Mid-infrared (IR) spectroscopic imaging using inherent vibrational contrast has been broadly
used as a powerful analytical tool for sample identification and characterization. However …

Midinfrared photothermal (MIP) microscopy, also called optical photothermal infrared (O-
PTIR) microscopy, is an emerging tool for bond-selective chemical imaging of living …

Chemical imaging, especially mid-infrared spectroscopic microscopy, enables label-free
biomedical analyses while achieving expansive molecular sensitivity. However, its slow …

Owing to its capacity for unique (bio)-chemical specificity, microscopy with mid–infrared (IR)
illumination holds tremendous promise for a wide range of biomedical and industrial …

Infrared (IR) imaging provides chemical-specific information without the need for exogenous
labels. Conventional far-field IR imaging techniques are diffraction limited, which means an …

Mid-infrared photothermal microscopy is a new chemical imaging technology in which a
visible beam senses the photothermal effect induced by a pulsed infrared laser. This …

Label-free, bond-selective imaging offers new opportunities for fundamental and applied
studies in chemistry, biology, and materials science. Preventing its broader application to …

Infrared (IR) imaging has become a viable tool for visualizing various chemical bonds in a
specimen. The performance, however, is limited in terms of spatial resolution and imaging …

Electrocatalytic conversion of widely distributed nitrate from industrial wastewater into value-
added ammonia was proposed as an attractive and sustainable alternative to harvesting …

We report a confocal interferometric mid-infrared photothermal (MIP) microscope for ultra-
sensitive and spatially resolved chemical imaging of individual viruses. The interferometric …
