Optical fiber-based nanosensor probes have been widely developed for compact and high-sensitivity sensing devices for biomedical diagnosis and research and many other applications. However, the complicated and low-throughput fabrication process for the fiber probes (typically involving electron beam lithography and/or focus ion beam lithography) is hindering the technology transition from research laboratories to industrial production and marketing.

Researchers at UAH have developed a low-cost, high-throughput fabrication process that enables the integration of metallic nanostructures on the tips of optical fibers supporting localized surface plasmon resonances. A unique molding and stamping process allows for the fabrication of noble metallic nanodots on the glass tips of the fiber optic sensing probes.

This novel fabrication process would increase manufacturing throughput and aid in this sensing technology’s transition from the lab to the marketplace.
