Nanocircles
Nanocircles are small circular single-stranded DNA that can be transcribed by phage and bacterial RNA polymerases. These plasmid-like structures were originally developed by Eric T. Kool's lab. The new technology uses a method called rolling circle transcription (RCT) to encode hammerhead, hairpin and hepatitis delta ribozymes.
