Journal ArticleDOI
Chemical imaging of biological tissue with synchrotron infrared light
Lisa M. Miller,Paul Dumas +1 more
TL;DR: The development of synchrotron-based FTIRM is described, its advantages in many applications to biological systems are illustrated, and some potential future directions for the technique are proposed.
Journal ArticleDOI
Resonant Mie Scattering (RMieS) correction of infrared spectra from highly scattering biological samples
Paul Bassan,Achim Kohler,Harald Martens,Joe Lee,Hugh J. Byrne,Paul Dumas,Ehsan Gazi,Michael D Brown,Noel W. Clarke,Noel W. Clarke,Peter Gardner +10 more
TL;DR: In this paper a preliminary algorithm for correcting RMieS is presented and evaluated using simulated data and results show that the 'dispersion artefact' appears to be removed; however, the correction is not perfect.
Journal ArticleDOI
Resonant Mie scattering in infrared spectroscopy of biological materials--understanding the 'dispersion artefact'
TL;DR: In this article, the authors use synchrotron radiation FTIR micro-spectroscopy to record spectra of mono-dispersed poly(methyl methacrylate) (PMMA) spheres of systematically varying size and demonstrate that the spectral distortions in the data can be understood in terms of resonant Mie scattering.
Journal ArticleDOI
Highly resolved chemical imaging of living cells by using synchrotron infrared microspectrometry.
Nadège Jamin,Paul Dumas,Janine Moncuit,Wolf H. Fridman,Jean-Luc Teillaud,G. L. Carr,Gwyn P. Williams +6 more
TL;DR: Using synchrotron radiation as an ultra-bright infrared source, the distributions of functional groups such as proteins, lipids, and nucleic acids inside a single living cell with a spatial resolution of a few microns are mapped.
Proceedings ArticleDOI
Magnetorheological finishing (MRF) in commercial precision optics manufacturing
TL;DR: The magnetorheological finishing (MRF) as mentioned in this paper is a sub-aperture lap process that requires no specialized tooling, because the magnetically-stiffened abrasive fluid conforms to the local curvature of any arbitrarily shaped workpiece.
