Klarite Surface Enhanced Raman
Klarite substrates provide a unique solution for surface enhanced
Raman spectroscopy (SERS). Unrivalled levels of Raman signal reproducibility
are obtained by using these substrates.
Klarite substrates feature a systematically designed nanometre
scale patterning of the Gold surface. Made of regular arrays of
holes the surface patterns form photonic crystals which control
the surface plasmons that govern the SERS amplification. By leveraging
its experience in photonic crystal design Mesophotonics is able
to control the surface plasmon effects and therefore control the
is built into Klarite slides by using volume manufacturing procedures
from the semiconductor industry. Tests have shown relative standard
deviations (RSD) of <15% are achieved with only 5mW excitation
at 633nm or 785nm. This includes all variations between different
chips without any data selection or filtering. Across a single chip
variations of just 6% RSD have also regularly been recorded.
To increase ease of use, this latest generation of SERS substrates
come mounted on common 75x25mm microscope glass slides compatible
with most micro Raman spectrometers. The active area is 5x5mm with
larger areas available on request.
