Before ionizable lipid nanoparticle (LNP) formulations became central to clinically translated RNA therapeutics, nonviral nucleic acid delivery relied largely on cationic liposomes, cationic polymers, and polymer-lipid complexes that condensed anionic DNA or RNA into nanoscale assemblies. These systems established principles that continue to guide RNA nanomedicine, including electrostatic complexation, colloidal assembly, endosomal trafficking, charge-associated toxicity, degradable carrier design, and intracellular cargo release. Over the past decade, the clinical success of mRNA vaccines has consolidated small-molecule ionizable lipid LNPs as a major formulation platform, owing to their ability to combine efficient RNA encapsulation with improved tolerability, manufacturability, and in vivo expression. This Perspective revisits cationic polymer-lipid nanoparticles not as historical precursors to ionizable lipid LNPs, but as a macromolecular materials space that can clarify and extend current RNA delivery design.

Using thermally expandable microspheres, we generate homogeneous foams with precisely tuned bubble volume fractions up to ∼13%, and compare their behavior with non‑mesogenic silicone analogues. We show that microsphere expansion induces a particle‑centered mesogenic interphase, arising from local elastic distortion and preferential alignment of mesogenic units at the inclusion surface. At low bubble volume fractions (≈0.5%–5%), isolated interphases produce a pronounced enhancement of intrinsic viscoelastic loss. Under impact loading, the optimum shifts to moderate bubble fractions because transient compression also engages bubble deformation, pad compliance, and structural integrity. At higher loadings, interphase overlap and mechanical constraint suppress this effect, and the dissipation returns toward baseline elastomeric values. Large‑strain tensile tests and impact experiments exhibit the same non‑monotonic trend, demonstrating that low‑density LCE foams achieve the highest mechanical energy absorption per unit mass.

In contrast, non-apoptotic programmed cell death (PCD) pathways (ferroptosis, pyroptosis, necroptosis, and cuproptosis) offer high immunogenicity and the ability to bypass resistance mechanisms, yet their clinical application is limited by poor tumor specificity, off-target toxicity, and delivery inefficiency.
