Scientists captured clear images of biomolecules in single live cells in water for the first time using infrared (IR) transmission imaging. The IR technique enables researchers to measure the mass of ...

Water vapour continuum absorption refers to the smooth, broadband absorption observed in the atmospheric windows, which fills the spectral gaps between distinct molecular absorption lines. This ...

If you were to use infrared (IR) transmission microscopy, you would appreciate its chemical quantification abilities—unless your object of study was a hydrated cell. In that case, you might complain ...

Imaging live cells without disrupting their natural behavior or damaging their structures is one key challenge in biomedical optics, and has been tackled in multiple ways. A project at NIST has now ...
