Pheromone Research

Pheromones are molecular signals animals send each other to indicate sexual state, agression, identity, and other psychological states.  In some ways pheromones are similar to odors but may not be handled by the same physiological mechanisms.  The word pheromone comes from the Greek words Pheran (to  transfer) and Horman (to excite)  Researchers have shown that the human VNO (Vomeronasal organ)  is connected directly to the limbic system, that part of the brain that is responsible for exploration, flight or fight, for identifying with the environment and reacting to it. The limbic system is also responsible for controlling emotional and behavioral patterns. Major histocompatibility complex (MCH) genes are among the most diverse of all genes, constituting, in essence, a genetic signature of the individual. MHC genes help the body to recognize its own healthy cells, to identify invading pathogens and to reject foreign tissues and may transfer signals via pheromones.

Research on Artificial Noses (academic and commercial)

Artificial Noses use a variety of experimental technologies to sense and interpret molecules in the air usually associated with odors.  Typically a device determines a profile of molecules and uses sophisticated analysis algorithms. to match it against pre-stored templates associated with particular odors.  For example,At the California Institute of Technology (Caltech), Nathan Lewis is building on the idea of conductive polymers by adding carbon black (in essence, soot) to the polymer. This provides the necessary variety of response because the task of conducting the electricity is taken over by the carbon black. The resistance of a detector changes as the polymer swells in response to its reaction with the odour molecules and thus alters the connections between the particles of carbon black. The University of Illinois project uses spectroscopic analysis of the gas samples.  Other gas sensors use these technologies: metal oxide, conducting polymer, acoustic wave (bulk and surface), field-effect transisitors, electrochemical, pelistors and fibre-optic.
