Time and Size-dependent Biogenically Synthesized Nanoparticles Using Fungus Fusarium Oxysporum: A Review on their Preparation, Characterization and Biological Activities

Abstract

In recent time, green synthesis of Metal Nanoparticles (MNPs) is the latest developing technology and received exceptional interest because it is simple, eco-friendly, pollutant-free, nontoxic, and a low-cost approach. Green route of biogenic synthesis of metal nanoparticles via microbes (bacteria, fungi, virus, yeast, algae etc.) has the potential to deliver clean manufacturing technology. Fungi are in the great use for the synthesis of nanoparticles and are more advantageous as compared with other microorganisms in several ways. Fungi grow in the form of a group of mycelia, which helps them to withstand flow pressure and agitation and various other conditions to which microbes are subjected to in a bioreactor, used for large-scale production. This review has its major focus on fungus Fusarium oxysporum, which is capable of synthesizing a large number of different types of nanoparticles such as titanium, magnesium, platinum, silver, gold, zirconium, and strontium, titania and silica oxide and many more. Biogenically synthesized nanoparticles are characterized by different techniques and exhibited biological activity. The fungi with metabolic capabilities can effectively synthesize a large number of nanoparticles both extracellularly and intracellularly. The biologically synthesized nanoparticles have wide ranges of applications especially in agricultural and medicinal industries.
