Synchrotron radiation based Fourier transform IR (SR‐FTIR) spectromicroscopy allows the study of individual living cells with a high signal to noise ratio. Here we report the use of the SR‐FTIR technique to investigate changes in IR spectral features from individual human lung fibroblast...
A novel thiol‐specific spin labeling procedure for the protein component (apoprotein B, apoB) of low density lipoproteins (LDLs) is presented. A methanethiosulfonate spin label was used to probe the free cysteine residues of apoB with electron paramagnetic resonance (EPR) spectroscopy. The...
The zinc(II)–L‐carnosine system was investigated at different pH and metal/ligand ratios by Raman and IR spectroscopy. The Raman and IR spectra present some marker bands useful to identify the sites involved in metal chelation at a specific pH value. In particular, the neutral imidazole group...
A new molecular nonbonded interactions treatment strategy is proposed in the context of rectangular periodic boundary conditions simulations. Several molecular dynamics simulations are performed on a sodium ion in aqueous solution. Box sizes are modified from a cubic to a rectangular shape. The...
This work determined that the percentage of suberin in cork may be found by solid‐state 13C cross polarization/magic angle spinning (CP/MAS) NMR spectroscopy and by FTIR with photoacoustic detection (FTIR‐PAS) spectroscopy. A linear relationship is found between the suberin content measured...
A chemiluminescent method is described for the determination of tetracycline, chlortetracycline, minocycline, doxycycline, and demeclocycline. The method is based on the photon counting technique and the spline functions approximation. The simple formula S = b + Ax2 is proposed for the observed...
Annealing of “thick” metal films deposited onto a smooth dielectric substrate leads to high‐order self‐organization of metal clusters on the film surface. This work presents the first experimental evidence that the “thick” gold film (TGF) may be specifically annealed to serve as a...
