cisplatin is a common chemotherapeutic agent that used for treatment of many solid cancers. rapid identification of chemotherapy resistance is very important and may lead to effective treatment plan. spectroscopy techniques, such as infrared spectroscopy, which are sensitive to biochemical composition of samples, have shown potentials to discriminate tissues. developing in fourier transform inf...

in this research work, we report a simple method called reflux condensation method for synthesizing co3o4 nanoparticles using cheap chemicals such as, cobalt acetate (precursor salt), sodium monododecyl sulphate - sds (surfactant) and n, n - dimethylformamide - dmf (solvent). the prepared materials were heat treated at 200, 400, 600 and 800 oc for each 2 h to get phase pure product. the calcine...

Polypyrrole (PPy) was synthesized by chemical oxidative polymerization technique using monomer pyrrole and ammonium persulphate as an oxidant in a ratio of 1:1. Thin films of polypyrrole were prepared by dissolving polypyrrole in m-cresol and cast using spin coating technique on glass substrates. Thin films of polypyrrole were characterized by X ray diffraction (XRD), Scanning electron microsco...

in this research the composition of polyurethane closed cell (pucc) with two different concentrations of sio2 nanoparticles (1.0 and 2.0 wt%) have been prepared. optical microscopy and sem imaging, watering uptake, ftir and raman spectroscopy of the synthesized samples were carried out. the optical microscopy imaging of samples showed differences in the appearance of matrix produced by applying...

Genetic evaluation of dairy animals requires rather large datasets, possibly larger than what is feasible to observe directly through chemical analyses for milk composition and quality traits because they are costly and time consuming. An alternative and more convenient method – use of infrared (IR) spectra – has been proposed (Goulden, 1964). Fourier transformed Infrared (FTIR) spectrometry is...

In this paper, FTIR spectroscopy using attenuated total reflection (ATR) and KBr pressed disk techniques has been used to characterize sorbed water and HDTMA+ in organo-clay. Sorbed water content decreases with the intercalation of HDTMA+. With the decrease of the sorbed water content, the position of the nu2 mode shifts to higher frequency dramatically while the stretching vibration shifts to ...

We demonstrate the site-directed incorporation of an IR-active amino acid, p-azido-L-phenylalanine (azidoF, 1), into the G protein-coupled receptor rhodopsin using amber codon suppression technology. The antisymmetric stretch vibration of the azido group absorbs at approximately 2,100 cm(-1) in a clear spectral window and is sensitive to its electrostatic environment. We used FTIR difference sp...
