DETECTR (IMAGE) University of California - Berkeley Caption The new DETECTR system, created at UC Berkeley based on CRISPR-Cas12a, can analyze cells, blood, saliva, urine and stool to detect genetic mutations, cancer and antibiotic resistance as well as diagnose bacterial and viral infections. It works by amplifying target DNA with the RPA system, and using a fluorescent reporter (F star) tied to single-stranded DNA to signal Cas12a has found its target.
