Automated Minilab for Antibiotic Testing in Milk
June 8, 2010 | Terry Sharrer
Antibiotic residues in milk present two risks-sick cows, and a source of antibiotic resistance for milk drinkers. Testing milk for these residues is time consuming and costly, but recently researchers at the Technical University of Munich, Germany, developed a microarray device that has dots of 14 different antibiotics positioned on a glass slide with a luminescent material within each dot. Antibody binding to the dots and a light intensity meter reveal the presence of antibiotics. The test is done automatically and takes about six minutes. MORE
