Abstract
Herein, we introduce a sequence-specific plasmonic loop-mediated isothermal amplification (LAMP) assay with dual, complementary color readouts enabled by CRISPR Cas12a. Using this assay, any double-stranded LAMP amplicon containing a 5'-TTN PAM sequence can be recognized by Cas12a through a specific CRISPR RNA. The signal transduction is achieved using two orthogonal plasmonic systems mediated by Cas12a.
