We report Fourier transform infrared spectro-microtomography, a nondestructive three-dimensional imaging approach that reveals the distribution of distinctive chemical compositions throughout an intact biological or materials sample. The method combines mid-infrared absorption contrast with computed tomographic data acquisition and reconstruction to enhance chemical and morphological localization by determining a complete infrared spectrum for every voxel (millions of spectra determined per…

This work reports unique data evidence that 3D thermo-chemical information in complex semi-transparent media can be obtained using the proposed 3DITI method, and presents new problems in the acquisition, storage and processing of big data.

Spatially Resolved Two-Dimensional Infrared Spectroscopy via Wide-Field Microscopy.

The first wide-field microscope for measuring two-dimensional infrared (2D IR) spectroscopic images is reported, which has diffraction-limited spatial resolution and enhanced contrast compared to FTIR microscopy and is found to have nonlinear scaling of the 2D IR signal to the absorptivity coefficient for the vibrational modes.

Infrared Spectroscopic Imaging Advances as an Analytical Technology for Biomedical Sciences.

The combination of vibrational mid-infrared (IR) spectroscopy and microscopy is especially attractive since the fundamental vibrational modes of samples are coincident with optical frequencies, thereby absorbing a large fraction of incident light and providing a strong signal.

3D Quantitative Chemical Imaging of Tissues by Spectromics.

Three-dimensional mid-infrared tomographic imaging of endogenous and exogenous molecules in a single intact cell with subcellular resolution.

A method and protocols are provided that overcome the challenge in which tilt-series infrared tomography is used with a standard benchtop infrared microscope and gives access to the quantitative 3D distribution of molecular components based on the intrinsic contrast provided by the sample.
