the purpose of this study was to prepare and characterize nimodipine loaded microspheres using ethyl cellulose (ec) as a carrier polymer through an emulsion solvent evaporation method. these evaluations characterized the pattern of drug release from prepared microspheres. nimodipin loaded microspheres were prepared using an emulsification solvent evaporation method. the effect of process variab...
The purpose of this study was to assess the effect of various formulation parameters on anti-CD205 antibody decorated poly(d, l-lactide co-glycolide) (PLGA) nanoparticles (NPs) in terms of their ability to target dendritic cells (DCs). In brief, emulsification solvent evaporation technique was adapted to design NP formulations using two different viscosity grades (low and high) of both ester an...
Emulsification method is one of the popular methods for producing materials used inbiosensing, bioimaging and others, especially, drug delivery polymer systems in microsize andnanosize. The concrete techniques related to this are emulsification, self-emulsification,in a combination with solvent evaporation process, homogenization, or ultranosication. Thestructure emulsion formulation consists t...
Diclofenac sodium is a Non-Steroidal Anti-inflammatory Drug, active against relief from pain and inflammation. The main objective of this research work was to prepare Ethyl Cellulose microsphere loaded with Diclofenac and invitro drug release study. In the present study, emulsion Solvent Evaporation Method is used for preparing microsphere. The polymer (EC) and drug (Diclofenac Sodium) was diss...
In this work, polyvinylchloride (PVC) membrane prepared via casting solution technique and phase inversion method. N, N dimethylacetamide (DMAC) was used as primary solvent and Tetrahydrofuran (THF) was used as a co-solvent. The effects of parameters such as membrane thickness, evaporation time of casting film before immersion precipitation and addition of polyethylenglchol (PEG) on PVC membran...
One approach for the enhancement of oral drug bioavailability is the technique of nanoparticle preparation. Risedronate sodium (Biopharmaceutical Classification System Class III) was chosen as a model compound with high water solubility and low intestinal permeability. Eighteen samples of risedronate sodium were prepared by the solvent evaporation technique with sodium dodecyl sulfate, polysorb...
In this work, we propose a novel method to fabricate polymer particles with controlled morphology in microchannel by solidification of polymer solutions and study the transition in the shape of these particles from spheres, to cups, and to donuts. The non-spherical geometries are achieved through nonuniform diffusion of the solvent, leading to non-uniform solidification. By adjusting the flow r...
Natural plant extracts have been shown as effective and attractive dental biomaterials with promising properties for restorative/reparative procedures. These bioactive extracts, however, may lose their stability when exposed to air, moisture, or light, if not well-protected. Here, we present a novel technique for sequestering bioactive extracts within polymer microcapsules for long-term stabili...
