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...

In  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  X-ray  diffraction  (XRD)  and scanning  electron  microscopy  (SEM).  The  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human p...
