New MOF enables rapid nerve agent detection

Researchers have developed a new method for detecting nerve agents using a specially engineered metal-organic framework (MOF). This approach improves on existing detection methods by offering rapid and reliable results, addressing limitations like environmental interference. The new MOF, called MOF-525, features a high defect density that enhances its ability to selectively identify phosphonyl fluoride nerve agents. It produces a distinct red fluorescence signal when these agents are present, allowing for quick detection. This method shows high sensitivity and a rapid response time of less than one second. It also remains effective in challenging conditions, such as acidic environments and humidity, marking a significant advancement in nerve agent detection technology.
