Abstract
This invention relates to an improved process for the preparation of stable suspension of nano silver particles having antibacterial activity, comprising the steps of: (i). Preparing a glucose solution and a silver salt solution in water separately wherein silver salt is selected from Silver Sulphate, Silver Accetate and Silver Nitrate; (ii) Mixing the two solutions, as prepared in step (i), and stirring the mixture for 5 to 10 minutes; (iii) Preparing a solution of surfactant in water and adding the solution, to the solution obtained in step (ii) and stirred slowly for 1 - 5 minutes; (iv) Adding the basic reagent diethyl amine to the solution obtained in step (iii) if silver sulphate or silver acetate is used, or adding the basic reagent Sodium carbonate to the solution obtained in step (iii) if silver salt, as mentioned in step(i), is used and (v) Adding anti foaming agent to the suspension obtained in step (iii).
