Twenty years ago, scientists announced the creation of a new miracle substance that would revolutionize our lives. They named it graphene.
Graphene is made up of a single layer of carbon atoms arranged in a hexagonal pattern, making it one of the strongest materials ever produced. It is more resistant to electricity than copper and has excellent heat conductivity.
The potential applications of graphene seemed limitless, with predictions of ultra-fast processors, quicker battery charging, and stronger concrete. It was even proposed as a solution for potholes in roads.

The scientists behind the discovery, Andre Geim and Konstantin Novoselov, received the Nobel Prize in Physics in 2010 for their work. The National Graphene Institute was established at the University of Manchester.
Despite the initial hype, the graphene revolution has not materialized as expected. Challenges in scaling up production have hindered its widespread adoption.
Sir Colin Humphreys, a materials science professor at Queen Mary University of London, pointed out that the main issue lies in the difficulty of producing graphene on a large scale.
He explained that the original method of creating graphene was not conducive to mass production and that significant investments by companies like IBM, Samsung, and Intel have been made to develop scalable production methods.
Recent advancements in manufacturing techniques show promise for the resurgence of graphene technology. Companies like Paragraph are now producing graphene-based devices in large quantities.

Graphene-based devices are being used for various applications, including sensors for detecting magnetic fields and differentiating between bacterial and viral infections.
Additionally, graphene devices are expected to be more energy-efficient than current technologies, offering a promising future for the material.
While the graphene revolution may have been delayed, it holds the potential to address pressing global challenges and significantly impact modern life.
Graphene “has the potential to make a real difference to modern life,” says Sir Colin Humphreys, professor of materials science.
