An Analytical Study of Gallstones by Fourier Transform Infra-Red (FTIR) Spectroscopy Technique

Abstract

Background: Gallstones are a common health issue, especially in individuals with metabolic or dietary disorders. Understanding the composition of gallstones is crucial for both diagnosis and treatment. Fourier Transform Infra-Red (FTIR) spectroscopy provides a powerful method for identifying and characterizing the biochemical components of gallstones. This study aims to analyze gallstones using FTIR spectroscopy to gain insights into their chemical composition.

Methods: Gallstones were collected from 100 patients undergoing cholecystectomy, and FTIR spectroscopy was employed to analyze the samples. Spectra were obtained in the mid-infrared region (4000–400 cm⁻¹), and data were processed to identify key absorption peaks corresponding to different chemical compounds within the stones.

Results: The FTIR spectra of gallstones revealed characteristic peaks indicating the presence of cholesterol, calcium bilirubinate, and other organic and inorganic compounds. The spectral analysis showed that cholesterol was the predominant component in most stones, followed by calcium bilirubinate in mixed stones.

Conclusion: FTIR spectroscopy is an effective, non-invasive method for the identification of the biochemical composition of gallstones. The findings from this study can assist in understanding the formation mechanisms of gallstones and improve clinical treatment strategies.
