“MatoS & RandaS” are fresh, new SERS substrates cooked up by Ato ID

Ato ID has issued performance and application details for their next-generation of disposable glass substrates for Surface Enhanced Raman Spectroscopy (SERS) and/or Surface Enhanced Fluorescence (SEF).

The new smaller AtoID ‘MatoS’ gold and ‘RandaS’ silver Plasmonic Sensor Substrates are available in addition to the existing 1″ square ‘Randa’ and ‘Mato’ ranges and continue to deliver up to 8x more sensitivity than leading rivals.

These new ½” long small form factor slides are individually vacuum packed in 1.5 ml microcentrifuge tubes enabling easier handling for fresh, on-the-spot analysis of immersed material.

  • Size: 12.5 x 5 x 1 mm
  • Active area: 3 x 5 mm
  • Excitation wavelengths:
    • Silver RandaS: 442 nm to NIR
    • Gold MatoS: 600 nm to NIR

For extra information about these new SERS substrates from AtoID, please contact us.


September 2014 Newsletter Out Now

September 2014 NewsletterThe Elliot Scientific September newsletter is now available. In this issue we look at the new MMP precision micropositioning stage series from Mad City Labs, cover Ato ID’s cost-effective high-performance Gold SERS substrates for an enhanced Raman signal, reveal that Lake Shore’s new Model 372 AC Resistance Bridge/Temperature Controller is now shipping, explain how BOTDR enhances the Foresight™ DSTS from OZ Optics, and look forward to Photonex 2014 in October.

New Gold SERS substrates for enhanced NIR Raman signal

The newly released Ato ID™ ‘Mato’ Plasmonic Sensor is designed to offer good excitation results for Surface Enhanced Raman Spectroscopy (SERS) in both the red (600 nm plus) and NIR wavelength ranges.

Features sers-mato-pack3

  • Ideal for red to NIR laser wavelengths
  • Significantly enhances Raman signal
  • Gold (Au) coated
  • Active area: 4 x 4 mm (typical)
  • Overall carrier size 25 x 25 x 1 mm thick
  • Compatible with use of cover slip over the active SERS area
  • Developed specifically for high sensitivity trace detection applications

The base substrate is soda-lime glass which exhibits relatively weak inherent Raman scattering and so does not interfere with the sample signal. The active region comprises a pure gold coating over the proprietary nanofabricated base (patent pending). The monolithic structure eliminates risk of contaminants that can arise with glued or chemically treated types. All ‘Mato’ Raman substrates are vacuum sealed in a cleanroom environment for ease of handling. Please contact us for more information.
