Fourier Transform Infrared (FTIR) Spectroscopy of Biological Tissues
This article reviews some of the recent advances on FTIR spectroscopy in areas related to natural tissues and cell biology. It is the second review publication resulting from a detailed study on the applications of spectroscopic methods in biological studies and summarizes some of the most widely used peak frequencies and their assignments. The aim of these studies is to prepare a database of m...
متن کاملStudies on the Formation of Mullite from Diphasic Al2O3-SiO2 Gel by Fourier Transform Infrared Spectroscopy
Al2O3-SiO2 diphasic gel was synthesized by sol gel route from aluminium nitrate and silicic acid following aqueous phase colloidal interaction. The precursor gel powder was thoroughly characterized by chemical analysis, measurement of surface area and bulk density measurement. The gel powder was further characterized by thermogravimetry, XRD diffraction stud...
متن کاملCancer grading by Fourier transform infrared spectroscopy.
Thirty-nine freeze-dried tissue samples from 17 lymphoid tumors (nine malignant non-Hodgkin's lymphomas) were studied by Fourier transform infrared (FTIR) spectroscopy. The absorbance ratio A1121/A1020 increased, along with the emergence of an absorbance pulse at 1121 cm-1, with increasing clinicopathological grade of malignant lymphoma. An increasing A1121/A1020 ratio from benign to malignant ...
متن کاملQuality Control of Valerianae Radix by Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) Spectroscopy.
(Acetoxy-)valerenic acid and total essential oil content are important quality attributes of pharmacy grade valerian root (Valerianae radix). Traditional analysis of these quantities is time-consuming and necessitates (harmful) solvents. Here we investigated an application of attenuated total reflection Fourier transform infrared spectroscopy for extractionless analysis of these quality attribu...
متن کاملRapid diagnostic method of tobacco products in saliva by fourier transform infrared spectroscopy (FTIR).
The present study was designed to explore the easy and fast method diagnosis of tobacco products in saliva of tobacco users (TU) by FTIR. Sixty four male tobacco users (TU) with mean age range 15.3 to 30.7 years were randomly selected for collection of saliva samples before and after tobacco use (smoking, chewing and dipping tobacco). Twenty were the smoking tobacco users (STU), 24 were chewing...
