Investigation of silver nanoparticles synthesis using aminated β-cyclodextrin

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.
