Abstract

Fingerprints have two fundamental characteristics that allow human identification in an unequivocal way, uniqueness, and immutability. Due to these characteristics, they have been used as a tool in the criminal sphere, producing elements that indicate the presence of one or more suspects at a crime scene. Latent fingerprints are invisible to the naked eye and require prior treatment to be developed. Latent fingerprint developers are important because they react with the organic or inorganic secretions in the fingertips by chemical reactions or intermolecular interactions, such as hydrogen bonds and Van Der Waals forces. Thus, this review approaches the historical-scientific evolution of fingerprint expertise, the fingerprint formation process, and its classification according to Juan Vucetich, the first to use fingerprints to individualize prisoners. The three main fingerprint development techniques (powder, ninhydrin, and cyanoacrylate technique) were also discussed, as well as new perspectives for the use of natural substances as latent fingerprint developers (Seaweed, Spice, and Chalcones), which contain low levels of toxicity and socio-environmental sustainability. Finally, the advancement in the use of mass spectrometry to study fingerprint residues is highlighted, thus bringing additional information about the individual, such as the use of drugs of abuse, condom lubricants, and medications, as well as information about the composition chemistry of the LFP, enabling a new perspective in the investigation of the crime scene.

潜在指纹的研究综述

指纹有两个基本特征，即唯一性和不变性，使人类能够明确地进行识别。由于这些特点，它们被用作犯罪领域的工具，产生表明犯罪现场有一个或多个嫌疑人的元素。潜在的指纹是肉眼看不见的，需要事先处理才能显影。潜在指纹显影剂很重要，因为它们通过化学反应或分子间相互作用(如氢键和范德华力)与指尖中的有机或无机分泌物发生反应。因此，本文回顾了指纹技术的历史科学演变，指纹形成过程，并根据胡安·武切奇(Juan Vucetich)的分类，他是第一个使用指纹来个性化囚犯的人。讨论了三种主要的指纹显影技术(粉末、茚三酮和氰基丙烯酸酯技术)，以及利用天然物质(海藻、香料和查尔酮)作为潜在指纹显影剂的新前景，这些物质具有低水平的毒性和社会环境可持续性。最后，强调了使用质谱法研究指纹残留物的进展，从而提供了关于个人的额外信息，例如滥用药物，避孕套润滑剂和药物的使用情况，以及关于LFP组成化学的信息，从而为犯罪现场的调查提供了新的视角。

期刊介绍： Forensic Chemistry publishes high quality manuscripts focusing on the theory, research and application of any chemical science to forensic analysis. The scope of the journal includes fundamental advancements that result in a better understanding of the evidentiary significance derived from the physical and chemical analysis of materials. The scope of Forensic Chemistry will also include the application and or development of any molecular and atomic spectrochemical technique, electrochemical techniques, sensors, surface characterization techniques, mass spectrometry, nuclear magnetic resonance, chemometrics and statistics, and separation sciences (e.g. chromatography) that provide insight into the forensic analysis of materials. Evidential topics of interest to the journal include, but are not limited to, fingerprint analysis, drug analysis, ignitable liquid residue analysis, explosives detection and analysis, the characterization and comparison of trace evidence (glass, fibers, paints and polymers, tapes, soils and other materials), ink and paper analysis, gunshot residue analysis, synthetic pathways for drugs, toxicology and the analysis and chemistry associated with the components of fingermarks. The journal is particularly interested in receiving manuscripts that report advances in the forensic interpretation of chemical evidence. Technology Readiness Level: When submitting an article to Forensic Chemistry, all authors will be asked to self-assign a Technology Readiness Level (TRL) to their article. The purpose of the TRL system is to help readers understand the level of maturity of an idea or method, to help track the evolution of readiness of a given technique or method, and to help filter published articles by the expected ease of implementation in an operation setting within a crime lab.
