Renishaw is happy to introduce fluorescence lifetime imaging microscopy (FLIM) performance to its inVia™ confocal Raman microscope. In partnership with Becker & Hickl GmbH, the pioneers in time-correlated single photon counting (TCSPC), the system combines each Raman and FLIM in a single instrument. This integration can overlay each FLIM and Raman photos with pixel-to-pixel correlation, thus rising understanding of samples throughout a variety of purposes.

Within the system, when mild from a pulsed laser interacts with a fluorophore, the fluorescence lifetime is measured utilizing a complicated detector and high-speed electronics. This fluorescence lifetime is the attribute time a fluorophore stays in an excited digital state earlier than returning to the bottom state by emitting a photon. The lifetime of fluorescence decay is delicate to the molecular atmosphere and the ensuing adjustments in molecular conformation. The FLIM approach can be utilized to check a variety of properties from pH/ion/oxygen focus to molecular binding.
Mixed FLIM with Raman microscopy
FLIM and Raman microscopy are complementary strategies for label-free imaging of organic cells and tissue sections. FLIM offers perception into molecular interactions and may be carried out a minimum of 10× quicker than Raman imaging. Raman spectroscopy boasts excessive chemical specificity and high-resolution chemical photos. This mixture of methods is good for speedy identification of areas of curiosity by FLIM, adopted by chemical and structural characterisation by Raman imaging.
For FLIM knowledge evaluation, complete software program from Becker & Hickl is included with multi-exponential, incomplete and shifted-component evaluation fashions. The software program additionally consists of proprietary phasor evaluation to differentiate lifetime populations. Fluorescence lifetime and Raman photos may be straight overlaid attributable to the usage of the extremely correct Renishaw MS30 excessive pace encoded stage for each imaging modalities.
“We’re happy to announce an additional enhancement to our award-winning inVia Raman microscope. Our collaboration with the leaders in FLIM expertise, Becker and Hickl, has produced a mixed FLIM Raman microscope resulting in thrilling new utility areas.”
