A novel and easy method—electric spark discharge system (ESDS) for colloidal silver (CS) production has been successfully developed. ESDS-CS without any surfactants or stabilizers are characterized as a stable colloid and can maintained in a stable suspension in sealed glass vials in ambient condition for at least one and half years.
