Biosensors: The New Must-Have Kitchen Accessory


In a world where it’s no longer safe to eat spinach, there just may be a market for microbe-detecting gizmos that can be used in your own kitchen.

Today we learned from an L.A. Times article that researchers are already working to build biosensors that can detect baleful bacteria such as E. coli O157:H7, salmonella, or Listeria monocytogenes, which grows on cheese and lunchmeats.

A handy tool, no doubt. But I’m still waiting for a way, other than sniffing the carton, to tell if the milk has gone bad.
