We reveal the vital role of DNA topology and conformation in directing the combinative self-assembly and condensation pathway and morphology.

diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. thediamondoids family of compounds is one of the best candidates for molecular building blocks (mbbs)in nanotechnology to construct organic nanostructures compared to other mbbs known so far. thechallenge is to find a route for self-assembly of these cage hydrocarbons and their applications in thebottom-up s...

amyloid-β (aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in alzheimer’s disease pathology.uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

Rebuilding injured tissue for regenerative medicine requires technologies to reproduce tissue/biomaterials mimicking the natural morphology. To reconstitute the tissue pattern, current approaches include using scaffolds with specific structure to plate cells, guiding cell spreading, or directly moving cells to desired locations. However, the structural complexity is limited. Also, the artificia...

Control over when and where nanostructures arise is essential for the self-assembly of dynamic or multicomponent devices. We design and construct a DNA origami seed for the control of DAE-E tile DNA nanotube assembly. Seeds greatly accelerate nanotube nucleation and growth because they serve as nanotube nucleation templates. Seeds also control nanotube circumference. Simulations predict nanotub...
