#  You Ponce!

 Written by S Johnson on 18 October 2009.

Jet Propulsion Laboratory (JPL) have developed what they think it a high speed test to deal with biological contamination detection. Adrian Ponce within JPL has used a method using dipicolonic acid as a trigger for a luminescing effect on terbium - terbium is the chemical that generates the colour green on television screens. Once the dipicolnic acid and the terbium connect the colour change can be seen under a UV lamp – this colour change is symptomatic of live endospores. As with anything that does contamination detection (especially bio) if it works it will be truly revolutionary to the industry.
