Due to the escalation of international military tensions, chemical warfare agents (CWAs) are once again becoming a major threat. Rapid detection of their presence in air or water, even in extremely low concentrations, is an essential part of safety precautions. Detection tubes (DTs) are a commonly used type of chemosensor and the development of their innovative second-generation involves the search for suitable highly porous carriers with a high specific surface area. Such carriers should more effectively adsorb detection reagents and CWAs, which should lead to an overall improvement in sensitivity and detection rate.
