“…The technique also has promising potential for detecting early cancer. Our research group has successfully used FT-IR spectroscopy to diagnose multiple kinds of carcinoma, such as stomach, colon, liver, esophagus, lung, gallbladder, breast, and parotid gland (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24).…”

Background: Fourier transform infrared (FT-IR) spectroscopy is an effective tool for investigation of chemical changes at the molecular level. We previously demonstrated that FT-IR spectroscopy can reliably distinguish multiple types of carcinoma from healthy tissue. Because various stomach diseases are common, it is important to explore a noninvasive and rapid method to detect malignancy and gastritis in endoscopic biopsies. Our aim was to classify endoscopic biopsies into healthy, gastritis, and malignancy through the use of FT-IR spectroscopy. Methods: A total of 103 endoscopic samples, including 19 cases of cancer, 35 cases of chronic atrophic gastritis, 29 cases of chronic superficial gastritis, and 20 healthy tissue samples, were obtained at the First Hospital of Xi'an Jiaotong University, China. A modified attenuated total reflectance accessory was linked to a WQD-500 FT-IR spectrometer for biopsy measurement. The spectral characteristics for different types of tissues were correlated with the corresponding pathology results. The gastric biopsies were classified by FT-IR spectroscopy and a discriminant analysis method. Results: There were significant differences in the FT-IR spectra of four types of gastric biopsies. The discriminant analysis results demonstrated that the sensitivity of FT-IR detection for healthy, superficial gastritis, atrophic gastritis, and gastric cancer was 90%, 90%, 66%,

“…FTIR spectroscopy is used for both qualitative [17][18][19][20][21] and quantitative [22][23][24][25][26][27][28][29][30][31][32] analysis. By thorough literature survey, we could not find any report based on the FTIR based kinetics of effect of nano-sized material on the structure-property relationship of PANI.…”

This paper explains the synthesis and characterizations of Poly(aniline) (PANI)/Sb 2 O 3 nano composite by in-situ polymerization method. It was indicated that Sb 2 O 3 itself could catalyze the oxidative polymerization of aniline through its active surface effect. This could be due to the intercalation of PANI chains into the basal spacing of Sb 2 O 3 . TGA counseled the thermal stability of PANI. Through FTIR study, the structure of PANI was confirmed. Comparison of polymerized aniline composite with two different initiators was done. HRTEM confirmed the nano size of Sb 2 O 3 . The intercalating nature of PANI chains into the basal spacing of Sb 2 O 3 was also tested.
