Reagent Impregnated Swipe for Chemical Detection

With advances in technology, the detection and identification of harmful substances, such as explosives, narcotics, chemical or biological warfare agents, toxins etc., have become crucial. This need is heightened because of growing concerns about safety and security in various contexts, including airports, defense sections, and other sensitive areas. Traditional detection methods routinely fall short of effectively identifying these substances because of their limited scope and specificity. Currently, many methodologies are unable to comprehensively detect a spectrum of harmful target analytes because these methods are designed to detect a limited variety of substances. Additionally, methods that do not offer the ability for sequential detection can complicate the process further. Performing multiple tests for different types of substances can be time-consuming and ineffective, creating a significant gap in the field of substance detection.

Technology Description

The technology is a specialized swipe crafted for detecting target analytes, molecules that can signify the presence of explosives, narcotics, chemical or biological warfare agents, or toxins. The swipe has an associated ionization reagent, which is preferably a low-volatility compound capable of forming ionization reagent-analyte complexes with target analytes. In a unique feature, it can include multiple ionization reagents having different volatilities, making them releasable sequentially during a heating process. Some implementations of the swipe have spatially separated ionization reagents, allowing their sequential release. This technology differentiates itself with its innovative approach toward the sequential release of multiple ionization reagents. By leveraging the volatility characteristics of these reagents, it offers a unique and effective methodology to detect a variety of target analytes. In accompaniment with the spatially segregated option, this swipe widens the horizon of possibilities in detecting multiple target analytes, making it vastly superior to traditional detection swipes.
