General description

  • Vis-IR extinction-peak wavelength: 580-620 nm.
  • Vis-IR extinction-peak OD: 0.6-0.9
  • Vis-IR extinction-peak OD-average: 0.6-0.8.
  • Vis-IR extinction-peak OD-intraslide CV: <15%.
  • Fluorescence enhancement: >50 times at 800 nm.

Application

Our gold coated slides contain ~100 nm thick film of nanostructured plasmonic gold particles and find applications as fluorescence enhancing substrates for many fluorophores emitting in the 600-1700 nm range, including Cy5, Alexa Fluor™ 647, IRDye® 800 and others. These gold substrates can also be used to enhance Raman scattering signals. Using these slides an enhancement in Raman signal up to 100-fold can be achieved at ~800 nm emission channel. A 5-10 fold increase in scattering can be obtained in the visible light range. These slides are also capable of enhancing surface Raman scattering signals up to 107 fold.

Other Notes

Quantity: 5 slides (per 1EA).

Protein chips are widely used for high-throughput proteomic analysis, but to date, the low sensitivity and narrow dynamic range have limited their capabilities in diagnostics and proteomics. Here we present protein microarrays on a novel nanostructured, plasmonic gold film with
