In this study, chitosan (CS)/poly(vinyl alcohol) (PVA) (CS/PVA) blend nanofibers with varying weight ratios and silver (Ag)/copper (Cu)/CS/PVA composite fibers have been prepared successfully by the electrospinning process. The tip-to-collector distance was kept at 15 cm, applied voltage varied from to 25 kV. effects of on morphology diameter were investigated. resultant characterized using sca...

The aim of this study was designing and preparing the chitosan nanoparticles (CS-NPs) loading with snake (Vipera albicornuta) venom as well as evaluating the influence of different factors on the encapsulation efficiency (EE) and loading capacity (LC) of venom. The morphologies and characteristics of CS-NPs were determined by scanning electron microscopy (SEM), Fourier transform infrared spectr...

Hypericum triquetrifolium Turra. (Hypericaceae) is one of the important medicinal plants. This herb used in Turkish folk medicine for its antidepressant, anthelmintic and antiseptic effects. extracts have an commercial value pharmaceutical industry. Therefore, studies to increase amount secondary metabolites it contains are becoming widespread. Elicitors biological non-biological factors that c...

The polymeric nanoparticles are prepared from biocompatible polymers in size between 10-1000 nm. Chitosan is a biocompatible polymer that - can be utilized as drug delivery systems. In this study, chitosan nanoparticles were synthesized using an optimized spontaneous emulsification method. Determining particle size and morphology are two critical parameters in nanotechnology. The aim of this st...

The aim of this study was to investigate the effect of acrylate modification on the mucoadhesion of chitosan at the nanoscale. Nanoparticles were fabricated from acrylated chitosan (ACS) via ionic gelation with tripolyphosphate and were characterized in terms of size, zeta potential, stability, and nanoparticle yield. Chitosan (CS) nanoparticles, serving as a control, were fabricated using the ...

Regeneration deficiency is one of the main obstacles limiting the effectiveness of tissue-engineered scaffolds. To develop scaffolds that are capable of accelerating regeneration, we created a heparin/chitosan nanoparticle-immobilized decellularized bovine jugular vein scaffold to increase the loading capacity and allow for controlled release of vascular endothelial growth factor (VEGF). The va...

CONTEXT Over the last few decades, extensive efforts have been made worldwide to develop nanomedicine delivery systems, especially via oral route for antidiabetic drugs. Absorption of insulin is hindered by epithelial cells of gastrointestinal tract, acidic gastric pH and digestive enzymes. EVIDENCE ACQUISITION Recent reports have identified and explained the beneficial role of several struct...

N-sodium acrylate-O-carboxymethyl chitosan [CMCH-g-PAA(Na)] bound Fe3O4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. CMCH-g-PAA (Na) was obtained by grafting of sodium polyacrylate on O-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegra...

Using a Au nanoparticle/reduced graphene oxide composite (AuNP-RGO), a signal-enhanced electrochemical immunosensor without label was created to detect neuron-specific enolase (NSE). Furthermore, an environmentally-friendly method was developed to prepare AuNP-RGO by employing chitosan (CS), which served as reducing and stabilizing agent. We showed that the sensitivity of the immunosensor desig...
