Nonviral gene delivery vectors remain less efficient than viral vectors, and their intracellular fate is strongly influenced by the endocytic route they enter. The cell membrane is now understood to contain lipid raft and non-raft domains, and the initial binding domain can determine the primary endocytic vesicle…

Topical ocular drug delivery is limited by tear turnover, corneal and conjunctival barriers, efflux transporters, and poor water solubility of many drug candidates. Lipid-based nanocarriers may improve ocular bioavailability, prolong preocular residence, enhance corneal penetration, and provide controlled release…

Chitosan is attractive for siRNA delivery because it is cationic, biocompatible, biodegradable, mucoadhesive, and permeation-enhancing. However, native chitosan suffers from low solubility at physiological pH, poor buffering capacity, instability in biological fluids, and insufficient endosomal escape, limiting…

Viral vectors give high gene-transfer efficiency but carry risks of immunogenicity, oncogenic transformation, limited cargo capacity, and manufacturing difficulty. Nonviral nanocarriers are safer and cheaper alternatives, but they still suffer from low transfection efficiency because of extracellular and…

Cationic polymers are widely studied as non-viral gene delivery vectors, but their therapeutic potential extends well beyond gene delivery. This review addresses the need for a broader overview of cationic polymers — their synthesis, modification, bioactive properties, architectures, and applications in drug…

PLGA is one of the most successfully developed biodegradable polymers, with FDA and EMA approval for parenteral drug delivery, but a comprehensive overview linking its formulation methods, physicochemical pitfalls, targeting strategies, and applications across multiple diseases was needed. This review presents why…

The immune system can recognise and kill pre-cancer and cancer cells, but surviving tumour cells learn to escape immune surveillance after immunoselection. Cancer immunotherapy aims to overcome these escape mechanisms. Nanomedicine offers tools—nanodiagnostics and nanobiopharmaceuticals—to deliver antigens…

Nanoparticles (NPs) are increasingly used as contrast agents, therapeutics, and delivery vehicles, but their effective delivery into cells and to specific subcellular organelles remains a major challenge. The review addresses fundamental barriers to intracellular NP delivery—plasma membrane, endosomal entrapment…

PLGA has become one of the most attractive biodegradable polymers for drug delivery and tissue engineering, but its degradation and drug-release behaviour depend on many interconnected variables—polymer composition, molecular weight, crystallinity, device geometry, fabrication method, and drug type. A consolidated…

The nuclear envelope remains a major barrier to successful nonviral transfection and gene therapy. After exogenous DNA is delivered to the cytoplasm, it rapidly complexes with cellular proteins that control its intracellular trafficking and nuclear import. Understanding these mechanisms is necessary to improve…

Engineered nanoparticles have shown promise for targeted drug delivery, but first-generation systems (liposomes and polymer–drug conjugates) have not overcome all biological barriers required for effective therapy. Key barriers include opsonisation and RES clearance, inefficient cargo encapsulation and triggered…

PEG is the gold-standard stealth polymer for drug delivery, but its widespread use has revealed possible side effects and complications, including hypersensitivity, altered pharmacokinetics, toxic side products, stress-induced degradation, and non-biodegradability. This review critically discusses PEG’s advantages…

Nanotechnology enables control and manufacture of structures in the nanometer range, and nanoparticles exhibit novel properties that differ from bulk materials. There is a need for targeted drug delivery systems that improve solubility, bioavailability, sustained release, protection from degradation, and…

Conventional drug delivery faces barriers including rapid clearance, poor intracellular uptake, low target specificity, and toxicity. Nanovehicles (NVs)—nanosized particles capable of entering cells and delivering cargo intracellularly—offer a means to overcome these barriers. The review aims to provide an overview…

Gene therapy has enormous therapeutic potential, but delivery remains the central bottleneck. Viral vectors are efficient but carry serious safety, immunogenicity, manufacturing, and cargo-capacity limitations. Nonviral vectors are safer and more scalable but typically orders of magnitude less effective. This Account…

Conventional cancer chemotherapy suffers from poor tumour selectivity, high required doses, systemic toxicity, rapid drug elimination, and multidrug resistance. Polymeric nanoparticles (NPs) are reviewed as a strategy to improve targeted delivery, controlled release, and therapeutic efficacy while reducing adverse…

Systemic non-viral gene delivery is limited by rapid clearance, toxicity, and poor target-cell access. Cationic lipid–DNA lipoplexes are effective in vitro but perform poorly in vivo because they aggregate with serum proteins, are cleared by the reticuloendothelial system (RES), and accumulate mainly in lung and…
