CA: Phage-based bioactive paper a safe Breakthrough for detecting bacterial pathogens in food

Global Food Safety Resource: Bacteriophages (phages) have been deployed as a promising technology to control the growth of various foodborne bacteria since their discovery early in the 20th Century. Lytic phages are viruses—mostly from 20 to 200 nanometres in diameter—that can infect and replicate within bacteria in a strain-specific manner. When a key number of phages accumulate in the cell, they will lyse (dissolve) the bacterial cells. The key to their specificity are the proteins in their tail fibres which recognize receptors on the surfaces of bacterial cell walls.
