Molecules can be identified by their energy absorption characteristics. Infrared wavelengths can be used for in situ chemical analysis based on their interactions with specific chemical bonds. We are using synchrotron FTIR spectroscopy to characterize maturation-related changes in Aspergillus nidulans hyphae at NSLS (Brookhaven, NY), SRC (U Wisconsin-Madison) and CLS (U Saskatchewan).
Photomicrographs and FTIR spectra acquired along hyphae of permissive (a) and restrictive (b) A. nidulans hypA1 phenotypes. Scale bars 50 µm.

The image below was collected at NSLS.
