Abstract
The importance of studies on developing new materials with improved properties; such as anti bacterial activity, biocompatibility and anticancer properties are increasing gradually every day. Stronger mechanical properties can be obtained by adding a small amount of inorganic nanofiller into the organic matrix. Homogeneous nanodispersion of inorganic phase in nanodimension into the organic matrix is very important in developing new biomaterials with advanced features. In this study a natural biodegradable and nontoxic biopolymer and natural inorganic nano filler are used to develop a new nanobiomaterial with antibacterial activity. In order to obtain unique properties and impact we should understand and control the structure at the molecular level. One of the most important factors here is to achieve the nano dispersion of zero valent metal in the biopolymer matrix. The objective of this study is preparation of zero valent iron nanoparticles by chemical methods and then mixing sub-components in nanoscale to create unique antibacterial property. When exposed to oxygen and water, iron oxidizes in the acidic environment. The key point here is to disperse adequate amount of iron which is small enough in the biopolymer matrix. This will make hyperoxides to create hydroxy radicals. Superoxide-dependent formation of hydroxyl radicals are expected to damage DNA, proteins, lipids, and other cellular components. In our study the size of iron nanoparticles is small enough to penetrate into the bacteria. By manipulating dispersion conditions and iron concentration one could control the size of nano iron particles to develop the biomaterial as an anti cancer agent.
