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…

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…

Nucleic acid analogs and genome-editing proteins have broad therapeutic potential, but clinical translation is limited by poor cell- and organ-specific delivery, endosomal entrapment, enzymatic degradation, and short bioavailability. The review examines lipid- and polymer-based non-viral vectors as strategies to…

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…

T cells are an important target for ex vivo gene delivery and editing, but most commercial reagents cannot transfect them and cationic polymers show only moderate success. The specific intracellular barriers limiting non-viral gene delivery to human T cells are poorly understood, hindering rational polymer design…

CAR-T cell therapy relies mainly on retroviral/lentiviral vectors, which carry risks of carcinogenicity and complex manufacturing. PiggyBac transposon systems offer a safer, simpler non-viral alternative for stable transgene expression, but primary T lymphocytes are difficult to transfect efficiently. A polymeric…

Endosomal escape is a key but poorly quantified step for intracellular nucleic acid delivery. Existing methods are low-throughput, indirect, or fail to distinguish endosomal disruption from actual cytosolic cargo delivery. A reliable, sensitive method is needed to rationally optimise polymeric mRNA delivery vehicles…

Magnesium ions (Mg²⁺) promote bone regeneration, but their effects are strongly concentration-dependent: too little has minimal effect, while excess Mg²⁺ can impair osteoblast activity and bone metabolism. There is no well-established bone tissue engineering scaffold that precisely controls local Mg²⁺ release…

Nonviral gene delivery remains limited by low transfection efficacy, especially under physiological serum conditions and at low nanoparticle doses. Although linear poly(β-amino ester)s (PBAEs) are effective, branching structure had not been systematically evaluated in well-defined PBAE-like poly(ester amine) systems…

Triple-negative breast cancer (TNBC) lacks effective targeted therapy. Nonviral co-delivery of an anticancer drug and a therapeutic gene may improve treatment, but efficient tumour-targeted co-delivery remains challenging. TRAIL has shown limited clinical benefit alone, and embelin (EMB) can inhibit XIAP to promote…

Ideal cancer nanomedicines need a stealth surface for prolonged circulation and tumour accumulation, but stealth surfaces often hinder cellular uptake. Conversely, cationic or targeting-ligand surfaces enhance uptake but cause rapid clearance and off-target interactions. This review addresses the central conflict…

Genetic and rare diseases (GARDs) affect more than 350 million patients worldwide, and many lack effective treatments. RNA-based therapeutics—siRNA, mRNA, miRNA, lncRNA, and RNA-containing genome editing systems—are promising, but naked RNA has poor cellular penetration, is degraded in biological fluids, and does not…
