Spatial resolution limits for synchrotron-based infrared spectromicroscopy
Detailed spatial resolution tests were performed on beamline 1.4.4 at the Advanced Light Source synchrotron facility in Berkeley, CA. The high-brightness synchrotron source is coupled at this beamline to a Thermo-Electron ContinulmXL infrared microscope. Two types of resolution tests in both the mid-IR (using a KBr beamsplitter and an MCT-A* detector) and in the near-IR (using a CaF2 beamsplitt...
متن کاملSynchrotron-Based FTIR Spectromicroscopy: Cytotoxicity and Heating Considerations.
Synchrotron radiation-based Fouriertransform infrared (SR-FTIR)spectromicroscopy is a newly emergingbioanalytical and imaging tool. This uniquetechnique provides mid-infrared (IR)spectra, hence chemical information, withhigh signal-to-noise at spatial resolutionsas fine as 3 to 10 microns. Thus it enablesresearchers to locate, identify, and trackspecific chemical events within anindividual livi...
متن کاملSpatial resolution limits for synchrotron-based spectromicroscopy in the mid- and near-infrared.
Spatial resolution tests were performed on beamline 1.4.4 at the Advanced Light Source in Berkeley, CA, USA, a third-generation synchrotron light source. This beamline couples the high-brightness synchrotron source to a Thermo-Electron Continumicrom XL infrared microscope. Two types of resolution tests were performed in both the mid-IR and near-IR. The results are compared with a diffraction-li...
متن کاملA sensitive method for examining whole-cell biochemical composition in single cells of filamentous fungi using synchrotron FTIR spectromicroscopy.
Cell function is related to cell composition. The asexual state of filamentous fungi (molds and mildews) has two main life cycle stages: vegetative hyphae for substrate colonization and nutrient acquisition, and asexual spores for survival and dispersal. Hyphal composition changes over a few tens of microns during growth and maturation; spores are different from hyphae. Most biochemical analyse...
متن کاملCombining light microscopy, dielectric spectroscopy, MALDI intact cell mass spectrometry, FTIR spectromicroscopy and multivariate data mining for morphological and physiological bioprocess characterization of filamentous organisms.
Along with productivity and physiology, morphological growth behavior is the key parameter in bioprocess design for filamentous fungi. Lacking tools for fast, reliable and efficient analysis however, fungal morphology is still commonly tackled by empirical trial-and-error techniques during strain selection and process development procedures. Bridging the gap, this work presents a comprehensive ...
