RNA complexes, methods of their production and sensors and analytical methods involving same

摘要

The invention includes RNA complexes comprising at least three monomeric units of an RNA molecule, each monomeric unit comprising an RNA polymer having first and second helical domains that have respective first and second binding sites, wherein the first binding sites are adapted to binding to one another and are not adapted to bind to the second binding sites, and the second binding sites are adapted to binding to one another and are not adapted to bind to the first binding sites; such that the at least three monomeric units are adapted to self-assemble by forming pairs of cognate interactions and so as to form the RNA complex in a circular closed complex. The invention also includes derivatives of these complexes including aptamers, and analytical methods and devices using same.

1. An RNA molecule comprising RNA having a first double helical domain having a first double-stranded binding site and a second double-stranded binding site, said first double helical domain connected to a second double helical domain having a first loop and a second loop, wherein the first double helical domain and the second double helical domain are each capable of binding the first loop or the second loop and wherein at least one of said double helical domains comprises an aptamer.
