Conventional systemic drug administration suffers from low site-specific bioavailability, unfavourable biodistribution, poor target accumulation, and adverse side effects. There is a need for carrier-based systems that enable localised and targeted delivery, improve therapeutic efficacy, and reduce toxicity…

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…

While many reviews have systematically covered different types of formulation materials for gene delivery, a parallel comparison of different formulation materials together with an analysis of the correlation between their material properties and nucleic acid delivery functions has not been conducted. Understanding…

Many emerging therapies require delivery of biological cargo into the cytosol, but nanoparticle delivery systems are hindered by entrapment and degradation in the endo/lysosomal pathway. Endosomal escape remains a rate-determining step for non-viral delivery. The review highlights the need for greater understanding…

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…

PLGA is a biocompatible, biodegradable copolymer widely used in drug delivery systems (DDS), but conventional bulk synthesis methods suffer from poor control over particle size, broad size distribution, low drug loading/encapsulation efficiency, and burst release. Microfluidic systems offer a tightly controlled…

Endosomal escape remains a major roadblock for delivering biological therapeutics such as DNA, siRNA, and proteins. Polymeric nanoparticles can protect cargo and target cells, but they often remain trapped in endosomal/lysosomal compartments, where cargo is degraded. A better understanding of how nanoparticle…

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…

Cationic lipids are widely used non-viral gene delivery vectors, but their toxicity remains a major bottleneck for clinical translation. Cytotoxicity is strongly associated with the cationic headgroup structure, yet the relationship between headgroup chemistry and toxic mechanisms has been rarely studied. IC50…

Gene therapy has enormous therapeutic potential, but clinical translation is limited by the delivery problem: nucleic acids are negatively charged, unstable, and must overcome multiple biological barriers to reach their intracellular site of action. Viral vectors are efficient but suffer from immunogenicity, limited…

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…

Cancer stem cells (CSCs) drive tumour heterogeneity, drug resistance, recurrence, and metastasis, limiting conventional chemo/radiotherapy. Liposomal drug delivery systems (LDDSs) are biocompatible, versatile nanocarriers that may overcome CSC-mediated resistance, but their clinical translation remains limited by…

Biodegradable polymeric nanoparticles have great potential to improve cancer therapy by enabling targeted delivery, triggered release, and reduced off-target toxicity. This review addresses how such nanocarriers can be engineered to overcome systemic, organ-level, and cellular barriers and to target cancer cells…

Nucleic acids can be used to engineer the immune system, but their clinical use requires better specificity and intracellular delivery efficiency. Viral vectors have manufacturing, cargo-capacity, safety, and immunological drawbacks; therefore, polymers are being developed as non-viral delivery vehicles whose…

PLGA-based nanoparticles are widely investigated for cancer therapy, but their clinical translation remains limited. A consolidated overview was needed of how PLGA NP physicochemical properties, biological behaviour, targeting strategies, and combination therapies interact—and why promising preclinical results have…

Productive gene transfer requires plasmid DNA to not only enter cells but also traffic through the cytoplasm and cross the nuclear envelope. Most transfection strategies focus on membrane entry and promoter choice, but cytoplasmic trafficking and nuclear import are critical, rate-limiting barriers—especially because…

Nanoparticle-based gene delivery methods are promising for transfecting immune cells, but their impact on basic immune functions such as proliferation—a cornerstone of cellular immunity—has not been systematically investigated. Understanding whether transfection reagents non-specifically influence immune cell…

Surface PEGylation of nanoparticles (NPs) improves circulation time and tumour accumulation but also hinders intracellular delivery, creating the "PEG dilemma" for siRNA therapeutics. While stimuli-responsive de-PEGylation strategies exist, they add complexity to NP design and synthesis. A tunable, serum…

Polyethylenimine (PEI)-based gene delivery is limited by cytotoxicity, rapid degradation, and low cellular uptake. A safer, more stable non-viral system was needed for both gene delivery and gene knockdown. Physicochemical properties: DDC liposomes ~198.7 nm, ζ = −30.9 mV; IPEI polyplexes ~166.2 nm, ζ = +19.1 mV…

Nonviral gene delivery lacks molecularly well-defined carriers suitable for rigorous structure–activity relationship (SAR) studies. Viral vectors raise immunogenicity, cost, and cargo-size concerns, while polymers, dendrimers, and cationic lipids are often polydisperse or supramolecularly ill-defined. The review…

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…
