This paper is aimed at reviewing the application of biological extracts from plants, fungi and bacteria in the synthesis of metal/metal oxide nanoparticles with reference to Ag and TiO2 nanoparticles as a case study. The procedures for the extraction of the biological extracts as well as the chemical instrumentation analysis of the extracts and metal/metal oxide nanoparticles were explained in this review. It was reported that standard chemical test confirms the presence of tannins, alkanoids, flavonoids and terpenoids in various plant extracts, while FTIR characterization of various biological extracts confirms the presence of organic compounds as a capping and reducing agents in the biosynthetic process for the preparation of the nanoparticles. The use of other instrumental techniques such as FESEM, XRD, SEM, EDX, TEM and UV-Visible spectroscopy in the characterization of biosynthesized metal/metal oxide nanoparticles were also explained in this review.

Clean Manufacturing

Today there is a growing need to develop reliable, sustainable, and ecofriendly protocols for manufacturing a wide range of metal and metal oxide nanoparticles. The biogenic synthesis of nanoparticles via nanobiotechnology based techniques has the potential to deliver clean manufacturing technologies. These new clean technologies can significantly reduce environmental contamination and decease the hazards to human health resulting from the use of toxic chemicals and solvents currently used in conventional industrial fabrication processes. The largely unexplored marine environment that covers approximately 70% of the earth’s surface is home to many naturally occurring and renewable marine plants. The present review summarizes current research into the biogenic synthesis of metal and metal oxide nanoparticles via marine algae (commonly known as seaweeds) and seagrasses. Both groups of marine plants contain a wide variety of biologically active compounds and secondary metabolites that enables these plants to act as biological factories for the manufacture of metal and metal oxide nanoparticles.
