Abstract
Abstract Attaching DNA to nanomaterials is the basis for DNA‐directed assembly, sensing, and drug delivery using such hybrid materials. Poly‐cytosine (poly‐C) DNA is a high affinity ligand for four types of commonly used nanomaterials, including nanocarbons (graphene oxide and single‐walled carbon nanotubes), transition metal dichalcogenides (MoS 2 and WS 2 ), metal oxides (Fe 3 O 4 and ZnO), and metal nanoparticles (Au and Ag). Compared to other homo‐DNA sequences, poly‐C DNA has the highest affinity for the first three types of materials. Using a diblock DNA containing a poly‐C block to attach to surfaces, the target DNA was successfully hybridized to the other block on graphene oxide more efficiently than that containing a typical poly‐A block, especially in the presence of non‐specific background DNA, proteins, or surfactants. This work provides a simple solution for functionalizing nanomaterials with non‐modified DNA and offers new insights into DNA biointerfaces.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
