MESOPHOTONICS Ltd (UK)
Mesophotonics are a novel company based in the UK producing a range of ancillary items for Raman Spectrometry.
Mesophotonics provides trace level detection solutions for applications including drug development, forensic detection, medical diagnostics, homeland security and general analytical chemistry.
The company’s principle products are Klarite® substrates for surface enhanced Raman spectroscopy (SERS) offering unparalleled levels of reproducibility and signal consistency enabling rapid detection to parts per billion level. Klarite is designed around photonic crystal enhanced nano-structured surfaces and its design builds on over 30 man years of experience in photonic crystal design and fabrication.
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. Surface enhanced Raman technology (SERS) increases the
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 process.
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 work in conjunction with the Raman Systems hand held units available from B.E.S.T . 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.
