TLDR
This advance allows truly diffraction-limited high-resolution imaging over the entire mid-infrared spectrum with high chemical sensitivity and fast acquisition speed while maintaining high-quality SNR.Abstract:
Conventional Fourier-transform infrared (FTIR) microspectroscopic systems are limited by an inevitable trade-off between spatial resolution, acquisition time, signal-to-noise ratio (SNR) and sample coverage. We present an FTIR imaging approach that substantially extends current capabilities by combining multiple synchrotron beams with wide-field detection. This advance allows truly diffraction-limited high-resolution imaging over the entire mid-infrared spectrum with high chemical sensitivity and fast acquisition speed while maintaining high-quality SNR.read more

Infrared spectroscopic imaging advances as an analytical technology for biomedical sciences
Tomasz P. Wrobel,Rohit Bhargava +1 more
TL;DR: 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.

Nanoscale infrared spectroscopy: improving the spectral range of the photothermal induced resonance technique.
TL;DR: This work interfaced a broadly tunable pulsed laser relying on a difference frequency generation scheme in a GaSe crystal to emit light tunable from 1.55 μm to 16 μm with a commercial PTIR instrument and obtained results that notably surpasses the light diffraction limit throughout the entire mid-IR spectral range.

TL;DR: It is reported that the dispersed hydrocarbon plume stimulated deep-sea indigenous γ-Proteobacteria that are closely related to known petroleum degraders, and the potential exists for intrinsic bioremediation of the oil plume in the deep-water column without substantial oxygen drawdown.
