Bacteria as a Cancer Biosensor
October 24, 2023 | Terry Sharrer
“A new kind of biosensor has been created by an international team of researchers; they made bacteria that are able to detect tumor DNA in another organism. Although bacteria have been modified and used for diagnosing various things before, this is the first time bacteria that recognize specific sequences of DNA have been developed and used outside of cells. This technology was tested in a mouse model of colon cancer, and it could open up new diagnostic approaches for infectious diseases and other disorders. The technique, which has been called cellular assay for targeted CRISPR-discriminated horizontal gene transfer (CATCH), has been reported in Science.” MORE WITH VIDEO
