Efficient and cell-type-specific delivery remains a major barrier to CRISPR-based genome editing in vascular endothelial cells. Here, we systematically evaluate lipid nanoparticle (LNP)-mediated mRNA and CRISPR delivery in human umbilical vein endothelial cells (HUVECs). While a conventional SM-102-based LNP…

Delivering mRNA to the lungs promises treatment of genetic, infectious and non-communicable lung diseases. Yet, conventional lipid nanoparticle formulations lack the stability needed to endure the harsh mechanical stress during nebulization. Additionally, once deposited in the respiratory tract, gene delivery systems…

Four-component lipid nanoparticles (LNPs) represent the leading non-viral vectors for mRNA delivery, but they have limitations including: (1) segregation of the neutral ionisable lipid as droplets in the LNP core, reducing transfection efficiency to ~1-2%; (2) the "PEG dilemma" where PEGylation increases circulation…

Microfluidic mixing can produce precise LNPs but is limited in throughput, while bulk mixing is scalable but yields larger, heterogeneous particles with variable potency. A scalable microfluidic device is needed to produce potent RNA-LNPs across discovery and clinical scales. PMD achieved 18.4 L/h production…

CRISPR/Cas gene-editing components are often encoded on large plasmids (9–19 kb), which are difficult to encapsulate and transfect. Most PLGA nanoparticle (NP) gene-delivery studies use small nucleic acids (siRNA) or small plasmids (<6 kb), and the structural integrity and functional performance of large plasmids in…

PLGA microspheres are widely used for controlled drug release, but they often exhibit pronounced initial or mid-term burst release. A strategy is needed to finely tune drug release kinetics and suppress burst release, especially for water-soluble drugs. MSNs: Average size 119 nm; specific surface area 902.53 m²/g…
