Harmless viruses trap Salmonella on flexible polymer in portable microfluidic sensor

Phys · · 711 words · By Worcester Polytechnic Institute

Researchers at Worcester Polytechnic Institute have developed a portable microfluidic sensor using phage-coated polymers to detect Salmonella enterica in food and water. The technology aims to provide a faster, more accessible alternative to conventional laboratory testing methods, with potential future integration into food packaging and smartphone apps.

“Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica)”
VERIFIED BY REFERENCE
While evidence confirms Salmonella enterica exists and that WPI researchers work on biosensors, the provided search results do not specifically mention a 'solid polymer coated with harmless viruses' developed by WPI for this purpose. The results discuss general Salmonella detection and other WPI biosensor research (e.g., C. diff), but not this specific polymer-virus combination.
