Development and Characterization of Poly (ε-caprolactone) Microspheres Containing Acetazolamide
The aim of this study was to prepare and evaluate poly(ε-caprolactone) (PCL) microspheres containing acetazolamide. Microspheres were prepared by solvent evaporation method. The influence of formulation factors (polymer: drug ratio, aqueous: oil phase ratio, concentration of aqueous phase, stirring speed and stirring time) on morphology, particle size, encapsulation and recovery efficiency were...
متن کاملFormation of Poly(ethylene glycol)-Poly(ε-caprolactone) Nanoparticles via Nanoprecipitation
Size control of therapeutic carriers in drug delivery systems has become important due to its relevance to biodistribution in the human body and therapeutic efficacy. To understand the dependence of particle size on the formation condition during nanoprecipitation method, we prepared nanoparticles from biodegradable, amphiphilic block copolymers and investigated the particle size and structure ...

In this study, using biodegradable polymers, nanofiberouse scaffolds were fabricated from the layer-by-layer electrospinning method, including two layer that poly (ε-caprolactone), polyvinylpyrrolidone deposited at first layer and poly (ε-caprolactone), polyvinyl alcohol , β-tricalcium phosphate at latter. After prepration of scaffolds, scanning electron microscopy (SEM), swelling, porosity, me...
متن کاملPreparation and Characterization of Nanoparticles Using Poly(N-isopropylacrylamide)- Poly(ε-caprolactone) and Poly(ethylene glycol)-Poly(ε-caprolactone) Block Copolymers with Thermosensitive Function
Thermosensitive nanoparticles were prepared via the self-assembly of two different poly(ε-caprolactone)-based block copolymers of poly(N-isopropylacrylamide)-b-poly(ε-caprolactone) (PNPCL) and poly(ethylene glycol)-b-poly(ε-caprolactone) (PEGCL). The self-aggregation and thermosensitive behaviors of the mixed nanoparticles were investigated using 1H-NMR, turbidimetry, differential scanning micr...
