Abstract: Sequence specific DNA-responsive gels were prepared by molecular imprinting using single strand DNA as ligands, which are complementary to target DNA. The DNA-imprinted gel shrank more remarkably in the presence of the target DNA than the nonimprinted gel, but the PAAm gel did not change. The DNA-responsive shrinking of the DNA-imprinted gel is attributed to hybridization between target DNA and DNA ligands. Moreover, the presence of only fullmatch target DNA induced shrinking of the DNA-imprinted gel, but that of one base mismatch DNAs did not Therefore, the DNA-imprinted gels have many potential applications as smart materials for constructing DNArecognition systems
