Introduction

Silver nanoparticles have been used as colloidal silver for more than 100 years. Historically, colloidal silver containing silver with different concentrations and particle sizes has been widely used to treat wounds and infections. Penetration of silver into the bacteria cells induces a high degree of structural and morphological changes which lead to the death of that cell. Silver nanoparticles can prevent the growth or adhesion of bacteria onto the surface. This can be especially useful in the operation room, where all surfaces in contact with the patient’s body should be sterilized. In addition, silver nanoparticles can be incorporated into a variety of surfaces, such as metal, plastic, and glass. This product has been introduced into the market with two different concentrations:

• Disinfectant containing 100 ppm silver nanoparticles
• Disinfectant containing 2000 ppm silver nanoparticles

Introduction

Filter plus is a masterpiece filter using sophisticated technology containing silver nanoparticles for significant reduction of harmful substances in shisha smoke and bacteria transferred from the shisha hose. Disposable oral hookah filters cause a remarkable decrease in harmful hookah smokes.

This filter with its Nanoparticles can absorb and separate particles existing in hookah smoke. So far, more than 4,000 chemicals have been found in tobacco that contains compounds such as nicotine, free radicals, harmful gases, volatile organic compounds, aldehydes, aromatics, etc. Most of these compounds cause problems such as cancer and vascular heart disease.
