Chitosan-based biological macromolecules provide a versatile platform for ocular drug delivery, but their hydrophilic nature limits the encapsulation and sustained release of hydrophobic therapeutics. Here, we designed oleic acid-functionalized chitosan nanoparticles (OA-CS NPs) with tunable hydrophobicity by varying…

The photodynamic therapy (PDT) efficacy is limited by tumor hypoxia and inefficient intracellular accumulation of photosensitizers (PSs). This study reports chitosan-coated solid lipid nanoparticles (SLNs) co-encapsulating the near-infrared photosensitizer IR780 and oxygen-generating CaO 2 nanoparticles (NPs) for…

siRNA therapeutics are limited by poor cellular uptake, serum nuclease degradation, and inefficient endosomal/lysosomal escape. Chitosan is biocompatible and biodegradable but has low transfection efficiency, largely due to poor buffering capacity and weak endosomal escape. Histidine grafting was explored to add…

Lung cancer has the highest mortality among cancers, and single-agent chemotherapy is often unsuccessful due to drug resistance, insufficient intracellular uptake, nonspecific targeting, and severe systemic toxicity. Combination chemotherapy can suppress drug resistance and achieve synergistic anticancer efficacy…

Whole tumour cell lysates (TCL) are a broad source of tumour antigens for cancer vaccines, but soluble TCL is unstable, poorly taken up by dendritic cells (DCs), and inefficient at inducing cytotoxic T lymphocyte (CTL) responses. A delivery system was needed to protect TCL antigens, target DCs, and enhance antigen…

Galectin-1 (Gal-1) is overexpressed in glioblastoma multiforme (GBM), promotes tumour progression, angiogenesis, chemoresistance, and immune suppression. A non-invasive delivery strategy is needed to reach CNS tumours with siRNA while limiting systemic effects. The intranasal route was explored as an underexplored…

Naked siRNA is unstable and inefficient, and chitosan-based carriers are limited by poor solubility at physiological pH and weak endosomal disruption. The study aimed to optimise chitosan nanoparticle formulations for intravenous siRNA delivery that achieve high gene silencing without cytotoxicity and remain stable…

Conventional adjuvants such as Complete Freund’s Adjuvant (CFA) and Incomplete Freund’s Adjuvant (IFA) are potent but toxic, limiting clinical use. A safer, biodegradable adjuvant system was needed to enhance antigen-specific humoral and cellular immunity without severe local or systemic side effects. Safety: CH-HG…

Chemo-immunotherapy combinations are limited by systemic immunotoxicity from cancer drugs and rapid clearance of low-molecular-weight drugs after intratumoral injection. A local, biodegradable delivery system was needed to sustain drug/GMCSF exposure at the tumour site, reduce systemic toxicity, and promote tumour…

siRNA has therapeutic potential, but in vivo delivery is limited by rapid clearance, nuclease degradation, and nonspecific distribution. A tumour-targeted, biocompatible delivery system was needed to increase intratumoral siRNA accumulation, reduce off-target effects, and enable silencing of growth-promoting genes in…

DNA vaccines can induce antibody and CTL responses, but clinical translation is limited by weak potency and the need for high or repeated doses. The study addresses this by targeting DNA to antigen-presenting cells (APCs) and improving endosomal/lysosomal release, using mannose-bearing chitosan microspheres loaded…

siRNA has therapeutic potential but is limited by poor cellular uptake, rapid nuclease degradation, and poor blood stability. Chitosan was explored as a non-viral siRNA vector because of its low toxicity, biodegradability, biocompatibility, and cationic nature, but its use for siRNA delivery had not been…

Conventional adjuvants such as aluminium and Freund’s adjuvants have limitations, including poor cell-mediated immunity and local toxicity. Ginseng stem-leaf saponins (GSLS) have immunomodulatory/adjuvant activity, but improved delivery systems are needed. Cubosomes are stable lipid cubic liquid crystalline…
