Tuning the Plasmonic Response up: Hollow Cuboid Metal Nanostructures 2016 Access copy available to the general public Unrestricted We report the fine-tuning of the localized surface plasmon resonances (LSPRs) from ultraviolet to near-infrared by nanoengineering the metal nanoparticle morphologies from solid Ag nanocubes to hollow AuAg nanoboxes and AuAg nanoframes. Spatially resolved mapping of plasmon resonances by electron energy loss spectroscopy (EELS) revealed a homogeneous distribution of highly intense plasmon resonances around the hollow nanostructures and the interaction, that is, hybridization, of inner and outer plasmon fields for the nanoframe. Experimental findings are accurately correlated with the boundary element method (BEM) simulations demonstrating that the homogeneous distribution of the plasmon resonances is the key factor for their improved plasmonic properties. As a proof of concept for these enhanced plasmonic properties, we show the effective label free sensing of bovine serum albumin (BSA) of single-walled AuAg nanoboxes in comparison with solid Au nanoparticles, demonstrating their excellent performance for future biomedical applications. info:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 6.756 2016 MATERIALS SCIENCE, MULTIDISCIPLINARY 28 / 275 = 0.102 2016 Q1 T1 OPTICS 7 / 92 = 0.076 2016 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 15 / 87 = 0.172 2016 Q1 T1 PHYSICS, CONDENSED MATTER 14 / 67 = 0.209 2016 Q1 T1 PHYSICS, APPLIED 16 / 147 = 0.109 2016 Q1 T1 3.471 2016 Atomic and Molecular Physics, and Optics 2016 Q1 Electronic, Optical and Magnetic Materials 2016 Q1 Electrical and Electronic Engineering 2016 Q1 Biotechnology 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Patarroyo, J.
