The mechanism by which cationic polymers with titratable amines mediate endosomal escape and cytosolic delivery of nucleic acids remains poorly understood. Buffering capacity alone has often failed to predict transfection efficacy, so this study examines whether the effective pKa of poly(beta-amino ester)s (PBAEs)…

CRISPR-Cas9 gene editing requires efficient intracellular delivery of large cargo. Viral vectors have packaging and production limitations, and nonviral CRISPR plasmid delivery had mainly been studied for single-site knockout, not for gene deletion requiring two cleavage events. The transfection requirements for…

Drug penetration into tumours is limited by abnormal vasculature and high interstitial pressure, and chemotherapy causes undesirable adverse effects including bone marrow and gastrointestinal toxicity. Nanotechnology-based drug delivery systems aim to reduce these adverse effects by enhancing penetration and…

Nanoparticles (NPs) interact extensively with plasma proteins after intravenous administration and are rapidly cleared by the mononuclear phagocyte system (MPS) or complement system, causing premature drug release at off-target sites. A stealth coating layer can improve blood circulation half-life by escaping immune…

mRNA is a flexible and potentially safer cancer immunotherapy platform, but its clinical use has been limited by extracellular instability, poor cellular uptake, and inefficient endosomal escape. Lipid nanoparticles have become the most advanced non-viral delivery system for mRNA, enabling therapeutic vaccines…

LNPs are clinically advanced vectors for siRNA, mRNA, and DNA delivery, but their in vivo behaviour is strongly influenced by the biological environment. Upon administration, biomolecules adsorb to the LNP surface and form a “biomolecular corona,” which defines the particle’s biological identity, affects stability…

Cationic liposomes (CLs) are promising non-viral gene-delivery vectors, but their clinical use in cancer gene therapy is limited by extracellular barriers (opsonisation, RES clearance, poor tumour penetration) and intracellular barriers (endosomal/lysosomal entrapment, restricted cytoplasmic/nuclear transport). The…

Liposomes remain an important nano-sized drug delivery system because of their biomimetic bilayer, ease of preparation, and biocompatibility, but clinical translation is still limited by reproducibility, scale-up, stability, and payload-specific barriers.

Gene therapy is limited by the fragile nature of therapeutic DNA/RNA and by safety concerns with viral vectors. Non-viral polymeric vectors are attractive, but conventional cationic polymers such as PEI, PDMAEMA, and PLL are often non-degradable, causing accumulation, cytotoxicity, and poor gene unpacking. This…

Non-viral gene delivery needs safe and efficient carriers. PBAEs are biodegradable cationic polymers with promising transfection activity, but they face challenges such as instability in physiological fluids, positive-charge toxicity, and limited systemic delivery. This review summarises PBAE properties, advantages…

Cancer is a leading cause of mortality worldwide, and conventional treatments and cytotoxic immunotherapies have limitations. Because tumours are complex and involve multiple genetic and cellular factors in tumorigenesis and metastasis, there is a need for an immunotherapy that targets tumours at both cellular and…

mRNA has broad therapeutic potential for vaccination, protein replacement, and gene editing, but its clinical translation is limited by the need for improved intracellular delivery systems. mRNA is much larger than siRNA or ASOs (~300–5,000 kDa, ~1–15 kb vs ~14 kDa and 4–10 kDa, respectively), making delivery more…

DNA in abnormal cellular compartments (cytosol, endosomes, micronuclei) is a potent danger signal for the innate immune system, primarily known for inducing type I interferons and IL-1β. More recently, it has become clear that cytosolic DNA also triggers various forms of programmed cell death (PCD), but the pathways…

The general perception is that cellular uptake of materials is proportional to cell volume (mass) or surface area, following cubic or square relationships with cell radius. However, experimental data on nanoparticle uptake in MDA-MB 231 breast cancer cells show a linear relationship with cell radius—a result that is…

Fibrosis is observed in nearly every form of myocardial disease and contributes to heart failure, yet clinical interventions targeting fibrosis remain limited. No therapies directly target excessive cardiac fibrosis, and very few interventions improve cardiac function in patients with impaired compliance. Genetic…
