Archer Exploration Limited and the University of Adelaide have developed graphene-based inks that can print electronic circuits for biosensors.
The research is part of the Australian Research Council Research Hub for Graphene Enabled Industry Transformation. The aim of the research is to develop an electrochemical graphene-based biosensor.
The researchers used a combination of public and proprietary methods to create the inks. They used Archer’s Campoona graphite due to its quality.
The team tried the ink with two printers (1) an inkjet printer and (2) a laser scribed printer.
They then obtained the electrochemical characteristics of the printed electrodes. The results showed that the ink is suitable to use in biosensing devices.
However, the researchers are still testing the rheological properties of the inks under the ongoing collaboration.
Archer CEO Dr Mohammad Choucair said: “The work with The University of Adelaide Graphene Hub highlights our continued and successful collaborative efforts in executing our advanced materials and technology strategy, and provides Archer with commercial opportunities to develop high-value graphene products and technologies in the focus area of human health, to underpin further development of our Campoona graphite resource.”
Archer will now use the results of the work to secure intellectual rights for the commercially viable technology.
Graphene inks and printed graphene electronic device products form part of the emerging $2 billion conductive ink technology market, according to Archer’s news release.
The news release also points out that this market will serve niche segments of the global biosensor space, which is expected to grow to $27 billion by 2022.
