The major issues of self-assembled nanoparticles as drug carriers for cancer therapy include biostability and tumor-targetability because the premature release from nonspecific accumulation drug-loaded may cause undesirable toxicity to normal organs lower therapeutic efficacy. In this study, we developed robust tumor-targeted nanocarriers based on an amphiphilic hyaluronic acid (HA)-polycaprolactone (PCL) block copolymer, in which HA shell was cross-linked via a bioreducible disulfide...

Bioreducible carboxymethyl dextran (CMD) derivatives are synthesized by the chemical modification of CMD with lithocholic acid (LCA) through a disulfide linkage. The hydrophobic nature LCA allows conjugates (CMD‐SS‐LCAs) to form self‐assembled nanoparticles in aqueous conditions. Depending on degree substitution, particle diameters range from 163 242 nm. Doxorubicin (DOX), chosen as model anticancer drug, is effectively encapsulated into high loading efficiency (>70%). In vitro optical...

Optically active nanomaterials have shown great promise as a nanomedicine platform for photothermal or photodynamic cancer therapies. Herein, we report gold-nanoclustered hyaluronan nanoassembly (GNc-HyNA) photothermally boosted tumor ablation. Unlike other supramolecular gold constructs based on nanoparticle building blocks, this system utilizes the of amphiphilic conjugates drug carrier hydrophobic therapy agent verteporfin, polymeric reducing agent, and an organic nanoscaffold upon which...

Plant-derived vesicles (PDVs) are membranous structures that originate from plant cells and responsible for multiple physiological pathological functions. In the last decade, PDVs have gained much attention their involvement in different biological processes, including intercellular communication defense response, recent scientific evidence has opened a new avenue applications cancer treatment. Nevertheless, remains unknown about these vesicles, current research inconsistent. This review...

RNA nanotechnology, including rolling circle transcription (RCT), has gained increasing interest as a fascinating siRNA delivery nanoplatform for biostable and tumor-targetable RNA-based therapies. However, due to the lack of fine-tuning technologies nanostructures, relationship between physicochemical properties efficacy polymeric nanoparticles (PRNs) with different sizes not yet been fully elucidated. Herein, we scrutinized effects size/surface chemistry-tuned PRNs on biological...

Inflammatory bowel disease (IBD) is a chronic disorder characterized by recurrent gastrointestinal inflammation, lacking precise aetiology and definitive cure. The gut microbiome vital in preventing treating IBD due to its various physiological functions. In the interplay between human health, extracellular vesicles secreted bacteria (BEVs) are key mediators. Herein, we explore role of Roseburia intestinalis (R)-derived EVs (R-EVs) as potent anti-inflammatory mediators dextran sulfate...

Abstract Extracellular vesicles (EVs) are essential mediators in intercellular communication that have emerged as natural therapeutic nanomedicines for the treatment of intractable diseases. Their applications, however, been limited by unpredictable vivo biodistribution after systemic administration. To control fate EVs, their surfaces should be properly edited, depending on target site action. Herein, based bioorthogonal copper‐free click chemistry (BCC), surface‐edited EVs were prepared...

Although conventional topical approaches for treating psoriasis have been offered as an alternative, there are still unmet medical needs such low skin-penetrating efficacy and off-target adverse effects. A hyaluronic acid nanoparticle (HA-NP) formed by self-assembly of HA-hydrophobic moiety conjugates has broadly studied a nanocarrier long-term target-specific delivery drugs, owing to their excellent physicochemical biological characteristics. Here, we identify HA-NPs therapeutics using in...
