Synthesis of Metallic Nanoparticles by Diatoms and Chrysophytes - Prospects and Applications

Abstrakt

This chapter demonstrates a novel synthesis of metallic NPs and nanocomposites by biologically driven processes employing two diatom strains (Diadesmis gallica and Navicula atomus [Mayamaea atomus]) and a silica-scaled chrysophyte (Mallomonas kalinae). The chapter reports the fabrication of multi-purpose materials containing noble metal nanoparticles stabilized with cellular matrix on the biogenous silica scaffold.

This biosynthesis approach and usage of silica-based algal strains takes advantage of a simple three-in-one method for material preparation, where nanoparticle formation, stabilization and immobilization take place simultaneously.
