The CRISPR diagnostics era is here

ZikaTest_Paper-based-results-002-1024x576Elementary dear Watson, we should have expected that. The CRISPR wave is hitting diagnostics, with a new high sensitivity detection platform named after Arthur Conan Doyle’s popular detective. The acronym SHERLOCK stands for “Specific High Sensitivity Enzymatic Reporter UnLOCKing”. While the technique is used in thousands of labs to turn genes on and off, CRISPR embarks also on epidemiology and learns how to identify nucleic acids from viral and bacterial pathogens to diagnose infections. The paper published in Science by James Collins, Feng Zhang and colleagues heralds a new generation of low cost diagnostic tests with single-base specificity, easy to use even when oubreaks occur in remote areas.
