Bioengineering is being strengthened in Spain

Estefanía Peña, Scientific Coordinator of Unit 13 of NANBIOSIS explains her resarch in the program “En route with science” of Aragon Television.

Bioengineering consists in the application of the principles of engineering to the field of medicine. In the opinion of Estefanía, coordinator of the Division of Biomedical Engineering and deputy director of I3A (Institute of Research in Engineering of Aragon) Bioingineering is being strengthened in Spain.

“Our research develops mathematical models and computational reproduction, especially of cardiovascular diseases and the therapies to solve them. Fundamentally we work on atherosclerosis, which is the appearance and development of atheroma plaque (a cluster of cholesterol in the wall of an artery)

This is a field with a very important social impact (35% of the deaths in Europe are due to cardiovascular diseases and the annual European cost can be around almost two hundred billion euro), this is why we try to reduce the part of experimentation developing mathematical models, both to understand the biological process, and to design new devices as stems.”

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.
