To date there has not been any report on catan-ionic hybrid lipidic nano-carriers, let alone a report on applying them to deliver insoluble anti-tumor drugs. Catan-ionic hybrid lipidic nano-carriers containing curcumin (CUR-C-HLN) inherit the merits of catan-ionic systems, hybrid lipidic systems and nano-structured carriers (the second-generation substitute of solid lipidic nano-systems). Catan...

We designed a two-step Pickering emulsification procedure to create nano-encapsulated phase changing materials (NEPCMs) using a method whose simplicity and low energy consumption suggest promise for scale-up and mass production. Surface-modified amphiphilic zirconium phosphate (ZrP) platelets were fabricated as the Pickering emulsifiers, nonadecane was chosen as the core phase change material (...

Cavitand is sufficiently predisposed to form nano-scale capsules in the presence of templating straight-chain hydrocarbons; quaternary complexes are formed when two copies of smaller guests are encapsulated, whilst larger guests form ternary entities.

• Metronidazol-polymer composites were prepared by nano spray drying. In the solid dispersion metronidazol was crystalline and amorphous in polymer matrix. Melting point decrease phenomena observed DSC measurement. Peak broadening XRD analysis. The composite microparticles nanostructured. this study metronidazole drug encapsulated hydroxypropyl methylcellulose polyvinylpyrrolidone polymers from...

OBJECTIVE Intra-articular drug delivery systems still suffer from too short-lasting effects. Magnetic particles retained in the joint using an external magnetic field might prolong the local release of an anti-inflammatory drug. For the purpose, superparamagnetic iron oxide nanoparticles (SPIONs) and dexamethasone 21-acetate (DXM) were co-encapsulated into biodegradable microparticles. METHOD...

the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

Resistance to aspirin and its cytotoxicity significantly limits its therapeutic applications. Nano-liposomal encapsulation of aspirin can reduce its cytotoxicity. In this study, aspirin encapsulated nano-liposomes (AS-NL) was prepared and its performance in drug delivery and cytotoxicity was evaluated. The effects of two independent variables including: number of freeze/thawing cycles and conce...

Conventional micromolding provides rapid and low-cost methods to fabricate polymer microstructures, but has limitations when producing sophisticated designs. To provide more versatile micromolding techniques, we developed methods based on filling micromolds with polymer microparticles, as opposed to polymer melts, to produce microstructures composed of multiple materials, having complex geometr...
