Guest-Mediated Access to a Single DNA Nanostructure from a Library of Multiple Assemblies
Bibliographic record
Abstract
We present a method in which a small molecule template is used to access a single DNA nanostructure from a library of multiple assemblies. DNA building blocks 2 and 2 ‘, in which two identical DNA arms branch from a fully rigid organic vertex, were synthesized and their self-assembly was found to generate a small dynamic library of products. The small molecule Ru(bpy) 3 2+ was found to provide access to a single member from this library (i.e., square 5 ) and was also found to re-equilibrate each other already formed member into 5 quantitatively. The use of a small molecule to access a single DNA assembly from many possible combinations introduces an additional level of control in DNA construction. In addition, the ability of this template to transform the other members into the same single product provides a built-in correction mechanism that helps ensure the integrity of the construction process, even when “errors” are made. We apply this approach to predictably generate periodic 1D DNA fibers extending over tens of microns, using two trifunctional symmetrical DNA building blocks that otherwise assemble into ill-defined oligomeric networks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
