title: Investigation of silver nanoparticles synthesis using aminated β-cyclodextrin.
abstract: Aminated β-cyclodextrin was prepared through the reaction of 2-chloroethylamine with β-cyclodextrin. The preparation was carried out under different conditions (time, temperature, concentration of NaOH, and concentration of 2-chloroethylamine). The aminated β-cyclodextrin was used as reducing and stabilizing agent for the preparation of silver nanoparticles from AgNO₃. Factors (pH, temperature, time, extent of amination and concentration of aminated β-cyclodextrin) affecting the preparation of silver nanoparticles were studied. The prepared silver nanoparticles were evaluated by UV-visible spectral analysis and transmission electron microscopy (TEM). The results obtained indicate that the optimum conditions for preparation of silver nanoparticles with size ranged from 1 to 9 nm could be produced using 0.6 g β-cyclodextrin derivative, 0.1 M AgNO₃ at pH 12, 70 °C for 20 min.
