Single Molecule Fluorescence and Tip-Enhanced Raman Spectroscopy (TERS)

A method has been developed to fabricate high-quality, uniform, ultra sharp (10 nm) gold pyramid probe tips. The technique is more reproducible and with a higher yield than current techniques and produces tips with better performance. The pyramids are perfect for use in single-molecule fluorescence imaging, tip-enhanced Raman spectroscopy (TERS) and other near-field imaging techniques.

Uses Template Stripping Fabrication Instead of Focused Ion Beam

Current technology uses slow and expensive nanofabrication tools such as focused ion beam (FIB) or electron-based lithography techniques to produce probes for near-field imaging techniques. The described technique uses template stripping fabrication, which makes the process more reproducible, higher yielding and less expensive.

BENEFITS OF TEMPLATE STRIPPING GOLD PYRAMID PROBE TIPS:

  • Highly reproducible, high-yield technique.
  • Produces ultra-smooth, ultra-sharp probe tips.
  • Ideal for use in single-molecule fluorescence imaging, tip-enhanced Raman spectroscopy (TERS) and other near-field imaging techniques.
  • Less expensive than probes fabricated using other techniques.
