Next generation graphene-based biosensor for the fast detection of xanthine

  • Xanthinuria is a rare disease caused by the accumulation of xanthine in blood, which can lead to serious pathologies, such as renal failure or gout.
  • ICMAB researchers have prepared a novel hybrid graphene-based electrochemical biosensor for the fast and 100 times more sensitive detection of xanthine, with respect to previously reported sensors.
  • The study, published in the journal Advanced Materials Interfaces, combines the properties of reduced graphene oxide and those of the organic radicals to prepare next generation, low cost electrochemical biosensors.

Spinning the future

The August 2017 edition of the Research*EU magazine featured an interesting overview of the ACMOL project, which is working to develop graphene-based spintronics for next-gen molecular electronic devices. This article held that ‘Spintronics, molecular electronics and graphene have a common trait: they are all considered as key enablers in the future of computing beyond the limitations of Moore’s and Kryder’s laws. The ACMOL project is contributing to their joint advancement with proof-of-concept devices.’

Self-assembly of highly-porous crystalline particles into novel photonic materials for sensing applications

A multi-disciplinary collaboration between research centers in Spain and Holland, led by the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and the Institute of Materials Science of Madrid (ICMM-CSIC), in collaboration with the Debye Institute for Nanomaterials Science of Utrecht University and the Institute of Materials Science of Barcelona (ICMAB), has resulted in the formation of highly-porous metal-organic framework particles that spontaneously assemble into well-ordered 3D superstructures that present photonic crystal properties. Published in Nature Chemistry, their discoveries are expected to find applications in the design of novel photonic materials for sensing applications, among others.

Turning the microscope upside down to measure the piezoelectricity of materials at the nanoscale

ICMAB-CSIC researchers are able, for the first time, to measure the very small amounts of charge generated in piezoelectric materials with an inverse use of the atomic force microscope (AFM). The technique, published in Nature Communications, has been implemented by incorporating a new device to the microscope that allows measuring electric currents one billion times smaller than the ones circulating in an LED.

Imaging how magnetism goes surfing

  • Using ALBA’s synchrotron light, researchers have been able to visualise deformation (sound) waves in crystals and measured the effect on nanomagnetic elements.
  • The study, published today in Nature Communications, uses the accelerators’ time structure to record time resolved images with a resolution of 80 picoseconds.
  • The methodology offers a new approach for analysing dynamic strains in other research fields: nanoparticles, chemical reactions, crystallography, etc.

ICMAB within the Top 10 Institutions in Barcelona according to Nature Index 2017 Science Cities

The Institute of Materials Science of Barcelona (ICMAB-CSIC) is the 7th Top Institution in Barcelona, according to the Nature Index 2017 Science Cities.

This current 12-month Index, corresponding to year 2016, shows Barcelona's leading institutions for high-quality science ordered by the number of articles published (AC) in a list of science journals, and the number of authors of each institution, considering the percentage of authorship in each article (WFC) (with the correction of the centers dedicated to space science, which have a lot of coauthrs in the articles).

Hiding and revealing magnetic information at room temperature

Since the 1950's, magnetic materials have been used to store all kinds of information. The use of magnetic materials is ideal since they allow you to store information for very long periods of time and, moreover, information is easily accessible through well-known reading methods.

However, when storing sensitive information, easy access to information becomes a drawback rather than an advantage, and that's when hiding information becomes a necessity.

Comunicat de les universitats i dels centres de recerca de Catalunya per valorar la situació creada a Catalunya de resultes de les actuacions de l’Estat espanyol en els darrers dies

Avui, 21 de setembre, s’han reunit els màxims representants del conjunt d’universitats i centres de recerca de Catalunya (una seixantena d’institucions que representen prop del 90 % del sistema) per valorar la situació creada a Catalunya de resultes de les actuacions de l’Estat espanyol en els darrers dies. A la reunió hi han assistit també representants dels sindicats i de les associacions d’estudiants.

Iron oxide nanoparticles stress the cells

ICMAB researchers lead a study on the toxicity of iron oxide nanoparticles based on the analysis of specific genetic markers linked to nanotoxicity in the C. elegans organisms.

Part of the experiment, published in the journal Nanotoxicology, has been carried out at the ALBA Synchrotron, in its infrared light MIRAS beamline. The study suggests that nanoparticles can be captured by intestinal cells in their interior, they can interact with cell lipids, and they can activate cellular mechanisms of oxidative stress.
