Richard Langlois,a biologist is developing a device that can detect any 100 different pathogens in an hour,before anyone gets sick. the system works by sucking in an air sample,analyzing an air sample,analyzing its components,then putting out a report at fixed intervals.it is basically a flow cytometer-or cell sorter-that Langlois invented in 1970s.the device shines laser beams on chromosomes within cells to make a quick genetic ID.A spin -off of early research into mapping the human genome,the cell sorter is now a standard tool for diagnosing AIDS. using this technology for sniffing bio-terrorism can be real useful. "post sept.11 scenario encourages me to work hard"as said to time magazine in an interview by Langlois. bye!.
