Analysis of the Ex-vivo transformation of Semen, Saliva and Urine as they dry out using ATR-FTIR spectroscopy and chemometric Approach

Abstract: The ex-vivo biochemical changes of different body fluids are potential marker for the estimation of TSD. Infrared spectroscopy has great potential to reveal the biochemical changes in these fluids as previously reported by several researchers. Present study is focused to analyze the spectral changes in the ATR-FTIR spectra of three body fluids, commonly encountered in violent crimes i.e., Semen, Saliva and Urine as they dry out. The whole analytical timeline is divided into relatively slow phase I due to major… Show more

“…It has been understood through the researches that fluorescence could be detected on the older stains on fabrics to a comparatively greater extent than the fresh stains [3]. There are a number of studies that have been carried out to understand the effect of ageing of seminal stains on the spectroscopic analysis [4][5][6][7][8]. where other detailed information can also be obtained in one single measurement.…”
