Titania-coated gold nanorods with expanded photocatalytic response

New communication in the Journal Nanoscale, from the Royal Society of Chemistry by NFP Group, coordinator of Unit 9 of NANBIOSIS.

Jesús Santamaría, Scientific Director of Unit 9 of NANBIOSIS together with other authors of the Nanostructured Films and Particles (NFP) Group, coordinator of Unit 9 of NANBIOSIS, has published on February 7, 2017, a Communication in the Journal Nanoscale, from the Royal Society of Chemistry.

The syntheses of materials during the research have been performed by the Platform of Production of Biomaterials and Nanoparticles of the NANBIOSIS ICTS, more specifically by the Nanoparticle Synthesis Unit, as stated in the publication.

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.

Multifunctional biomaterials and nanomaterials: the new technological revolution.

CaixaForum Zaragoza, Wednesday, January 18th, 2017 at 7:00 pm: talk by Jesús Santamaría, Scientific Director of Unit 9 of NANBIOSIS, within the Conference Cycle: Technology, the permanent revolution

Nanotechnology is the application of nanoscience and, in its modern conception, implies having the ability to design nanomaterials for a specific purpose and to control the manufacturing processes that allow them to have the desired characteristics (composition, size, shape, surface characteristics).

This talk presents the developments in nanotechnology as a true technological revolution. The general concepts and the influence of nanotechnology in our lives shall be discussed with examples of recent advances, with special emphasis on those obtained in the Institute of Nanoscience of Aragon and Unit 9 of NANBIOSIS including with applications in the field of nanomedicine.

Award to research with micronanotechnology.

The Royal Spanish Academy of Engineering has awarded a medal to Víctor Sebastián Cabeza, researcher of the group “Nanostructured Films and Particles”, which coordinates Unit 9 of NANBIOSIS.

The prize has been awarded in recognition of his work in designing a wide variety of micro-reactors to produce nanomaterials in a controlled and successful manner, reducing time and costs, with applications in Biomedicine, catalysis or energy processes.

Dr Víctor Sebastián also received the prestigious Fulbright scholarship in 2009 to carry out a postdoctoral research at the Massachusetts Institute of Technology (MIT) on nanomaterials and its development in microfluidics and in 2014 the European Academy awarded him the Burgen Scholarship Award recognizing him as one of the young researchers with greater scientific projection. Victor works in the field of micronanotechnology for its application in Biomedicine, Catalysis or energy processes. In particular, it has designed a large variety of micro-reactors with sub-millimeter dimensions that allow very precise control of the reaction conditions of the chemical processes that take place in them.

Dr Sebastian is an active member of Unit 9 of Nanobiosis, where he develops microfluidic system for biomedicine that allow a highly precise synthesis of nanomaterials.

4 Units of NANBIOSIS hosted in three Universities among the 200 best in the world in science.

The University of Zaragoza is one of the 200 best universities in the world in science research, according to the latest Shanghai ranking of 2016 in a specific analysis by macro areas.

In order to elaborate this ranking by macroareas indicators such as the number of students and professors who have obtained the Nobel prize or Fields medal, the number of researchers highly cited in the scientific literature, the number of scientific articles indexed in the Science Citation Index and the Percentage of articles published in the most cited 20% scientific journals are used.

Only six Spanish universities are among the 200 best in the world in the field of science, such as the Autonomous University of Madrid, University of Barcelona, University of Santiago de Compostela, Polytechnic University of Valencia, University of Valencia and Zaragoza.

The list of the world’s top 200 universities in science is headed by American universities in Berkeley (California), Stanford, Princeton, Harvard, the Massachusetts Institute of Technology and California, which rank the top six. In the seventh one appears the first European university, Cambridge, followed by the one of Tokyo, Technological Institute of Switzerland and the University of Los Angeles.

NANBIOSIS contributes to this success through the elite researchers that coordinate three of its Units located in the University of Zaragoza: Unit 9 that offers services for sciences research as Synthesis of Nanoparticles biomedicine, micronanotechnology or microfluidics biomedicine, Unit 13 with services as tissue and biomaterial characterization or mechanical tests of tissues and Unit 27 which offers services for sciences research on biomedical computer simulation, modelling of biomedical systems or large simulation multicore and multiserver, among other aspects.

In addition, the Polytechnic University of Valencia and the University of Valencia provides the scientific management and part of the equipment to Unit 26 of NANBIOSIS that offers services for research as molecular imaging metabolomics by NMR or metabolic profiling of biofluids by NMR

Three Universities among the 200 best in the world in science, hosting 4 Units of NANBIOSIS.

The Conferences in Nanotechnology of major reference at Spanish level.

Last November, 7th, the 10th AIN Conference on Industrial Applications of Nanotechnology, held in Zaragoza, brought together experts from research centres, universities and companies on the Industrial Applications of Nanotechnology. Among  them Jordi Reverter, Head of Knowledge and Technology Transfer of ICN2, (Institute housing  Unit 4 of NANBIOSIS) and Ricardo Ibarra, director of Institute of Nanoscience of Aragon (INA) which houses Unit 9 of NANBIOSIS) .

Joan Parra, director of the technology centre LEITAT  of  Catalonia, described the event as “Conferences of greater reference at Spanish level in Nanotechnology

During the meeting, their experience with nanotechnology was shown by the ICTS Elecmi and companies such as Grupo Antolín, Samca Group, BSH Electrodomésticos, Cepsa, Argenol Laboratories and Graphene Nanotech.

Dr. Jose L. Hueso (Unit 9 of NANBIOSIS) presented a recently patented nanocatalyst with great potential for its application in both biomedical and petrochemical fields.
