The specific electrical conductivity and dielectric constant of aqueous solutions of ionic aminopolysaccharide chitosan in L-aspartic acid were investigated. An increase of the mobility of charge carriers in these solutions was found in comparison with so... see more

Methylene blue (MB) is a dye in wastewater from textile industries that pollutes the water environment. Reduction of its content is necessary for protecting humans and the surrounding environment. This study fabricated chitosan/Fe3O4 nanocomposite through... see more

In this research, silver nanoparticles (AgNP) impregnated on natural magnetic material/chitosan composite (NMP/Chi) have been conducted with different AgNP concentrations (0.5, 1.0, 1.5 mM). Their antibacterial activity was examined against Escherichia co... see more

Silver nanoparticles have been developed in many applications because of their optical and reactivity properties. One of the disadvantages of silver nanoparticles is their low level of stability because their surface is easy to aggregate. It is necessary ... see more

Colloidal gold nanoparticles prepared by employing chitosan as the stabilizer in solvent of methanol-acetic acid solution were stable for months without precipitation. The mole ratio of chitosan-gold ions of 5:1 - 30:1 gave dispersed and fine gold particl... see more

Chitosan-stabilized gold nanoparticles were synthesized in aqueous formic acid, citric, or acetic acid with and without chitosan as the stabilizer. Refluxing in methanol, addition of hydrazine or sodium borohydride, photo-irradiation were employed as the ... see more

The application of nanotechnology for the treatment, diagnosis, monitoring, and control of biological systems has recently been determined by the National of Health (NIH) as nanomedicine. The strategy of Nanoparticle delivery plays a significant impact on... see more

Curcumin or diferuloylmethane as a naturally derived substance from  herbal remedy and a good potential to posses many diseases are widely reported.  However, Curcumin's poor aqueous solubility, low bioavalaibilty, and rapid degradation limiting... see more
