Abstract

Chemical spot tests are one of the oldest and simplest presumptive methods of analytical chemistry. They are an integral part of the schematic analysis of different types of substances in various pure and applied scientific disciplines including forensic science. The role of spot tests has remained eternal utility in different branches of forensic science to analyze various types of physical or trace evidences. Forensic experts need to have an absolute understanding of the foundation and technicality behind complex reactions of customary spot tests. Forensic science literature dwells in the diversity of spot tests but an informative and comprehensive compendium of such prose remains occasional and limited in general. Keeping in view the ample history and legacy of spot test, the current review was constructed from a core of historical literature to recapitulate trending applications, chemistry, and limitations of notable “Griess test”, “Luminol test”, “Kastle-Meyer test”, “Phenolphthalein test”, “Ninhydrin test”, and “Spy dust” in forensic science. The aim of this review article was to describe the outlook and likely impact of these tests on the expansion of scientific investigation. The anticipated output of this review is supposed to impart compatible knowledge in the attentive readers interested in understanding legacy and technical details of selected spot tests used in solving crime.

摘要

化学点测试是分析化学中最古老和最简单的推定方法之一。它们是各种纯科学和应用科学学科（包括法医学）中不同类型物质的示意图分析的组成部分。在法医学的不同分支中，现场测试的作用一直是永恒的，用于分析各种类型的物理或痕迹证据。法医专家需要对常规现场测试的复杂反应背后的基础和技术有绝对的了解。法医科学文献存在于现场测试的多样性中，但此类散文的内容丰富且全面的纲要仍然是偶然的且总体上是有限的。考虑到现场测试的丰富历史和遗产，当前的评论是从历史文献的核心构建的，概括了著名的“Griess 测试”、“Luminol 测试”、“Kastle-Meyer 测试”、“酚酞测试”、“茚三酮测试”的趋势应用、化学和局限性，以及法医学中的“间谍尘埃”。这篇评论文章的目的是描述这些测试对扩大科学研究的前景和可能的影响。这篇评论的预期输出应该向有兴趣了解用于解决犯罪的选定现场测试的遗留和技术细节的细心读者传授兼容的知识。这篇评论文章的目的是描述这些测试对扩大科学研究的前景和可能的影响。这篇评论的预期输出应该向有兴趣了解用于解决犯罪的选定现场测试的遗留和技术细节的细心读者传授兼容的知识。这篇评论文章的目的是描述这些测试对扩大科学研究的前景和可能的影响。这篇评论的预期输出应该向有兴趣了解用于解决犯罪的选定现场测试的遗留和技术细节的细心读者传授兼容的知识。
