Forming nano‐assemblies is essential for delivering DNA conjugates into cells, with the DNA density in the nano‐assembly playing an important role in determining the uptake efficiency. In this study, we developed a strategy for the facile synthesis of DNA strands bearing perfluoroalkyl (RF) groups (RF‐DNA conjugates) and investigated how they affect cellular uptake. An RF‐DNA conjugate bearing a long RF group at the DNA terminus forms a nano‐assembly with a high DNA density, which results in greatly enhanced cellular uptake. The uptake mechanism is mediated by clathrin‐dependent endocytosis. The use of RF groups to densely assemble negatively charged DNA is a useful strategy for designing drug delivery carriers.

Abstract

Nanocapsules that collapse in response to guanosine triphosphate (GTP) have the potential as drug carriers for efficiently curing diseases caused by cancer and RNA viruses because GTP is present at high levels in such diseased cells and tissues. However, known GTP-responsive carriers also respond to adenosine triphosphate (ATP), which is abundant in normal cells as well. Here, we report the elaborate reconstitution of microtubule into a nanocapsule that selectively responds to GTP. When the tubulin monomer from microtubule is incubated at 37 °C with a mixture of GTP (17 mol%) and nonhydrolysable GTP* (83 mol%), a tubulin nanosheet forms. Upon addition of photoreactive molecular glue to the resulting dispersion, the nanosheet is transformed into a nanocapsule. Cell death results when a doxorubicin-containing nanocapsule, after photochemically crosslinked for properly stabilizing its shell, is taken up into cancer cells that overexpress GTP.
