  • Nucleic-acid-responsive gel, method for producing same, and use of same
    Patent number: 8937171
    Abstract: The present invention provides a nucleic-acid-responsive gel which allows (i) a larger volumetric change through structural design, (ii) adjustment of its recognition ability to recognize a nucleic acid, (iii) improvement of sensitivity, and (iv) flexible design according to, e.g., a sequence of target DNA. The nucleic-acid-responsive gel includes a probe formed of two single-stranded nucleic acids which are hybridized with each other. The probe is fixed within a network structure of a polymer gel. The two single-stranded nucleic acids are bound reversibly with each other.
