Article Abstract:
The Lawrence Berkeley National Laboratory has developed a food sampling procedure that helps detect toxic strains of E. coli in processed foods. By placing the lipid polymer polydiacetylene on plastic strips, a sensitive colorimetric test can be adapted to identify which strain contaminates a food sample.
