Graphenea logoGraphenea is a private European company (based in Spain) focused on the production of high quality graphene for industrial applications. The company produces single-layer graphene sheets, bi-layer graphene, multi-layer graphene, graphene oxide and other materials - on any substrate the customer provides.

In November 2012 the company launched an online store. In 2015, the company announced plans to construct a new graphene pilot plant in a $2.5 million investment.

The project, which lasted two years, aimed at integrating graphene into CMOS semiconductor workflows. The business goal was to create added value through fast-tracking market acceptance of graphene-on-wafer by lowering the technological barriers to adoption of graphene by the €545 billion semiconductor devices industry.

How can graphene assist in the war on Coronavirus?

As researchers and companies all over the world set out to battle the Coronavirus pandemic, many are revisiting graphene as a material with potential for helping to win this fight. The reasons for such potential could be found in graphene's known antibacterial/antiviral properties, its beneficial traits for medical sensors and devices and more.

Graphene has been shown in the past as extremely useful for creating various sensors. Earlier this month, a team led by Boston College researchers used a sheet of graphene to track the electronic signals inherent in biological structures, in order to develop a platform to selectively identify deadly strains of bacteria. In October 2019, Rice University team under chemist James Tour transformed their laser-induced graphene (LIG) into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. Commercially sold graphene-based sensors exist, like the graphene oxide (GO) sensor developed by the ICN2 Nanobioelectronics and Biosensors group that was added in 2016 to the list products offered by Biolin Scientific, a prestigious instrumentation company devoted to the production of analytical devices. The Q-Sense GO sensor enables interaction studies of GO with various analytes (measured substances) of interest and may open the door to various applications with interest for diagnostics, safety/security and environmental monitoring.

Graphenea joins the fight against Covid-19

With the emergence of the Covid-19 virus and its global threat, Graphenea initiated several steps to try and help those trying to combat this crisis. On March 16th, Graphenea approached all those performing research on treatment and diagnosis of Covid-19, to offer free graphene.

Now, Graphenea announced the production of a disinfectant alcohol-based hydrogel following World Health Organization recommendations and pharmaceutical guidelines. As part of its effort to join the battle against COVID-19, Graphenea will donate the hand sanitizer to public authorities for use in hospitals, by seniors, police and/or military personnel. The aim is to protect medical personnel, high risk groups, and law enforcement agents against the virus.

Graphenea launches highly flat monolayer graphene on copper thin film

Graphenea has announced the launch of a new product – highly flat monolayer graphene. The graphene is grown by CVD on copper thin film on a 2” sapphire substrate. With extremely low roughness that is less than 4 nm, this new product is targeted at applications in photonics, high-performance electronics, magnetic memory, and freestanding membranes.

The product aims to meet wafer-scale integration requirements to build uniform graphene devices in a fashion compatible with current industrial fabrication methods. The flat graphene product is ready to be transferred by electrochemical delamination or dry methods since the sapphire substrate is robust enough to withstand mechanical damage, preventing tearing and wrinkling of the thin Cu sheet. The total wafer thickness is 430 micrometers. Full product information can be found in Graphenea's online store.

International team explores graphene-substrate interactions related to surface charges

Due to graphene's 2D geometry, most of the device applications require graphene to be partially or fully supported by a substrate, which is typically silicon dioxide (SiO2). An important example of a typical graphene structure on SiO2 is the graphene field effect transistor – GFET, a sheet of graphene connected to metal terminals on the planar substrate. The current common understanding is that graphene interacts with SiO2 through weak, long-range van der Waals forces, even though experimental evidence suggests a surprisingly strong interaction between graphene and SiO2 that affects all properties of the device.

International team explores graphene-substrate interactions related to surface charges image

Now, a multinational research team from the University of Trento, Italian Space Agency and Fondazione Bruno Kessler in Italy, Graphenea in Spain, Institute of Chemical Engineering Sciences and University of Patras in Greece, and Queen Mary University of London in the UK has shown that surface charges on the oxide are a main factor of strong interaction between graphene and SiO2, paving the way for designing 2D material interaction with a substrate through manipulation of surface charges. Such control of graphene-substrate interactions would facilitate the development of new graphene-based microelectronic devices.
