The technique of Immobilizing DNA in extended nano-space (10-1000 nm) was developed. This technique can be used for rolling circle amplification (RCA) and will finally make single DNA detection and nano-immunoassay possible. Here, we combine UV-mediated immobilization to DNA, examine two different methods for immobilization, and couple to padlock probe and RCA. Detection of fluorescence labeled DNA hybridization to RCA demonstrated that DNA analysis in minute volumes succeeded. Our technique can be served to detect single DNA, and we are developing this technique in extended nano-sapce to define the mechnisms of DNA amplification by record RCA in real time.
