A part of the group’s work was devising a technique to ship airborne virus particles to the sensor.
With chook flu, says Rajan Chakrabarty, a professor of power, environmental, and chemical engineering at Washington College and lead writer of the paper, “the dangerous apple is surrounded by one million or a billion good apples.” He provides, “The problem was to take an airborne pathogen and get it right into a liquid type to pattern.”
The crew achieved this by designing a microwave-measurement field that sucks in giant volumes of air and spins it in a cyclone-like movement in order that particles follow liquid-coated partitions. The method seamlessly produces a liquid drip that’s pumped to the extremely delicate biosensor.
