Abstract

Well-dispersed and uniform starch-stabilized silver nanoparticles (Ag-NPs) with a relatively narrow size distribution are prepared via green chemistry method by ultrasonic procedure. Solutions containing silver ions and starch in water gave starch-capped Ag-NPs, which could be integrated into medical applications such as using in antibacterial wound dressing. Eco-friendly materials as bio-organisms in plant extracts contain polysaccharides, which act as both reducing and capping agents forming stable and size-controlled Ag-NPs. The size of the Ag-NPs decreases with the ultrasonic time. Ultrafine spherical Ag-NPs with a mean particle size of about 8.5 nm have been synthesized under ultrasonic process. X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), UV–Vis spectroscopy, and transmission electron microscopy (TEM) are used to characterize the starch-stabilized Ag-NPs..
