Nanoscale particles offer a variety of interesting properties, and there is growing interest in their assembly into higher ordered structures. We report that the pH-responsive aminopolysaccharide chitosan can mediate the electrodeposition of model nanoparticles. Chitosan is known to electrodeposit at the cathode surface in response to a high localized pH. To demonstrate that chitosan can mediat...

In this study, response surface methodology (RSM) was carried out with four parameters: chitosan concentration, AgNO3 ascorbic acid concentration and time the objective to obtain minimum mean particle size of silver nanoparticles (response Y). The chitosan-silver nanoparticle composite material (CTS-AgNPs nanocomposite) obtained experimentally from optimal conditions characterized by evaluating...

Magnetic chitosan nanoparticles were prepared by the suspension cross-linking technique for use in the application of magnetic carrier technology. The Fe3O4 magnetic nanoparticles were synthesized by co-precipitation of FeCl2 and FeCl3 solution in base medium for using in the preparation of the magnetic chitosan. The morphological and magnetic properties of the magnetic nanoparticles were chara...

Abstract In this work, new chitosan-based Schiff bases were synthesized by the reaction of chitosan with quinolinone and pyranoquinolinone giving CSQ , CSP respectively. The novel Chitosan grafted on silver nanoparticles providing CSQ/Ag CSP/Ag structures. Characterization isolated compounds was carried out FT-IR, TGA, XRD, SEM, TEM. target evaluated as antitumor agents against three cancer cel...

This study reports that tumor-targeting glycol chitosan nanoparticles with physically loaded and chemically conjugated photosensitizers can be used in photodynamic therapy (PDT). First, the hydrophobic photosensitizer, chlorin e6 (Ce6), was physically loaded onto the hydrophobically-modified glycol chitosan nanoparticles (HGC), which were prepared by self-assembling amphiphilic glycol chitosan-...

background and objectives: the most prevalent and worldwide oral disease is dental caries that affects a significant pro- portion of the world population. there are some classical approaches for control, prevention and treatment of this pathologic condition; however, the results are still not completely successful. therefore new methods are needed for better management of this important challen...
