Special Issue Information

Dear Colleagues,

We are pleased to invite submissions to this Special Issue, entitled “Recent Advances in Non-Viral Vectors for Gene Therapy and Gene Delivery”. Non-viral platforms have progressed from exploratory formulations to clinically validated vehicles for mRNA and siRNA, while the efficient, tissue-selective delivery of genome editors and antisense cargos remains a central bottleneck. Addressing this challenge requires a quantitative understanding of transport across physiological barriers, productive cellular uptake, endosomal escape, and intracellular trafficking, together with manufacturability, stability, and quality attributes that enable translation.

This Special Issue aims to collate mechanism-anchored research that advances the efficacy, specificity, and safety of non-viral gene delivery vectors, positioned within the core disciplines of formulation science, biopharmaceutics, pharmacokinetics, and nanomedicine. We welcome submissions of multidisciplinary research that integrates materials design with data science, microfluidics, automation, or advanced imaging, encompassing lipid-, polymer-, peptide-, extracellular vesicle-, and inorganic-based carrier platforms.

For this Special Issue, original research articles and reviews are welcome to be submitted. Research areas may include, but are not limited to, the following:

  • Lipid, polymer, peptide, extracellular vesicle, and inorganic carrier platforms;
  • Tissue-selective targeting, biodistribution, and barrier traversal in vivo;
  • Cellular uptake pathways, endosomal escape mechanisms, and organelle routing;
  • Immune interactions, reactogenicity mitigation, and tolerability profiling;
  • Scalable manufacturing and CMC, including stability and analytical release testing;
  • Microfluidic synthesis, process intensification, and quality-by-design;
  • Quantitative PK/PD modeling, systems analysis, and imaging-guided tracking;
  • Delivery of CRISPR/Cas systems, base/prime editors, and antisense oligonucleotides;
  • mRNA and self-amplifying RNA vaccines, protein replacement, and gene modulation.

I look forward to receiving your contributions.

Lipid nanoparticles are a clinically validated platform for delivering nucleic acids, but performance is constrained by multiscale physiological barriers spanning circulation, vascular interfaces, extracellular matrices, cellular uptake, and intracellular trafficking. This review links composition–structure–function relationships for ionizable lipids, helper phospholipids, cholesterol, and PEG-lipids to systemic fate, endothelial access, endosomal escape, cytoplasmic stability, and nuclear transport. We outline strategies for tissue and cell targeting, including hepatocyte ligands, immune and tumor selectivity, and selective organ targeting through compositional tuning, together with approaches that modulate escape using pH-responsive chemistries or fusion-active peptides and polymers. We further examine immunomodulatory co-formulation, route and schedule effects on biodistribution and immune programming, and manufacturing and stability levers from microfluidic mixing to lyophilization. Across these themes, we weigh trade-offs between stealth and engagement, potency and tolerability, and potency and manufacturability, noting that only a small fraction of endosomes supports productive release and that protein corona variability and repeat dosing can reshape tropism and clearance. Convergence of standardized assays for true cytosolic delivery, biomarker-guided patient selection, and robust process controls will be required to extend LNP therapeutics beyond the liver while sustaining safety, access, and scale.
