RNAi therapeutics such as siRNA and miRNA can potently and specifically silence almost any gene, but systemic delivery is limited by poor cell permeation, rapid nuclease degradation, immunogenicity, and lack of target specificity. Lipid-based nanocarriers are among the most biocompatible and clinically advanced…

Non-viral nucleic acid delivery requires carriers that protect DNA/RNA from nucleases and facilitate intracellular delivery. Solid lipid nanoparticles (SLNs) are promising, but the molecular mechanisms by which they assemble with nucleic acids, transfect cells, and release cargo remain poorly understood compared with…

siRNA-based gene therapy is a promising biotechnology for treating cancer and other diseases, but safe and efficient delivery is essential. Nanoparticle-mediated delivery must overcome multiple biological barriers, and endosomal escape is a critical rate-limiting barrier: nanoparticles are typically internalised via…

Current leishmaniasis chemotherapy lacks options that combine high activity, low toxicity, and affordable cost. Oryzalin (ORZ), a dinitroaniline with in vitro antileishmanial activity, is limited by poor water solubility and low accumulation in diseased organs. Lipid-based nanocarriers may overcome these limitations…

Naked RNAi molecules are rapidly degraded by serum nucleases and cannot readily cross cell membranes because of their negative charge. Effective delivery systems are therefore required to exploit RNAi for antiviral therapy. Lipid nanoparticles (LNPs) are attractive because they are relatively safe, simple to produce…

Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) were developed as alternative colloidal carriers with better stability and tolerability than polymeric nanoparticles. However, in vitro toxicity data were scattered across many cell lines, assays, exposure times, concentrations, and formulations…

siRNA has broad therapeutic potential, but clinical translation is limited by rapid nuclease degradation, poor accumulation in target tissues, and inability to cross cell membranes to reach the cytoplasm. Lipid nanoparticles containing ionisable amino lipids are the leading systemic delivery system for siRNA, with…

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…

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…

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…

Transfection efficiency of nonviral gene delivery systems remains unacceptably low, largely due to the inability of plasmid DNA to effectively translocate through the nuclear pore complexes (NPCs). While substantial progress has been made in transcriptionally regulated vectors, control over nuclear targeting is…
