BIOLOGICAL materials consisting largely of protein and carbohydrate give rise to infra-red absorption spectra which show the main characteristic absorption bands of the protein and carbohydrate ...

Infrared spectroscopy, which measures light absorption, provides valuable insights into the structure and conformation of biomolecules. When combined with other analytical techniques, Fourier ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

In the last few years, the focus has shifted towards protein in a big way. Yet, as soon as people begin “upping” their protein especially through powders, eggs, paneer, dal, and non-veg sources, ...

To evaluate the purity of nucleic acid and protein samples, molecular scientists frequently compare the recorded spectrophotometric absorbance of a sample at 260 nm to the value measured at 280 nm.

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 ...
