Hollow chitosan/alginate nanocapsules for bioactive compound delivery.
This work aimed at the development of biodegradable nanocapsules as carriers of two bioactive compounds, 5-aminosalycilic acid and glycomacropeptide. Nanocapsules were produced through layer-by-layer (LbL) deposition of chitosan (CH) and alginate (ALG) layers on polystyrene nanoparticles. The bioactive compounds were incorporated on the third layer of the nanocapsules being its encapsulation ef...
متن کاملAIE luminogen bridged hollow hydroxyapatite nanocapsules for drug delivery.
A new type of organophosphonic acid, (4,4'-(1,2-diphenylethene-1,2-diyl)bis(4,1-phenylene))bis(methylene)diphosphonic acid (PATPE), based on tetraphenylethene has been prepared, and its ester derivative exhibits the characteristic property of aggregation-induced emission (AIE) in DMSO-H2O solution. The PATPE is then fabricated into hydroxyapatite by a one-pot condensation process to form hollow...
متن کاملMultifunctional mesoporous hollow silica nanocapsules for targeted co-delivery of cisplatin-pemetrexed and MR imaging.
The development of theranostic mesoporous hollow silica nanospheres having therapeutic and diagnostic functions has been achieved. The exterior surface of the hollow mesoporous silica nanosphere was selectively acid functionalized and utilised to conjugate the anticancer drug cisplatin, the marker molecule folic acid (FA), and rhodamine isothiocyanate (RITC), whereas the interior space was util...
متن کاملCPMV-induced synthesis of hollow mesoporous SiO2 nanocapsules with excellent performance in drug delivery.
Hollow mesoporous-SiO2 nanocapsules have been synthesized at room temperature using unmodified cowpea Mosaic Virus (CPMV) as a template, and without using any catalyst or surfactant during the synthesis. The average size of the capsules synthesized was ∼200-250 nm with a 60-100 nm hollow core. The resulting nanocapsules were characterized using high resolution transmission electron microscopy (...
متن کاملPolymer-based nanocapsules for drug delivery.
A review of the state of knowledge on nanocapsules prepared from preformed polymers as active substances carriers is presented. This entails a general review of the different preparation methods: nanoprecipitation, emulsion-diffusion, double emulsification, emulsion-coacervation, polymer-coating and layer-by-layer, from the point of view of the methodological and mechanistic aspects involved, e...
