Paper – Quantum cascade laser microscopy of tissue microarrays

Paper – Quantum cascade laser microscopy of tissue microarrays

Large scale infrared imaging of tissue micro arrays (TMAs) using a tunable Quantum Cascade Laser (QCL) based microscope Paul Bassan, Miles J. Weida, Jeremy Rowlette and Peter Gardner Analyst (2014) Abstract Chemical imaging in the field of vibrational spectroscopy is developing into a promising tool to complement digital histopathology. Applications include screening of biopsy tissue via automated recognition of tissue/cell type and disease state based on the chemical information from the spectrum. For integration into clinical practice, data acquisition needs…

Paper – High-throughput tissue imaging

Automated high-throughput assessment of prostate biopsy tissue using infrared spectroscopic chemical imaging Paul Bassan, Ashwin Sachdeva, Jonathan H. Shanks, Mick D. Brown, Noel W. Clarke and Peter Gardner Proc. SPIE 9041, Medical Imaging 2014: Digital Pathology, 90410D 9041 (2014) Abstract Fourier transform infrared (FT-IR) chemical imaging has been demonstrated as a promising technique to complement histopathological assessment of biomedical tissue samples. Current histopathology practice involves preparing thin tissue sections and staining them using hematoxylin and eosin (H&E) after which a…

Paper – FTIR analysis of blood serum

Paper – FTIR analysis of blood serum

Assessing the challenges of Fourier transform infrared spectroscopic analysis of blood serum Caryn Hughes, Michael Brown, Graeme Clemens, Alex Henderson, Geraldine Monjardez, Noel W. Clarke and Peter Gardner Journal of Biophotonics (2014) [OPEN ACCESS] Abstract There are many approaches to measuring the infrared spectrum of a blood serum sample. Naturally, each approach will have both advantages and disadvantages. We report on the progress of the application of infrared spectroscopy in the field of blood serum analysis towards clinical application, with…

Paper – Paraffin removal from FFPE sections

Paper – Paraffin removal from FFPE sections

Assessment of paraffin removal from prostate FFPE sections using transmission mode FTIR-FPA imaging Caryn Hughes, Lydia Gaunt, Michael Brown, Noel W. Clarke and Peter Gardner Anal. Methods (2014) Abstract Formalin-fixed paraffin-embedded (FFPE) tissue sections are routinely analysed for biochemical discrimination by vibrational spectroscopy techniques in the spectral pathology community. In these experiments, it is usually desirable to remove the paraffin from the tissue. This is most commonly performed by the use of xylene but other solvents such as hexane are…

Paper – FTIR through glass

Paper – FTIR through glass

Transmission FTIR chemical imaging on glass substrates: applications in infrared spectral histopathology Paul Bassan, Joe Mellor, Jonathan Shapiro, Kaye J. Williams, Michael Lisanti and Peter Gardner Anal. Chem. (2014) Abstract Fourier transform infrared chemical imaging in transmission mode has traditionally been performed on expensive mid-IR transparent windows such as barium/calcium fluoride, which are more fragile than glass making preparation in the histopathology laboratories more cumbersome. A solution is presented here by using cheap glass substrates for the FTIR chemical imaging…

Paper – Whole organ, label-free imaging

Whole organ cross-section chemical imaging using label-free mega-mosaic FTIR microscopy Paul Bassan, Ashwin Sachdeva, Jonathan H. Shanks, Mick D. Brown, Noel W. Clarke and Peter Gardner Analyst (2013) Abstract FTIR chemical imaging has been demonstrated as a promising technique to construct automated systems to complement histopathological evaluation of biomedical tissue samples. The rapid chemical imaging of large areas of tissue has previously been a limiting factor in this application. Consequently, smaller areas of tissue have previously had to be sampled,…
