State of the art on graphene-based biosensors

Biosensing is growing on importance. Nanomaterials and, more specifically, graphene-based platforms have excellent properties for biosensing. In addition, flexible, abundant, low-cost and green materials, such as plastic and paper, can enhance this technology. Graphene-based biosensors will lead to breakthrough solutions for the real world, although their commercialization will imply diverse technical, production and market issues.

Spin Hall effect in decorated graphene

ICREA Prof. Stephan Roche and ICREA Prof. Sergio Valenzuela, Group Leaders at ICN2, in collaboration with researchers from Delaware University and CEA have recently published an article in Physical Review Letters. They question the interpretation of large values from the Spin Hall effect (SHE) signals, reported experimentally in chemically decorated graphene. Further, they propose new device geometry to suppress background contributions on the non-local resistance to access the upper limit of SHE in two-dimensional materials.

Bending semiconductors generates electricity

The discovery, published today in Nature, is a significant breakthrough in solid state physics and is also potentially relevant for technology. The phenomenon, called flexoelectricity, arises from the redistribution of atoms and electrons in a material when it is bent. This redistribution of charges can be used to generate an electrical current. It was already known that insulating materials can be flexoelectric. The surprise discovery is that semiconductors can also be flexoelectric, and moreover they can generate far more electricity than insulators.

A nanoplasmonic biosensor for early detection of colorectal cancer

The ICN2 Nanobiosensors and Bioanalytical Applications Group, led by Prof Laura M. Lechuga, proposed a nanoplasmonic biosensor for colorectal cancer autoantibody detection in an article published in Analytica Chimica Acta. There is an evident need for novel screening tools for a less invasive and more specific screening and diagnosis to fight against this cancer.

An ultrasensitive and specific diagnostic sensor based on interferometric bimodal nanowaveguides 

Researchers from the ICN2 Nanobiosensors and Bioanalytical Applications Group, led by Prof Laura Lechuga, have designed a nanophotonic biosensor for ultrasensitive detection of microRNAs in complex media. Results published in ACS Sensors demonstrate that such devices can be used as an ultrasensitive and specific diagnostic tool for the prediction of diseases (such as cancer) with well-defined microRNA signatures.

Spin lifetime anisotropy of graphene is much weaker than previously reported

An article published today in Nature Communications presents a new method to determine the spin lifetime anisotropy of spin-polarized carriers in graphene using oblique spin precession. The work, led by ICREA research Prof Sergio O Valenzuela, Group Leader of the ICN2 Physics and Engineering Of Nanodevices Group, demonstrates spin-lifetime anisotropy measurements in graphene and discusses them in light of current theoretical knowledge.

Spin manipulation in graphene by chemically-induced sublattice pseudospin polarization

Spin manipulation is one of the most critical challenges to realize spin-based logic devices and spintronic circuits. ICN2 researchers Dinh Van Tuan and ICREA Research Professor Stephan Roche, from the Theoretical and Computational Nanoscience group reveal that certain impurities such as fluorine ad-atoms could result in a remarkable variability of spin transport characteristics in graphene, as published recently in Physical Review Letters.
