Self-healing polymers can repair damage and recover functionality, potentially extending the lifetime and safety of biomedical devices. Although self-healing hydrogels have been reviewed previously, papers focused specifically on their use in tissue engineering are scarce. This review summarises fabrication methods…

Melanoma is a poorly immunogenic and highly aggressive skin cancer with limited long-term survival for advanced disease. Dendritic cell (DC)-based vaccines are promising immunotherapies, but their efficacy relies on critical factors including DC maturation state and efficient antigen delivery. Nanoparticulate…

Dendritic cell (DC)-based cancer immunotherapy has shown impressive outcomes, including the first FDA-approved anti-cancer vaccine, but clinical application faces challenges such as limited durable responses, antigen selection issues, and immunosuppressive tumour microenvironments. Nanoparticles (NPs) are promising…

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…

Gene therapy requires efficient delivery of genetic material, but viral vectors carry risks of immunogenicity, toxicity, and cancer formation. Cationic polymers such as polyethyleneimine (PEI) can condense DNA and facilitate delivery, but their lack of biodegradation causes significant toxicity due to polymer…

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…

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…

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…

Despite extensive research, therapeutic delivery still faces major barriers: poor plasma stability, rapid clearance by the reticuloendothelial system (RES), and intracellular obstacles such as endosomal entrapment and lysosomal degradation. Biodegradable polymer nanogels (NGs) — physically or chemically cross-linked…

Viral vectors are efficient but carry risks of immunogenicity, inflammatory reactions, recombination, limited DNA cargo capacity, and manufacturing difficulties. Non-viral polymeric vectors are safer and easier to produce, but their transfection efficiency remains much lower than viral vectors because of multiple…

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…

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…

Efficient transfection with low toxicity is essential for nucleic acid therapeutics, but synthetic polycations such as polyethylenimine (PEI) are limited by cytotoxicity. This review critically assesses the safety and efficacy challenges of PEI-based polyplexes, identifies deficiencies in the field, and proposes…

Nucleic acid therapeutics—plasmid DNA, antisense oligonucleotides, and RNAi molecules—have broad therapeutic potential but face major biological barriers, including nuclease degradation, poor membrane penetration, endosomal entrapment, nonspecific biodistribution, and immune activation. The review addresses how…

Polymer-based siRNA delivery is promising but faces limitations similar to polymer-based DNA delivery, yet the two nucleic acids differ fundamentally in size, stiffness, stability, site of action, and duration of effect. This review addresses the need to understand these distinctions so that knowledge from the…

Cationic lipids and polymers are promising non-viral gene delivery vectors because they are non-immunogenic, easy to produce, and not oncogenic, but toxicity remains a major obstacle to their clinical application. The review evaluates structural features of cationic compounds and summarises toxicity–structure…
