Adding extra polyethylene glycol spacers between lipid anchors and DNA increases functional DNA availability and improves light-directed DNA-printing of cells (LD-DPC), despite anchor stability limits.
- Why it matters: DNA-printing of cells needs stable, membrane-anchored DNA that remains functional during patterning, but hydrophobic anchor chemistry can reduce DNA availability and undermine printing simplicity.
- What they did: The study tested cholesterol, tocopherol, and cholesterol–tocopherol DNA anchor/co-anchor chemistries with defined spacer architectures, measuring functional DNA presentation and LD-DPC patterning performance.
- The result: PEG spacer insertion enhanced functional DNA availability and patterning, while cholesterol anchors gave the highest initial surface loading and tocopherol-containing anchors improved spatial dispersion and cell-capture efficiency during printing. Multiple anchor/co-anchor combinations preserved functional DNA at room temperature and in serum-containing media, enabling practical design guidance for stable nucleic-acid-modified cell interfaces.
