Cyclodextrin based nanosponges for pharmaceutical use: a review.
Nanosponges are a novel class of hyper-crosslinked polymer based colloidal structures consisting of solid nanoparticles with colloidal sizes and nanosized cavities. These nano-sized colloidal carriers have been recently developed and proposed for drug delivery, since their use can solubilize poorly water-soluble drugs and provide prolonged release as well as improve a drug's bioavailability by ...
متن کاملCyclodextrin-based nanosponges as drug carriers
Cyclodextrin-based nanosponges, which are proposed as a new nanosized delivery system, are innovative cross-linked cyclodextrin polymers nanostructured within a three-dimensional network. This type of cyclodextrin polymer can form porous insoluble nanoparticles with a crystalline or amorphous structure and spherical shape or swelling properties. The polarity and dimension of the polymer mesh ca...
متن کاملPhase-controlled supramolecular photochirogenesis in cyclodextrin nanosponges.
Pyromellitate-bridged cyclodextrin nanosponges (CDNSs) evolved from sol into gel state upon gradual increase of the concentration from 0.2 to 2000 mg mL(-1) in water. The enantiodifferentiating geometrical photoisomerizations of (Z)-cyclooctene and (Z,Z)-1,3-cyclooctadiene sensitized by CDNS at various concentrations were critically affected by the phase transition of CDNS to afford the corresp...
متن کاملNanosponges: A New Era in Drug Delivery : Review
Effective targeted drug delivery has been a long-held ambition but they are restricted in their utility due to several major drawbacks. The advent of nanotechnology lead to invention of many dosage forms, to circumvent the above limitations, a practical approach has been developed for the formation of discrete functionalized particles, which have been termed as ‘nanosponges’. Nanosponges are ti...
متن کاملDynamics and interactions of ibuprofen in cyclodextrin nanosponges by solid-state NMR spectroscopy
Two different formulations of cyclodextrin nanosponges (CDNS), obtained by polycondensation of β-cyclodextrin with ethylenediaminetetraacetic acid dianhydride (EDTAn), were treated with aqueous solutions of ibuprofen sodium salt (IbuNa) affording hydrogels that, after lyophilisation, gave two solid CDNS-drug formulations. 1H fast MAS NMR and 13C CP-MAS NMR spectra showed that IbuNa was converte...
