Materials – Turning down the heat

Scientists at Oak Ridge National Laboratory and the University of Tennessee designed and demonstrated a method to make carbon-based materials that can be used as electrodes compatible with a specific semiconductor circuitry.

The work bridges nanoscale 3D printing and widely available processes for complementary metal-oxide-semiconductor, or CMOS, technologies to enable biosensors for biomedical applications.

3D printing electrodes on CMOS circuitry from a polymer precursor requires high, yet regulated, temperatures – typically around 900°C – to carbonize the electrode structure. The challenge is to avoid damaging the CMOS chip.

The team’s novel method, performed at the Center for Nanophase Materials Sciences at ORNL, used two photon polymerization and annealing processes to achieve and verify carbonization below 550°.

“We’ve shown that you can convert a polymer to carbon directly on a chip in a way that can be useful for electrochemical sensing,” said ORNL’s Nickolay Lavrik.
