Abstract
A new series of dissymmetric hemifluorocarbon bolaamphiphiles were designed to investigate their main characteristics as a non-viral gene transfer carrier. The dissymmetric functionalization of diiodoperfluorooctane led to bolaamphiphile molecules composed of a partially fluorocarbon core end-capped with a glycoside and an ammonium salt. The physical–chemical results, cytotoxic effect, gene complexation and transfection efficiency were analyzed and functional relationships were addressed. The study clearly showed that the chemical structure of bolaamphiphiles influences the complexation with DNA, gene transfer, and cytotoxicity. Two different polar head groups (histidine and lysine) have been tested for their efficiency to complex DNA. The impact of the side chain of bolaamphiphile on the interaction with DNA was also investigated. Good transfection activity was demonstrated for partially fluorinated bolaamphiphile having lysine head group. Weak cell cytotoxicity, positive surface charge of bolaplexes, well-defined structure, and protection from the DNAses seem to be essential characteristics for efficient transfection.

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
