|What is Klarite?
Klarite substrates from Mesophotonics provide
a unique solution for analysing and identifying chemical compounds
through Surface Enhanced Raman Spectroscopy (SERS).
Raman analysis provides a unique fingerprint spectra
of the compound under investigation, that provides both compositional
and structural information. SERS increases the already defined magnitude
of the normally very weak Raman signals by over a 1,000,000 times.
The unique Klarite technology makes this enhancement of the Raman
signal reproducible enough to be used in everyday chemical analysis
for a wide range of applications, from medical diagnosis and drug
discovery to forensics and homeland defence.
Klarite substrates feature a systematically designed nanometre scale
patterning of a silicon surface that is coated in gold. Made of regular
arrangements of holes, the surface patterns form photonic crystals
that control the surface plasmons that govern the Raman enhancement
Using Mesophotonics' experience in photonic crystal design Klarite
substrates enable the control of surface plasmon effects and therefore
control of the Raman amplification.
Reproducibility is a key feature of Klarite slides, which are produced
using volume manufacturing procedures from the semiconductor industry.
Semiconductor fabrication processes enable large volumes of identical
SERS substrates to be produced, making Klarite an affordable and accessible
test for a range of analytical applications.
Klarite products need to be used with a Raman Spectrometer, and there
are several types of instrument available depending on your applications.
To increase ease of use, this latest generation of Klarite substrates
are available mounted on common 75x25mm microscope glass slides -
which are compatible with most micro Raman spectrometers - and as
unmounted chips. The active SERS area is 4x4mm, with larger areas
available on request
