To determine whether DNA can be confined within neutral lipid multilamellar phases without relying on electrostatic interactions.
Investigated ternary mixtures of DNA, neutral lipids, and water using small-angle X-ray scattering across varying lipid-to-DNA weight ratios.
Assessed molecular packing and spatial organization using one-dimensional electron density profiles and correlation peaks.
High lipid-to-DNA weight ratios successfully confined DNA within a neutral multilamellar smectic phase despite lacking electrostatic attraction.
Small-angle X-ray scattering revealed a DNA-DNA correlation peak corresponding to two-dimensional ordering of DNA intercalated between neutral bilayers.
The neutral multilamellar phase dispersed into small multilamellar vesicles capable of encapsulating high quantities of DNA.
