Raspberry Extract as Both a Stabilizer and a Reducing Agent in Environmentally Friendly Process of Receiving Colloidal Silver

الملخص EN

An ecofriendly method of nanosilver obtaining has been studied.

The process involves the chemical reduction method carried out in aqueous environment.

Silver nitrate (V) was applied as a silver ions source.

Raspberry extract was used as a natural source of both reducing and stabilizing agents.

The total amount of phenolic compounds was determined by the Folin-Ciocalteu method.

Obtained nanoparticles were analyzed by the dynamic light scattering technique so as to determine the particles size and suspension stability which was characterized by an electrokinetic potential.

The results confirmed that the size of some nanoparticles was under 100 nm.
