New research shows graphene can be developed and used safely

Researchers from Edinburgh and Manchester Universities said that there has been a surge of interest in developing graphene for applications including electronics, phone screens, clothing, paints and water purification.

Specifically, graphene is actively being explored globally to assist with targeted therapeutics against cancer and other health conditions, and also in the form of implantable devices and sensors, according to the researchers.

This study aimed to test inhalation of a specific type of graphene – thin, ultra-pure graphene oxide, a water-compatible form of the material – before it could be considered for medical use.

Researchers found that carefully controlled inhalation of the nanomaterial has no short-term adverse effects on lung or cardiovascular function.

In a statement, Dr Mark Miller, from Edinburgh University's Centre for Cardiovascular Science, said: “Nanomaterials such as graphene hold such great promise, but we must ensure they are manufactured in a way that is safe before they can be used more widely in our lives.
