Phenylacetyl-peptide amphiphiles were designed, which upon cleavage by a disease-associated enzyme reconfigure from micellar aggregates to fibres. Upon this morphological change, a doxorubicin payload could be retained in the fibres formed, which makes them valuable carriers for localised formation of nanofibre depots for slow release of hydrophobic anticancer drugs.

Nitrogen fertilizer delivery inefficiencies limit crop productivity and contribute to environmental pollution. Herein, we developed Zn- and Fe-doped hydroxyapatite nanomaterials (ZnHAU, FeHAU) loaded with urea (∼26% N) through hydrogen bonding and metal-ligand interactions. The nanomaterials attach to the leaf epidermal cuticle and localize in the apoplast of leaf epidermal cells, triggering a slow N release at acidic conditions (pH 5.

Coumarins, a group of naturally occurring compounds, have been reported to demonstrate anticancer potential. These substances, distinguished by their combined benzene and α-pyrone rings, have been demonstrated to impact multiple cellular mechanisms essential for the initiation and advancement of cancer. These agents work in different ways that prevent different tumor cells from growing, spreading, and increasing.

Systemic administration of methotrexate (MTX), widely regarded as one of the most effective treatments for psoriasis, poses significant challenges due to its high toxicity, limited solubility, and potential for adverse effects. Consequently, developing a topical form of MTX may offer a safer and more effective strategy for psoriasis management. Silk fibroin (SF), a protein-based biomacromolecule, has shown considerable promise as a nanocarrier for sustained and targeted drug delivery, owing to its exceptional physicochemical and biological properties.

Objectives: The aim of this study was to ivnestigate the effect of simulated gastrointestinal viscosity, surface tension, and pH on the dissolution rate of two commercial candesartan cilexetil (CC) products.
Materials And Methods: dissolution of two commercial CC products and immediate release of 16 mg of CC were applied under two conditions: (1) the requirements of the United States Pharmacopeia (USP) and (2) conditions physiologically related to the gastrointestinal tract mimicking viscous food intake. The solubility of CC in different simulation fluids was also measured.

Chlorine dioxide (ClO) gas has attracted considerable attention due to its safety and efficiency. In this study, we successfully developed a color-variable ClO slow-releasing card for postharvest litchi. The optimal ClO slow-releasing card was prepared as follows: Card A was soaked in 2.
