Circular Plasmonic Mach-Zehnder Interferometer

SUMMARY

Lehigh University has developed a compact plasmonic Mach-Zehnder interferometer (MZI) integrated on a microfluidic chip for highly sensitive optical biosensing.

 

This technique combines nanoplasmonic architecture and sensitive interferometric techniques on a compact sensing platform for enhanced refractive index sensitivity. The inventors have demonstrated real-time, label-free, quantitative monitoring with high signal-to-noise ratio.

 

This technology is primarily applicable to mobile and remote uses. Lehigh Tech ID# 090811-01

 

This technology is protected by a United States Patent Application.

THE MARKET

The worldwide market for biosensors was $6.72 billion in 2009, growing at an annual rate of over 11% until 2016, where it is estimated to reach $14.42 billion.[1] Applications for biosensors are growing, increasing demand and revenues for these technologies. [2] There is also a push in the market for miniaturized biosensor devices in order to integrate them into portable systems, providing a window of opportunity for new technologies entering the market with such an “on-chip” focus.
