What we do
The Rivnay Group at Northwestern University engineers organic bioelectronic materials, devices and systems for interfacing between the complex world of biology and traditional optoelectronics.
Our interests involve understanding the unique active properties of organic (small molecule and polymeric) materials, including mixed ionic–electronic conduction and actuation, and utilizing their strengths for sensing and stimulation in biomedical settings. These fall into four areas, with applications ranging from probes for neural engineering to in vitro platforms and regenerative scaffolds.
Living electronics
Bioelectronics meets synthetic biology: biohybrid devices that regulate engineered cells as living therapeutics.
Fundamentals & materials design
How organic mixed ionic–electronic conductors work, and how to design new ones for performance and stability.
Sensors & circuits
Organic electrochemical transistors and hybrid circuits for physical, electrical, and chemical sensing.
Applications
Implantable and wearable devices, regenerative engineering, and in vitro platforms.
