Nanoparticle Delivery Systems in Gene Therapy
Engineered nanoparticles enable precise, tumor-specific delivery of CRISPR, siRNA, mRNA, and plasmid DNA with minimal systemic toxicity.
Nanoparticle-Mediated Gene Delivery Mechanisms
Overcoming biological barriers for efficient nucleic acid transfer in solid tumors.
Nanoparticles (10–200 nm) exploit enhanced permeability and retention (EPR) effect while active targeting via ligands (folate, transferrin, aptamers) achieves >20-fold tumor enrichment. Ionizable lipid nanoparticles (LNPs) dominate mRNA delivery with endosomal escape efficiency >90% at N/P ratio 6:1.
Polymeric systems (PEG-PLA, chitosan) enable sustained release, while gold/silica cores facilitate photothermal synergy. Clinical data from 2025 shows 87% tumor accumulation with PEGylated LNPs vs 12% for naked DNA.
AI-optimized surface chemistry (zeta potential -5 to +15 mV) minimizes opsonization and extends circulation half-life to 18+ hours.
