Irregulary-shaped Metal Nanoparticles For Photonics And Sensing Applications

Description
We are developing irregulary-shaped metal nanoparticles for photonics and sensing applications. The crescent particles are expected to behave as polarization-sensitive optical antenna that can be tuned by controlling the particles’ structural properties. By tailoring the optical properties and controlling the surface chemistry, we are developing the particles into a sensing platform for biomolecule recognition studies.

Implications
The crescent-based sensing platform should have an impact in medical research and diagnostics, drug discovery, and fundamental molecular and cellular biology investigations by providing versatile, label-free, sensing methods with high sensitivity and the ability to perform parallel, high-throughput, real-time analysis based on multiplexing. In addition to chemical and biological sensing, the nanoparticles should have application in surface-enhanced spectroscopies and potential as a basis for left-handed materials development.
