A modular Raman microspectroscopy system for biological tissue analysis

Confocal Raman Microspectroscopy; Applications in Cartilage Tissue Engineering

Raman microspectroscopy for non-invasive biochemical analysis of single cells.

Recent developments in biomedical vibrational spectroscopy now permit the non-invasive imaging of cells and tissues within both the laboratory and clinical settings. The rapid nature and diagnostic potential of both Raman and FTIR (Fourier-transform IR) spectroscopy have resulted in their widespread application to a number of biological fields including fundamental cell biology, medical imaging...

Multifocus confocal Raman microspectroscopy for rapid single-particle analysis.

We have developed a multifocus confocal Raman microspectroscopy system that allows simultaneous analyses of ≈ 80 individual biological or airborne microparticles based on a precise image-guided technique. Multiple individual particles adhered in random positions on a coverslip were illuminated by a multifocus excitation pattern formed by rapidly steering a single laser beam with a pair of galvo...

Effect of substrate choice and tissue type on tissue preparation for spectral histopathology by Raman microspectroscopy.

Raman spectroscopy is a non-destructive, non-invasive, rapid and economical technique which has the potential to be an excellent method for the diagnosis of cancer and understanding disease progression through retrospective studies of archived tissue samples. Historically, biobanks are generally comprised of formalin fixed paraffin preserved tissue and as a result these specimens are often used...

Raman Microspectroscopy of LiDNA Fibres

The conformation of low-salt LiDNA in fibrous form has been studied by Raman microspectroscopy. The recorded spectrum of a fibre soaked in ethanol is very similar to that of a fibre at low relative humidity. From x-ray experiments it is known that in the latter case the DNA adopts the C conformation. Therefore, it can be concluded that this is also the case in a low-salt LiDNA fibre soaked in e...
