Abstract

See full text

Disclosed herein is a micro particle with a diameter of 10-100 microns, wherein the micro particle is coated with silver nanoparticles; and wherein the nanoparticles are coated with a polysaccharide; and wherein the polysaccharide coating is digestible by bacteria. Also, disclosed is a method of making silver nanoparticles using an ascorbic acid derivative or an alpha-hydroxyl carboxylic acid derivative as a reducing agent. The silver nanoparticles may be coated onto micro particles, embedded in hydrogel particles or coated with polysaccharide. The silver nanoparticles may be used in a wound dressing, a bandage, a fungal treatment product, a deodorant, a floss product, a toothpick, a dietary supplement, dental X-ray, a mouthwash, a toothpaste, acne or wound treatment product, skin scrub, and skin defoliate agent.
