<p>For a method of detecting biological weapon use the disclosure suggests to apply known technology relating to interfacial films; a monolayer-forming substances having molecules that when spread at an air /water interface will immerse into the water a hydrophilic terminal group for each molecule, with a long-chain carbon-containing hydrophobic group extending vertically upward away from the water. Such monolayers manifest monitorable properties which are susceptible using known instrumentation means to measurement of changes induced by biological contaminants, thus making it possible to determine by appropriate testing what a bioattack signature change would be. Given siting of a monolayer coated aqueous body in a reservoir where a biological attack may occur, monitoring the monolayer properties for the signature change can detect whether and when such an attack does occur. One example of enacting the method involves a lake-sized water reservoir coated by a mixed monolayer which changes respecting color absorbance when bacteria and a biocide in the monolayer interact. Another example uses an instrumented film balance, i.e., Langmuir trough as the reservoir, which is small enough for siting anywhere needed, e.g., inside postal stations or other important buildings.</p> |
