In recent years, collection and analysis of condom evidence in sexual assault investigations are becoming more common in forensic caseworks. Condom analysis can provide investigative leads or establish potential contact between the suspect and victim in the absence of DNA evidence or supplement biological evidence. Recent forensic literature shows significant advancements in the analysis of condom lubricants, including casework samples. There is an increasing trend in the use of chemometric tools for the comparison and interpretation of the results. This review highlights the advances in common analytical techniques used for the analysis of condom lubricants with a particular focus on the developments occurring in recent years, including chemometric interpretation. The analysis of reference and casework samples (swab samples, samples on skin, clothing and fingermark) are discussed separately. For casework samples, the transfer and persistence of different lubricant formulations are discussed, along with their detection with various analytical approaches. The issues with the interpretation of lubricants are also discussed in another section, with particular emphasis on samples such as personal hygiene products which have similar formulations with sexual lubricants and the interpretation of negative profiles. The current challenges in the field and prospects for future research are also discussed.
近年来,在法医工作中,收集和分析性侵犯调查中的避孕套证据变得越来越普遍。在没有 DNA 证据或补充生物证据的情况下,避孕套分析可以提供调查线索或确定嫌疑人和受害者之间的潜在接触。最近的法医文献显示,避孕套润滑剂分析取得了重大进展,包括案例样本。使用化学计量学工具进行比较和解释结果的趋势正在增加。本综述重点介绍了用于分析避孕套润滑剂的常用分析技术的进展,特别是近年来的发展,包括化学计量学解释。分别讨论了参考样本和案例样本(拭子样本、皮肤、衣物和指纹上的样本)的分析。对于案例样本,讨论了不同润滑剂配方的转移和持久性,以及各种分析方法对其的检测。还在另一部分讨论了润滑剂解释的问题,特别强调了个人卫生用品等类似配方的性润滑剂和阴性谱的解释。还讨论了该领域当前的挑战和未来研究的前景。
