Biogenic Nanoparticle Synthesis Using Marine Alga Schizochytrium sp.

Abstract

Nanotechnology is one of the most promising science and technology discipline that targets to bring new solutions for many applications in biotechnology, biomedical, energy and cosmetic industry by improving particles and devices scale of nanometers. Various sized and shaped nanoparticles can be synthesized by several methods. Up to now, scientists prefer physical and chemical fabrication of nanoparticles. But, these methods contain use of toxic, expensive and non-environmentalist solvents, reducing and stabilising agents. For a sustainable science, there is a necessity development of more eco-friendly, cost-effective and trustable alternative processes. In this context, using biological sources as reaction agent, have a strong potential. Plants, bacteria, fungi are essential biological sources for transformation of metals to nanoparticles. Many researchers focus on fungi and bacteriological potential in nanofabrication whereas algae are highly intriguing biological systems in nanotechnological approach. Some of cyanobacteria and algae have previously been used to synthesize intracellular or extracellular metal nanoparticles. Most of the research concentrate especially on gold and silver nanoparticle production from algae. In this work; bioreduction of silver, zinc and iron metals have been investigated using culture supernatant of marine algae Schizochytrium sp. For characterization of nanoparticles, UV visible spectroscopy, zeta sizer were used. Nanoparticle size was determined by zeta sizer and particles' surface plasmon resonance band detected by UV-Visible Spectroscopy.
