Surface Enhanced Raman Scattering -a powerful sensing application

Surface Enhanced Raman Scattering -a powerful sensing application

4n4SERS
 
4n offers SERS substrates to enhance your Raman signal significantly and consequently help to lower the Limit of Detection (LoD). The SERS substrates are manufactured with 4n's proprietary nanoparticles, guaranteeing highest quality level and avoiding batch to batch variations. The substrates are optimized for the wavelength range of 500 - 800 nm.

4n4SERS

01 | SECURE
 
Robust and easy to use. With their EXTREMELY HIGH DAMAGE THRESHOLD of > 3kw/cm², 4n4SERS substrates won't let you down, even with when full power of your 500 mW Raman laser is utilized for best results.

Threshold

02 | SENSITIVE
 
Distinct strong LOCALIZED SURFACE PLASMON RESONANCE (LSPR) effect of HighQuant nanoparticles un-locks orders of magnitude improvement of the limit of detection. Figure: Raman signal of 0.1 ppm Melamine in H2O

Limit of Detection

03 | REPRODUCIBLE
 
Reproducibility of the utilized nanoparticles significantly improves the SPOT TO SPOT REPRODUCIBILITY and thus speed, cost and reliability of the characterization. Figure: spot to spot deviation of the Raman signal of < 12%, close to the LoD.

Reproducibility

The product is based on results of a  'Beyond Europe' program, sponsored by the Austrian Federal Government in collaboration with the Austrian Research Promotion Agency FFG
