Abstract
Substrate-mediated transfection is one of the key strategies for localized gene delivery. Layer-by-layer (LbL) polyelectrolyte deposition is a promising technique which enables controlled delivery of a number of biofactors, including nucleic acids. Here, we embed lipoplexes containing plasmid DNA within polyelectrolyte multilayers composed of glycol-chitosan (Glyc-CHI) and hyaluronic acid (HA) in order to produce a film system that enables localized, surface-based transfection. The topography and morphology of the resulting multilayers were characterized after lipoplex absorption and during subsequent film build-up via atomic force microscopy (AFM) and scanning electron microscopy (SEM), respectively. DNA embedding efficiency and release were then examined. Lipoplex-containing Glyc-CHI/HA films were found to successfully transfect NIH3T3 fibroblasts and HEK293 kidney cells in vitro, maintaining transfection levels of approximately 20% for a period of at least 7 days.

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
