Massachusetts researchers add nanotransmitters to microfluidic arrays

Researchers have found a new way of detecting dangerous pathogens like anthrax.  In this method they use a microfluidic chip that performs DNA sequencing to rapidly identify bacteria.  This device can be used at airport screenings and other security points.

Researchers have compiled a database of unique DNA base sequence patterns.  These patterns are known as "bar code panels."  DNA is tagged with a  flouresecent tag assigned to the sequence of the suspected substance.  It is then fed through the microfluidic chip where the DNA passes over a beam that labels the fluoresce.  The resulting flashes are recorded and compared to the databases.  


This approach is revolutionizing because it uses waveguide and nanoantennas and this helps researchers detect shorter strands with greater accuracy.  All they need is a couple of DNA particles and they can easily detect dangerous pathogens.
