This study described the performance of carbon nanofiber modified chitosan (CNF@CS) composite microspheres for controlled release Ibrutinib (IBR) drug. The surface morphology, particle sizes, and functional group contents were characterized by attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), scanning electron, optical microscopy measurements. obtained data demonst...

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 research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934p as mucoadhesive polymer and ethyl cellulose as carrier ...

Novel bioresorbable fiber/microsphere composite structures loaded with proteins were developed and studied. These unique polymeric structures are designed to combine good mechanical properties with a desired controlled protein-release profile, in order to serve as scaffolds for tissue regeneration applications. The composite fiber structures were formed by "coating" poly(L-lactic acid) fibers w...

This paper introduced a process to prepare the carbon nanosphere (CNS)/NiCo2O4 core-shell sub-microspheres. That is: 1) CNSs were firstly prepared via a simple hydrothermal method; 2) a layer of NiCo2O4 precursor was coated on the CNS surface; 3) finally the composite was annealed at 350 °C for 2 hours in the air, and the CNS/NiCo2O4 core-shell sub-microspheres were obtained. This core-shell su...

Regular arrays of TixSn11xO2 nanostructures were produced through glancing angle sputter deposition onto self-assembled close-packed arrays of 200-nm-diameter and 1-μm-diameter polystyrene microspheres respectively. The anisotropic nanoflakes grown on 200-nm-diameter polystyrene microspheres exhibited macroscopic-wetting anisotropy, with the apparent contact angle observed parallel to the direc...

Stimuli-responsive materials undergo structural changes in response to an external trigger (i.e., pH, heat, or light). This process has been previously used for a range of applications in biomedicine and microdevices and has recently gained considerable attention in controlled drug release. Here, we use a near-infrared (NIR) light responsive polymer-nanorod composite whose glass transition temp...

The importance of promising composites in modern materials science is constantly increasing. use various fillers or additives associated with their influence not only on the defining properties composite, but also physical and mechanical characteristics material. In this case, distribution additive its wetting a polymer play an important role. problem highlighted article different copper-contai...

objective(s): the purpose of the current study was to assess the feasibility of microspheres from biocompatible polymer for oral bioavailability (ba) enhancement of potent sulfonamide- type loop diuretic- furosemide - which used in the treatment of congestive heart failure, caused edema, cirrhosis, renal disease and as an adjunct in acute pulmonary edema. the comparatively poor and inconstant b...
