Abstract:While many dye binding aptamers have been reported, most of them were for light‐up aptamers that can significantly enhance the quantum yield of fluorophores. Sulforhodamine B (SRhB) was used as a target previously to select both DNA and RNA aptamers, and the DNA aptamer was a G‐quadruplex that can bind to a number of rhodamine analogs. In addition, the previous selections were performed by immobilizing the target molecules. In this work, we used the library immobilization method to respectively select aptamers… Show more
