WebBNAs are a recently developed class of artificial nucleic acid analogs with high affinity to ssRNA, DNA, dsDNA. They contain a five-membered or six-membered bridged structure with a "fixed" C3'-endo sugar puckering. This bridge binds to the 2', 4'-position of the ribose to obtain a 2', 4'-BNA monomer. WebMeanwhile, antibody-functionalized SNAs (FSNAs) with a high density of DNA probes act as a bridge for efficiently amplified target-to-DNA signal conversion, which allows the use of DNA-based rolling circle amplification (RCA) as the fluorescence signal amplification technique to quantify non-nucleic acid targets.
