Outline of Final Research Achievements |
DNA-conjugated stimuli-responsive materials coordinate the molecular recognition properties of DNA and actuator properties of thermoresponsive polymer, poly(N-isopropylacrylamide) (pNIPAM). In some specific conditions, DNA-pNIPAM changes its dispersion state in response to whether conjugated DNA is single-stranded (ss) or double-stranded (ds). Under the condition where entropic repulsion controls the aggregation behavior of the conjugate, the aggregation was controlled by whether the dangling end of dsDNA had a specific structure (e.g. G-quadruplex) or not. Then, this property was combined with the molecular recognition of a DNA aptamer. The target protein, thrombin, bound to DNA-pNIPAM, and this binding changed the aggregation behavior of the conjugate.
