Here is an article just published in Physics World -Holograms that respond to physical, chemical and biological stimuli There is a lot of research going on out there, hope Ramp really gets going soon. ~~ Dick Researchers have used similar holographic sensors to monitor the depletion of glucose during the growth of the spore-forming organism Bacillus subtilis — a close relative of Bacillus anthracis, which causes anthrax and is thus a potential biological weapon. In this case, holograms offer considerable advantages over conventional enzyme-based sensors that use straight forward biochemical reactions because they do not consume glucose and therefore do not reduce substrate levels in small-volume samples, which could give an inaccurate result. We are now assessing the potential of such a sensor as a rapid anthrax-identification system for use by the emergency services following a terrorist incident.
