miRNAs can regulate about 60% of protein-coding genes and enable targeting of previously “undruggable” proteins and diseases, but their clinical use is limited by nuclease degradation, poor tissue targeting, inefficient cellular uptake, and inadequate cytosolic release. Lipid nanocarriers are a versatile…

In the past 10 years, many clinical nano-gene therapy trials have been discontinued due to poor efficacy and serious side effects. There is a critical need to design suitable gene delivery systems that can protect nucleic acids, enhance transfection efficiency, penetrate deep into tumours, and remain stable and safe…

mRNA-based cancer vaccination is a promising approach for personalised immunotherapy, but safe and effective mRNA delivery remains a major challenge due to mRNA's instability and poor cell membrane permeability. While lipid nanoparticles (LNPs) are the primary delivery strategy, they have limitations with respect to…

Efficient mRNA delivery to lymphocytes remains a major unmet need for immunotherapy and vaccinology. Current methods rely largely on physical transfection such as electroporation, which is ex vivo, costly, and inefficient; chemical vectors generally achieve low lymphocyte mRNA transfection, especially in vivo. Lead…

Free siRNA, mRNA, pDNA, and CRISPR/Cas9 components are rapidly degraded and cleared, so delivery systems are required. LNPs are the most clinically advanced non-viral siRNA carriers; Patisiran reached Phase III and market application in late 2017. The field needed a clearer understanding of LNP design parameters and…

Nanoparticles (NPs) are increasingly used in consumer goods, electronics, and pharmaceuticals, but their beneficial and/or deleterious effects ultimately arise from interactions at the cellular and subcellular level. While many NPs require safe entry into cells for therapeutic efficacy, efficient and controlled…

Topical fungal infections, including ocular mycoses, are increasing, and voriconazole (VCZ) is an effective antifungal but has poor water solubility, limiting liquid ophthalmic formulations. Lipid-based nanoparticles (LNPs/SLNs) may improve VCZ solubility, loading, and topical delivery. Optimised formulation (SLN2)…

mRNA therapeutics have enormous potential for vaccines, cancer immunotherapy, protein replacement, and gene editing, but widespread clinical application is limited by the lack of safe and effective delivery vehicles. Naked mRNA is large (~10⁵–10⁶ Da), densely negatively charged, and rapidly degraded by nucleases; its…

Current cancer immunotherapy shows promise but fails across many tumour types, likely because single-pathway treatments cannot overcome the complex immunosuppressive tumour microenvironment (TME). Lipid-based nanoparticles (LNPs) may allow simultaneous, temporally coordinated delivery of multiple immune modulators to…

Delivery of therapeutics to the CNS is severely limited by the blood–brain barrier (BBB). Polymeric and inorganic nanoparticles have shown utility but face toxicity, scalability, and organic-solvent concerns. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are biocompatible lipid-based…

Genetic drugs such as siRNA, mRNA, and plasmid DNA could treat most diseases by silencing pathological genes, expressing therapeutic proteins, or enabling gene editing. However, naked RNA/DNA is rapidly degraded, does not accumulate in target tissues, and cannot cross cell membranes efficiently. Lipid nanoparticles…
Read the articleLiposomes are attractive pharmaceutical carriers because they encapsulate hydrophilic and hydrophobic drugs and are biocompatible and biodegradable. However, conventional liposomes suffer from aggregation/fusion, premature payload release, rapid clearance by the mononuclear phagocyte system (MPS), low entrapment…
Read the articleRNA interference (RNAi) therapeutics have shown potential for treating genetic, viral, and cancerous diseases, but the main bottleneck remains delivery of functional RNA molecules into the cell cytoplasm. The review focuses on liposomes and other lipid carriers, and on exosomes/extracellular vesicles (EVs), as…

Endosomal escape is widely considered the rate-limiting bottleneck for cytoplasmic delivery of nucleic acids, proteins, and other therapeutics using polymeric and lipid nanoparticles. The field lacks robust methods to quantify escape efficiency and understand its mechanisms, limiting rational design of improved…

mRNA therapeutics have broad potential for protein replacement therapy, cancer immunotherapy, and genomic engineering, but effective intracellular delivery remains a major challenge. A chemically diverse suite of delivery materials—originally developed for DNA and siRNA transfection—has recently shown promise for…

miRNA-based therapeutics are limited by instability, poor cellular uptake, lack of targeting, and potential immune activation. No nonviral miRNA delivery strategy had been explored as a standalone treatment for HER2-positive metastatic breast cancer. HA-LNP uptake was significantly higher than naked FITC-dextran and…

Glioblastoma multiforme (GBM) has a poor prognosis due to limited drug delivery across the blood–brain barrier (BBB), therapeutic resistance, and recurrence. Nanocarriers may improve temozolomide (TMZ) delivery, but it is unclear which nanocarrier type—polymeric nanoparticles (PNPs), solid lipid nanoparticles (SLNs)…

Peptide and protein therapeutics are highly potent but mostly require parenteral administration because they are degraded in the gastrointestinal tract, poorly permeate the intestinal epithelium, and have low oral bioavailability. Lipid-based nanocarriers are a promising strategy to enable oral peptide delivery by…

Cationic gene carriers can mediate cellular uptake but often show poor post-nuclear transcription/translation, toxicity, and aggregation in blood. The study aimed to develop a systemically applicable, tumour-targeting gene carrier that is neutral in blood/cytosol but becomes cationic in endosomes for endosomal…
