This document provides a literature review of colorimetric indicators for nerve-agent detection, offering valuable insights into the development and use of these indicators. By reading this document, readers can gain a deeper understanding of the potential applications and benefits of colorimetric indicators in detecting nerve agents. Given the current public concerns regarding chemical warfare and the need for effective detection methods, this document offers relevant and timely information for researchers, policymakers, and security agencies. This document is a literature review of colorimetric indicators for nerve-agent detection. It provides an introduction to the topic and discusses various colorimetric indicators and their mechanisms of action. The document highlights the use of two-step processes to reduce the possibility of false-positive results and improve selectivity. It also mentions the testing of different organophosphorus compounds and the development of test strips embedded with colorimetric indicators. Overall, the document emphasizes the potential of colorimetric indicators as a low-cost and rapid screening method for detecting nerve agents. This annotated edition illustrates the capabilities of the AI Lab for Book-Lovers to add context and ease-of-use to manuscripts. It includes several types of abstracts, building from simplest to more complex: TLDR (one word), ELI5, TLDR (vanilla), Scientific Style, and Action Items; essays to increase viewpoint diversity, such as Grounds for Dissent, Red Team Critique, and MAGA Perspective; and Notable Passages and Nutshell Summaries for each page. This document was chosen for publication during a periodic review of new publications released by the National Technical Research Laboratory (NTRL). On a personal note, this document struck a chord because my grandfather and namesake, William Zimmerman III, was a chemist who shared a patent for a colorimetric temperature indicator.
