-like shape of varying symmetry and tip number. Their unique thermoplasmonic properties, with regard to their (red-shifted) LSPR wavelentgh, (∿ 30-fold increase) steady-state temperature, and scattering/absorption cross section ratios, make them specially suitable for optical heating and in turn for cancer thermal therapy. © 2011 Optical Society of America. | Descripción: | 6 pags., 3 figs., 1 tab. -- OCIS codes: (240.6680) Surface plasmons; (250.5403) Plasmonics; (170.5180) Photodynamic therapy | Versión del editor: | http://dx.doi.org/10.1364/OE.20.000621 | URI: | http://hdl.handle.net/10261/246702 | DOI: | 10.1364/OE.20.000621 | Identificadores: | doi: 10.1364/OE.20.000621 issn: 1094-4087 |
