Abstract
This paper describes the design and development of a small, portable alarm device that can be used by first responders to an emergency event to warn of the presence of low levels of a toxic nerve gas. The device consists of a rigid reusable portion and a consumable packet that is sensitive to the presence of acetylcholinesterase inhibitors such as the nerve gases Sarin or Soman. The sensitivity level of the alarm is set to be at initial physiological response at the meiosis level, orders of magnitude below lethal concentrations. The AChE enzyme used is specific for nerve-type toxins. A color development reaction is used to demonstrate continued activity of the enzyme over its twelve-hour operational cycle.
