A simple one-pot, completely green method has been developed that uses common sugars (sucrose and maltose) as reducing and capping agents to rapidly synthesize and stabilize metal nanoparticles. Even at relatively low temperatures (boiling water temperature) and short reaction times (30 minutes), nanoparticles in the size range of 6-60 nm can be synthesized without the need for microwave irradiation or any other intermediate steps.
Synthesis of Silver Nanoparticles
The silver nanoparticles were prepared using a simple wet-chemical method. A series of solutions were prepared by dissolving 5 g of sugar in 100 mL of water and boiling for a few minutes. Then, 2.5 mL of 10-2 M AgNO3 solution was added to it. Two different sugars, sucrose and maltose, were used separately as the reducing agents for nanoparticle synthesis. The mixture was kept vigorously boiling for 30 minutes under stirring. After some time (about 10 minutes for sucrose and 6 minutes for maltose), the solution turned pale yellow, indicating the formation of silver nanoparticles.

A simple, green method has been developed for the first time to synthesize superparamagnetic Fe3O4 nanoparticles using maltose as both the reducing agent and the surfactant.
Synthesis of Superparamagnetic Fe3O4 Nanoparticles Using Maltose
FeCl3·6H2O and maltose were added in an 8:7 molar ratio and dissolved in 25 mL of deionized water under vigorous stirring. The pH of the solution was then adjusted to around 10.5 by dropwise addition of 25% ammonia water. The mixture was kept vigorously stirred for about 30 minutes, then transferred to a stainless-steel high-pressure vessel (50 mL capacity) with a Teflon liner and crystallized at 180 °C for 48 hours. After naturally cooling to room temperature, the product was separated from the liquid phase by centrifugation and thoroughly washed three times with deionized water to remove any water-soluble organic byproducts. The final product was dried overnight at 50 °C, resulting in a fine blackish-brown powder.
