Explosives, chemical agents and drugs can be detected using artificial olfaction.

GOSPEL focusses on three primary areas of AO research for the security market:

• Molecular imprinted polymers (MIPS) - GOSPEL partners are using low-cost components to develop robust miniaturised MIPs which will survive long periods of continuous operation with selectivity for different substances
• Sampling platforms coupled with multiple sensors for trace level detection of explosives and harmful agents
• Miniaturised ion mobility spectrometry - using laser excitation of target gases to enhance selectivity
