The present invention is concerned with a method of producing a target RNA using a circular DNA, wherein said method does not comprise a step of linearizing said circular DNA. The present invention further relates to a circular DNA comprising an RNA polymerase promoter sequence, followed by a sequence encoding a target RNA, followed by a sequence encoding a self-cleaving ribozyme, followed by an RNA polymerase terminator sequence element, wherein the latter element may comprise several RNA polymerase terminator sequences. Multimeric DNA obtained by rolling circle amplification of said circular DNA is also within the scope of the present invention.

The embodiments disclosed herein utilized RNA targeting effectors to provide a robust CRISPR-based diagnostic with attomolar sensitivity. Embodiments disclosed herein can detect both DNA and RNA with comparable levels of sensitivity and can differentiate targets from non-targets based on single base pair differences. Moreover, the embodiments disclosed herein can be prepared in freeze-dried format for convenient distribution and point-of-care (POC) applications. Such embodiments are useful in multiple scenarios in human health including, for example, viral detection, bacterial strain typing, sensitive genotyping, and detection of disease-associated cell free DNA.
