Abstract
A sensor for sensing pathogens includes a molecularly imprinted polymer membrane applied to a surface of a flexible backing. The molecularly imprinted polymer membrane is capable of selectively binding pathogens such that binding sites will be fluorescent in the absence of pathogens and fluorescence is quenched in the presence of pathogens. Monitoring the fluorescence quenching will provide detection of contamination.

A sensor for sensing food pathogens, said sensor comprising a molecularly imprinted polymer membrane imprinted with one or more binding sites that are capable of selectively binding pathogens such that binding sites will be fluorescent in the absence of pathogens and fluorescence is quenched in the presence of pathogens.
A sensor for sensing food pathogens, said sensor comprising:
- a flexible backing;
- and
- a molecularly imprinted polymer membrane applied to a surface of said flexible backing, said molecularly imprinted polymer membrane being imprinted with one or more binding sites that are capable of selectively binding pathogens such that binding sites will be fluorescent in the absence of pathogens and fluorescence is quenched in the presence of pathogens.
A system for sensing food pathogens, said system comprising:
- a molecularly imprinted polymer membrane imprinted with one or more binding sites that are capable of selectively binding pathogens such that binding sites will be fluorescent in the absence of pathogens and fluorescence is quenched in the presence of pathogens;
- and
- a fluorescence scanner for scanning said molecularly imprinted polymer membrane to detect patterns and magnitudes of fluorescence quenching.
