L'oxyde de graphène peut-il se transformer en gouttelettes de cristaux liquides et déboucher sur des systèmes d'administration de médicaments et des biocapteurs ?

Researchers at Monash University discovered that graphene oxide flakes can spontaneously change their structure – becoming liquid crystal droplets in the presence of an external magnetic field.

This could be very useful for applications such as drug delivery and disease detection.

Current drug delivery systems commonly use magnetic particles, which are useful for drug release. However, most magnetic particles are toxic under certain conditions.

The researchers now hope that the new graphene discovery can lead to a better system than what is available today.

The researchers also hope that the same transformation can occur when graphene is exposed to certain toxins – which could mean a system to detect them.
