New tech to make milk safer

Researchers at Concordia University in Montreal, Quebec, Canada have developed a new, high-tech device capable of detecting harmful foreign substances in milk and other foodstuffs, the university announced.
Concordia mechanical and industrial engineer Muthukumaran Packirisamy and his colleagues developed and perfected the microfluidic biosensing technology over two years, with support from Valeo Management, a partnership that develops prototypes from university research, and Quebec's Ministère du Développement Économique, de l'Innovation et de l'Exportation (MDEIE), according to Concordia's announcement.
About the purpose of his team's mirofluidics project, Packirisamy explained,
"Even though Canada does not allow the use of growth hormones and excessive antibiotics in cows, until now there were no methods or equipment to effectively measure residual traces in milk."
Concordia's microfluidic biosensor could be used commercially to detect bovine growth hormones in milk and other dairy products soon, according to the researchers.

The Concordia team's microfluidic biosensing device was presented to potential industry partners in Boston recently, including representatives from NASA who were interested in its potential to detect bacteria and other pathogens and contaminants on future space missions, according to the university's announcement, which did not discuss the specific technology used.
About earlier microfulidic biosensor research by other groups, Physorg.com reported:
Using microfluidic biosensors to test for contaminants in foods would allow more thorough testing because the tiny devices can provide results more quickly, cheaply and accurately than bulkier testing processes (including simple litmus strip testing and sending samples to laboratories for detailed testing), so computer chip minilabs that detect and analyze chemoluminescence (or other sub-millimeter scale chemical reactions) could reduce production costs and losses.
In related news, Digital Journal reported in August about various microfluidic lab-on-a-chip (LOC) technologies being developed for medical diagnostic testing by separate research groups worldwide.
The Wikipedia has listed many active microfluidics research groups by world region and country with brief descriptions of their work, and the peer-reviewed journal Lab on a Chip has published details about many diverse microfluidics studies and projects.
