Progress Toward Absorption, Distribution, Metabolism, Elimination, and Toxicity of DNA Nanostructures
Bibliographic record
Abstract
Abstract DNA nanostructures are perfectly defined nanomaterials, and their shape/structure/surface chemistry (e.g., appended ligands) can be conveniently modulated by designing the sequence of their constituent DNA strands. No other natural or synthetic drug delivery system offers such predictability or modularity. As such, DNA nanostructures may provide exciting and potentially new opportunities for delivering drugs to diseased cell populations, or to specific sub‐cellular compartments. To date, however, most studies have been performed in cell culture and only recently has the field advanced to in vivo testing. Considering how rapidly the field is evolving, this Progress Report surveys available studies involving the testing of DNA nanostructures in vivo, in an effort to elucidate trends and provide guidelines for future developments. This contribution presents the current progress toward characterizing the absorption, distribution, metabolism, elimination, and toxicity of DNA nanostructures.

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.
