Helping Medicine with Graphene Quantum Dots

Researchers from the University of Sydney have recently published their findings that quantum dots made of graphene can improve bio-imaging and LEDs.

The study was published in the journal Nanoscale, where the scientists detailed how activating graphene quantum dots produced a dot that would shine nearly five times bright than the conventional equivalent.

Essentially, the dots are nano-sized semiconductors, which are fluorescent due to their surface properties. However, this study introduces the utilization of graphene in the quantum dot, which produces an extra-bright dot that has the potential to help medicine.

The quantum dots in solution could also be injected into the body to bind to and detect cancer cells, the researchers say.

Graphene quantum dots would offer a relatively non-toxic alternative to current quantum dots proposed for use in the body.

Dr. Vincent Gomes, a physicist at the University of Sydney and an author of the study, believes this finding will be more efficient than the current standard for bio-imaging.

“Because they are made of carbon they are expected to be non-toxic and biodegradable,” said Gomes.

Aside from bio-imaging, the graphene quantum dots have electricity potential – with the ability to assist in making long-life batteries that charge and discharge in a matter of minutes instead of hours.
