Outline of Final Research Achievements

In the present study, we aimed to clarify trinucleotide recognition process occurred inside meso-sized cavities of mesoporous silica. As the results, we found following three characteristics in the trinucleotide recognition: (1) efficient duplex formation of short (3- and 4-mer) DNA fragments could be achieved inside silica mesopores under cryogenic conditions, (2) DNA hairpin structure, on the other hand, was destabilized by the confinement inside the mesopores, (3) the duplex stability was significantly enhanced by size-matching between the pore size and the duplex width.
