Provided herein is a nucleic acid detection system comprising: a CRISPR system comprising an effector protein and one or more guide RNAs designed to bind to corresponding target molecules; an RNA-based masking construct; and optionally, nucleic acid amplification reagents to amplify target RNA molecules in a sample. In another aspect, the embodiments provide a polypeptide detection system comprising: a CRISPR system comprising an effector protein and one or more guide RNAs designed to bind a trigger RNA, an RNA-based masking construct; and one or more detection aptamers comprising a masked RNA polymerase promoter binding site or a masked primer binding site. In some embodiments, the system may be used to detect viruses in samples. |
