Graphene/2D-Metal Hybrids for Improved Sensor Performance

Penn State University Technology Overview
The technology is based on creating atomically thin metals by sandwiching the metal atoms between a substrate and graphene. The unique structure of the metal atoms creates a strong plasmon resonance in the visible/near-IR wavelengths and extreme non-linear optical properties that are >2000x better than gold nanoparticles. These materials will enable unprecedented sensitivity and precision in spectroscopic detection of chem/bio molecules. Beyond the optical properties, this technology will enable new forms of plasmonic metasurfaces, plasmon-enhanced catalysis, and even next-generation quantum technologies.

Stage of Development

Technology Readiness Level (TRL): 4‑7

Applications
This technology is the active surface of specially engineered “microscope slides” that is proven to boost the spectroscopic signal of viruses and molecules by 100-1000x, enabling rapid and reliable identification of biological and chemical molecules for health, environment, and defense applications.
Opportunity
The researchers are seeking licensing opportunities and research collaboration.
