Micromotors made easy

Researchers of the ICN2 Nanobioelectronics and Biosensors Group led by Prof. Arben Merkoçi have devised a simple manufacturing method for versatile graphene oxide-based micromotors. Requiring no specialist equipment, it can be used to produce a range of micromotors that can be further tuned for different purposes. Luis Baptista-Pires explains the process in the paper published in Small.

ICN2 in the Media: On flexoelectricity and bone repair

Last month ICN2 researchers revealed how a physical phenomenon at the nanoscale, flexoelectricity, stimulates the biological process of bone self-repair. Their paper, "Flexoelectricity in Bones", was published in Advanced Materials on 19 January. Helped along by an ICN2 press conference held in Barcelona, it has since drawn considerable attention from the media.

A nanophenomenon that triggers the bone-repair process

Researchers of the ICN2 Oxide Nanophysics Group led by ICREA Prof. Gustau Catalan have resolved one of the great unknowns in bone remodelling: how the cells responsible for forming new bone tissue are called into action. Their work reveals the possible role of an electromechanical phenomenon at the nanoscale, flexoelectricity, not only in stimulating the cell response, but in precisely guiding it throughout the fracture repair process.

How graphene can transform brain-computer interfaces

ICN2 group leader ICREA Prof. Jose Antonio Garrido and fellow Graphene Flagship programme coordinator, Prof. Kostas Kostarelos of the University of Manchester, were invited by Advanced Materials to present their vision of the role of graphene in the design of advanced brain-computer interfaces. Published earlier this month, the work entitled “Graphene in the design and engineering of next-generation neural interfaces” outlines the current state-of-the-art in this field, along with the ways graphene is allowing us to overcome some of the obstacles to fully realising the next generation of neural interfaces.

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.
