The present invention relates to a molecule delivery technology and a carrier technology, which may selectively deliver a material to a desired specific cell and living tissue. The present invention may be utilized in the field of a drug carrier which effectively delivers an imaging probe and a therapeutic agent to an affected part.

Drug carrier having self-assembled 3-D nucleic acid nanostructure

Provided are a self-assembled polyribonucleotide-protein complex including a polyribonucleotide including a plurality of first repeating units having a single guide RNA (sgRNA) region and a small interfering RNA (siRNA) region; and one or more nuclease proteins binding to the sgRNA region, and use thereof.

Self-assembled ribonucleoprotein nanoparticles

Provided is a method of preparing nanoparticle-type polynucleotides, the method comprising forming the polynucleotides comprising modified nucleotides, in which the forming includes chemically synthesizing the polynucleotides comprising modified nucleotides, synthesizing the polynucleotides comprising modified nucleotides using an enzyme, or a combination thereof.

Method of packing polynucleotides

The present invention relates to contrast medium composition and a method of bio imagination using the same. The contrast medium composition of the present invention includes a biomolecule, DNA nanostructure, as an active ingredient, is fundamentally non-cytotoxic and non-immunogenic and is not likely to induce safety problems that may be observed in other organic or inorganic contrast medium composition. In addition, the contrast medium composition of the present invention not only facilitates diagnosis of disease through sufficient contrast enhancement effect by showing excellent cellular uptake and intracellular stability and can visualize even SLNs which is difficult to be visualized traditionally, so can judge metastasis of cancer easily and apply lower invasive treatment.
