ABSTRACT = {In our previous study, silver nanoparticles were prepared using AgNO<sub>3</sub> and carboxymethyl chitosan (CMCS)
which is commercially available with solar irradiation. In this study, the efficacy and safety of silver nanoparticles
prepared by this method were evaluated for healing wounds in rats with diabetes. We also attempted to determine
the underlying mechanism and influencing factors of the silver nanomaterial preparation method. Compared with
growth factors, silver nanoparticles exhibit better healing effects for rats with diabetes. No remnant silver ions
were detected in the major organs of these rats after the application of silver nanoparticles. Silver nanoparticles
prepared using CMCS are less toxic than those prepared from the conventional method, promote the proliferation
of skin fibroblasts, and are promising as a topical medication for infected wounds. An obvious breakage process of
the particles is observed during the growth of nanocrystalline silver in CMCS. In this study, we also attempted to
determine whether this method is suitable for synthesizing silver nanoparticles using N-trimethyl chitosan chloride and sodium alginate were used in this particular experiment. The characteristic UV-vis absorbance peak of
silver nanoparticles was found only in the reaction mixture containing N-trimethyl chitosan chloride. Our study
demonstrates that free radicals are the key factor in this silver nanoparticle preparation method.},
