Technology

Tip-Enhanced Raman Spectroscopy (TERS) is a technique used to measure chemical information about a sample at resolutions as low as 1 nanometer. This technology takes a new approach to TERS by using fiber optics to both deliver and collect light required for raman spectroscopy to an extremely focused area. This is accomplished using a pulled fiber optic that has been coated with plasmonic material at the tip. The plasmonic tip couples with the surface plasmons of the material, allowing light to be added and extracted through the same fiber. Fiber TERS vastly simplifies the technique of TERS when coupled to an atomic force microscope (AFM) or scanning tunneling microscope (STM).

Problem Addressed

Most commercial instruments require significant time to set-up and expertise to operate.

Advantages

  • Significantly reduces setup time

  • Increases speed and accuracy of data collection

  • Maintains compatibility with existing instrumentation

  • Compatible with aqueous samples and environments

  • Minimizes technical services requirement

 

Note - TERS is currently not performed with fiber optics and requires a camera and light source (LASER) to focus independently.  Fiber optics are used for another mostly-unrelated technique called NSOM (near-field scanning optical microscope). However, these lack tip enhancement and are not compatible with aqueous (i.e., biological) samples. 

Applications

This transformative platform technology represents a massive leap in usability and capability for existing TERS applications and potentially expands its use to thermal and biological analysis.

Stage of Development

This proof-of-concept system has been tested with STM to collect data on quantum dots and on wet-lab samples. Inventors are exploring additional spectroscopy approaches including near-field infrared.

TECHNOLOGY READINESS LEVEL:
