BACKGROUND: Chronic periodontitis is an inflammatory disease of the supporting structures of the teeth. Infrared microspectroscopy has the potential to simultaneously monitor multiple disease markers, including cellular infiltration and collagen catabolism, and hence differentiate diseased and healthy tissues. Therefore, our aim was to establish an infrared microspectroscopy methodology with wh...

We report the use of infrared (IR) microspectroscopy for the analysis of fingerprint residues. The advantage of using an IR microscope lies in the ability to visualize and obtain spectra of individual particles and droplets that make up fingerprint ridge deposits at a spatial resolution of approximately 10 microm. Our initial results suggest that infrared microspectroscopy in reflection-absorpt...

At the beginning of 2006, the first infrared microspectroscopy beamline at the Louisiana State University, Center for Advanced Microstructures and Devices (CAMD) storage ring came into operation. The infrared microscope has recently been upgraded with a new liquid nitrogen-cooled mercury–cadmium–telluride detector, MCT-A, and a new dipole chamber to improve the signal-to-noise ratio and extend ...

We characterize individual Ag-TCNQ nanocrystals during switching their resistivity state in operando. Raman and soft X-ray absorption microspectroscopy are employed to disclose the electronic state of the organic component in dependency of applied voltage. Whereas Raman microspectroscopy offers qualitative insight into the conversion of negatively charged TCNQ molecules to their neutral counter...

Raman microspectroscopy is a noninvasive, label-free, and single-cell technology for biochemical analysis of individual mammalian cells, organelles, bacteria, viruses, and nanoparticles. Chemical information derived from a Raman spectrum provides comprehensive and intrinsic information (e.g., nucleic acids, protein, carbohydrates, and lipids) of single cells without the need of any external lab...

In situ synchrotron infrared microspectroscopy on single crystals of SAPO-34 reveals that a carbene insertion mechanism is responsible for the first carbon–carbon bond formation from surface methoxy groups.

www.spectroscopyonl ine.com espite recent advances in Fourier transform-infrared (FT-IR) microspectroscopy and micro-attenuated total reflectance (ATR), for many types of samples there remains a need for even higher spatial resolution, or for a nondestructive method of recording localized mid-IR spectra from asreceived samples without the risk of damage or alteration by preparation techniques. ...

Raman microspectroscopy is employed to monitor the differentiation of mesenchymal stem cells chondrocytes, from subcellular extracellular matrix evolution.

phenobarbital is a phenobarbiturate used as a sedative, anticonvulsant, or hypnotic with the doses prescribed and can cause teratogenic effects. the goal of this study was to examine an alternative method for the recognition of the mechanism or the bimolecular potential changes in mice fetus caused by phenobarbital using ftir micro spectroscopy. the mice were injected with phenobarbital (120mg/...
