Abstract
Ionizable cationic lipids are a critical component of lipid nanoparticles (LNPs), enabling the clinical success of nucleic acid therapeutics through effective encapsulation, delivery, and release. As the field accelerates beyond first-generation RNA medicines, the rational design of next-generation ionizable lipids has become a key area of research. In this review, we outline key design principles that guide the development of efficacious and safe ionizable lipids for nucleic acid delivery. We highlight emerging structural motifs and discuss how these features contribute to improved potency, tolerability, and endosomal escape. Representative lipid structures are used to illustrate these trends. In addition, we describe promising lipids that deviate from heuristic design principles, offering insights into alternative strategies to expand the chemical space. Together, this review provides a framework for the rational development of next-generation ionizable lipids for genetic medicines.

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
