Abstract© 2020, Springer Science+Business Media, LLC, part of Springer Nature. Purpose: Doxorubicin (Dox) being a hydrophobic drug needs a unique carrier for the effective encapsulation with uniformity in the aqueous dispersion, cell culture media and the biological-fluids that may efficiently target its release at the tumor site. Methods: Circular DNA-nanotechnology was employed to synthesize DNA Nano-threads (DNA-NTs) by polymerization of triangular DNA-tiles. It involved circularizing a linear single-stranded scaffold strand to make sturdier and rigid triangles. DNA-NTs were characterized by the AFM and Native-PAGE tests. Dox binding and loading to the Neuregulin1 (NRG1) functionalized DNA based nano-threads (NF-DBNs) was estimated by the UV-shift analysis. The biocompatibility of the blank NRG-1/DNA-NTs and enhanced cytotoxicity of the NF-DBNs was assessed by the MTT assay. Cell proliferation/apoptosis was analyzed through the Flow-cytometry experiment. Cell-surface binding and the cell-internalization of the NF-DBNs was captured by the double-photon confocal microscopy (DPCM). Results: The AFM images revealed uniform DNA-NTs with the diameter 30 to 80 nm and length 400 to 800 nm. PAGE native gel was used for the further confirmation of the successful assembly of the strands to synthesize DNA-NTs that gave one sharp band with the decreased electrophoretic mobility down the gel. MTT assay showed that blank DNA-NTs were biocompatible to the cells with less cytotoxicity even at elevated concentrations with most of the cells (94%) remaining alive compared to the dose-dependent enhanced cytotoxicity of NF-DBNs further evidenced by the Flow-cytometry analysis. Conclusion: Uniform and stiffer DNA-NTs for the potential applications in targeted drug delivery was achieved through circular DNA scaffolding.
