A preliminary investigation of transfer of condom lubricants in the vaginal matrix

Innovative Vibrational Spectroscopy Research for Forensic Application

“…Therefore, Saric et al conducted a preliminary investigation into the transfer of condom lubricants in the vaginal matrix using DRIFTS. 109 Samples were extracted from the vaginal swab using hexane, and KBr pellets were prepared from the extracts for analysis. They were able to identify and differentiate between silicone and nonsilicone residues.…”

“…Traces of condom lubricants are recovered from vaginal swabs, and it can be difficult to isolate or identify the presence of the residue within a complex matrix. Therefore, Saric et al conducted a preliminary investigation into the transfer of condom lubricants in the vaginal matrix using DRIFTS . Samples were extracted from the vaginal swab using hexane, and KBr pellets were prepared from the extracts for analysis.…”

On the Identification of Body Fluids and Tissues: A Crucial Link in the Investigation and Solution of Crime

“…To address the question of primary deposition or secondary transfer, TPPR (transfer, prevalence, persistence and recovery) issues are studied [21][22][23][24][25][26][27][28][29][30][31]. The aspect of transfer The 'findings' in the case can relate to cellular material matching victim or suspect which under H1 is indicative of an offensive activity (e.g., blood matching the victim on the blade of a knife indicative of the victim being stabbed; cellular material matching the suspect on the handle of a knife supporting the proposition that the suspect carried out the stabbing).…”

“…To address the question of primary deposition or secondary transfer, TPPR (transfer, prevalence, persistence and recovery) issues are studied [21][22][23][24][25][26][27][28][29][30][31]. The aspect of transfer appears the most complex among TPPR issues and many studies have gained information on transfer rates, and the various aspects that influence transfer rates such as wet or dried state, application of friction and pressure, smooth or rough surface and size of the stain [32][33][34][35][36][37][38].…”

Negative results: Investigations into the quantification of silicone-based condom lubricants in solution by DRIFTS-FTIR

“…It is therefore feasible that DRIFTS could be used for the quantification of silicones, enabling development of transfer and persistence models. A valid quantification method using DRIFTS-FTIR would be of significant interest in a forensic interpretation view: as formerly illustrated by and [26,27] who were investigated transfer and persistence of silicone-based lubricants in sexual intercourses, the obtention of accurate quantification for transfer and persistence studies would enable to enhance the quality of the models built and investigate further the mechanisms involved in both transfer and persistence.…”
