Universidad de Zaragoza (orcid)0000-0001-5835-1223 Titania-coated gold nanorods with expanded photocatalytic response. Enzyme-like glucose oxidation under near-infrared illumination 2017 Gold nanorods coated with a uniform titanium dioxide nanoshell have been prepared and used as glucose-oxidase surrogates. Remarkably, this core-shell photocatalytic nanostructure has been able to induce complete oxidation of glucose at near room temperature (32-34 °C) in a wide range of pH values with the aid of a near-infrared (NIR) irradiation source. In contrast, the uncoated gold nanorods exhibit negligible photo-oxidation response under identical experimental conditions thereby proving the photoactivity of the titania shell towards glucose oxidation. The process takes place via in situ photo-generation of singlet oxygen or hydroxyl radicals as reactive oxidative species (ROS). This underlines the role played by the core nanorods as plasmonic light harvesters in the NIR range and constitutes the first example of a NIR-activated enzyme-like catalyst. info:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626 info:eu-repo/grantAgreement/EC/FP7/294094/EU/Synthesis and characterization of NANOstructured materials with LumInescent properties for diaGnostic and tHerapeuTic applications/NANOLIGHT info:eu-repo/grantAgreement/EC/H2020/642742/EU/Graphene-based nanomaterials for touchscreen technologies: Comprehension, Commerce and Communication/Enabling Excellence This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 642742-Enabling Excellence info:eu-repo/grantAgreement/ES/MINECO/FIS2013-46159-C3-3-P info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.233 2017 MATERIALS SCIENCE, MULTIDISCIPLINARY 30 / 283 = 0.106 2017 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 18 / 91 = 0.198 2017 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 25 / 169 = 0.148 2017 Q1 T1 PHYSICS, APPLIED 15 / 146 = 0.103 2017 Q1 T1 2.934 2017 Nanoscience and Nanotechnology 2017 Q1 Materials Science (miscellaneous) 2017 Q1 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Hueso Martos, José Luis (orcid)0000-0002-4546-4111 Arenal, R.
