Revolutionary LNP-SNAs Triple CRISPR Delivery Efficiency

9/24/2025

Summary

Story summary

Northwestern University researchers developed lipid nanoparticle spherical nucleic acids (LNP-SNAs) to improve CRISPR delivery.
LNP-SNAs enter cells threefold more efficiently than standard lipid nanoparticles and reduce toxicity.
Lab tests show gene-editing efficiency up threefold and precise DNA repair up 60%.
The study uses CRISPR-associated transposons (CASTs) with high-throughput screening, including V-K CAST mutations that boost activity fivefold while preserving specificity.
