Academic round-up: lighting up cancer cells with quantum dots and improving graphene biosensors with gold

Researchers have used quantum dots to light up cancer cells during surgery, a team have improved graphene biosensors with gold and scientists have created a lens from graphene oxide.

Our academic round-up is an overview of the most important research results in the new materials sector, covering quantum dots, graphene and bioplastics.

Highlighting cancer tumours with quantum dots. Researchers have developed a method to use quantum dots to ‘light up’ cancer cells during surgery so that surgeons are able to determine if the tumours have been entirely removed. The team from Drexel University also believe the technology could be employed in gene therapy. Read more >

Graphene oxide optical lenses.
Researchers have developed and ultra-thin, flat and lightweight optical lens from graphene oxide. The team from the Swinburne University of Technology and Monash University believe the 200 nm lens will open up new avenues in non-invasive 3D biomedical imaging, photonics and micromachines.

Improving graphene biosensors with gold.
Scientists have used gold to improve the performance of biosensors made from graphene oxide. According to the researchers, the biosensor exhibits 3.7 times more sensitivity than biosensors made from graphene alone. The team from the Moscow Institute of Physics and Technology believe the sensor could significantly speed up the process of drug development. Read more >
