In this study, the feasibility of using copper oxide (CuO) as an interface for the coupling of liquid chromatography (LC) and Fourier-transform infrared (FTIR) spectroscopy was investigated. CuO exhibits low absorption in the 4000 to 1000 cm-1 FTIR spectral region. In addition, LC-FTIR using CuO as the interface was extended to the analysis of sample mixtures containing benzamide and dioctyl se...

Biopolymer films containing chitosan as antimicrobial agent were obtained. As polymer matrix poly(vinyl alcohol) (PVA) and bacterial cellulose (BC) were used. The films were characterized using FTIR spectroscopy. FTIR spectra of the pure components and of composites films reveal strong interactions between chitosan and PVA and chitosan and bacterial cellulose. These composite films could be use...

bacteriorhodopsin (br) is the light harvesting and photoactive proton pump found in the membrane of a salt marsh bacteria. this protein has significant potential to use in optical computing and memory devices due to unique intrinsic physical properties of photo and bioelectric. all these features make br one of the most promising protein candidates in protein memories. protein memory is a kind ...

Supersaturated aqueous solution of magnesium tetraborate (MgB4Ü7 -ЭНгО), its acidified solu­ tions with azeotropic hydrochloric acid, and its diluted solutions with water have been recorded by differential FTIR spectra. The differential FTIR spectra of borate in solutions axe obtained by sub­ tracting FTIR spectrum of water from that of the magnesium borate aqueous solutions. The results showed...

Biosynthesis of silver nanoparticles using Westiellopsis sp. (A15), a filamentous cyanobacterium belonging to the family Fischerellaceae, has been demonstrated. Aqueous silver ions (Ag(+)) when exposed to the culture filtrate of Westiellopsis were reduced in the solution, which were characterized by biophysical measures utilizing the UV-Vis spectroscopy, scanning electron microscopy (SEM), and ...

Fourier Transform Infra Red (FTIR) Spectroscopy is a non-invasive, reagent free diagnostic tool in the analysis of biological fluids. The results can be best employed in the qualitative and quantitative investigation of biological fluids. Multiple myeloma is a disorder in which malignant plasma cells accumulate in bone marrow and produce excess immunoglobulin that leads to many complications. T...
