: From last two decades, extensive research is going on metal and metal oxide nanoparticles and their application in field of medical, cosmetic, catalyst, packaging, photonics, agriculture and electronics. However, these nanoparticles show toxicity to the environmental, human and animal health. The toxicity effects of nanoparticles are mainly due to its size which can be easily pass through physiological barriers and the other due to the synthesis procedure. The toxicity due to their size cannot be avoided but toxicity due to synthesis process can be nullified by adopting biosynthesis process. Bacteria, fungus, fish scales, plant extracts and algae are used to synthesize metal and metal-oxide nanoparticles such as silver, gold, iron-oxide, zinc-oxide, zirconia, etc. From last a few year researchers are working on plant extracts synthesis methods to produce stable, cost-effective and economical these nanoparticles. In this review, we focus on biosynthesis of nanoparticles using different parts of plant extracts. The review contains summary of selected papers from 2018 – 20 with detail description of process of synthesis, mechanism, characterization and their application in various fields of biosynthesized metal and metal oxide nanoparticles.

The introduction of inorganic and organic pollutants into water bodies has become a serious issue globally. The waste streams released from the textile, plastic, leather, paper, pharmaceutical, and food industries introduce different natural and synthetic dyes into the aquatic system. Nanomaterials play a significant role in the photocatalytic degradation of dyes present in wastewater. Inorganic metal oxide nanoparticles have many improved physical and chemical properties and attracted much attention in photocatalytic activities. Dyes have been released in our aquatic bodies due to many anthropogenic activities and caused life-threatening problems. Various conventional methods were reported to remove dyes from water and wastewater; the photocatalytic method is one of the efficient and cost-effective. The present review article includes detailed information on photocatalysis, the potential of metal oxide and their composite materials as photocatalysts in the degradation of toxic dyes, and some common synthetic and characterization methods used for metal oxide-based nanoparticles.

Zinc oxide is of significant importance for many industries due to its versatile properties, which have been enhanced with the production of this material in the nanoscale. Recent interest in the preparation of metal oxide nanoparticles using biological approaches has been reported in the literature. This technique known as “green synthesis” is an environmentally benign process than conventional methods like physical and chemical synthesis methods. Zinc oxide nanoparticles (ZnO-NPs) have been successfully obtained by green synthesis using different biological substrates like chitosan. Chitosan is biocompatible, biodegradable polymer having exclusive physical and chemical properties. Chitosan/metal oxide nanocomposite is a promising nanomaterial with enhanced properties for multiple functionalities. Therefore, this review discusses favorable approach in the formation of cross-linked Chitosan/ZnO nanocomposites attracting significant attention in various fields such biomedical due to their unique biodegradable, biocompatible, non-toxic nature. The use of biological sources, fabrication of green synthesized ZnO nanoparticles and its applications is briefly discussed. Overall, this review is a comprehensive study for the synthesis of ZnO-NPs using biological sources counting on their features and applications.

Increased request for metal and metal oxide nanoparticles nanoparticles has led to their large-scale production using high-energy methods with various toxic solvents. This cause environmental contamination, thus eco-friendly “green” synthesis methods has become necessary. An alternative way to synthesize metal nanoparticles includes using bioresources, such as plants and plant products, bacteria, fungi, yeast, algae, etc. “Green” synthesis has low toxicity, is safe for human health and environment compared to other methods, meaning it is the best approach for obtaining metal and metal oxide nanoparticles. This review reveals 12 principles of “green” chemistry and examples of biological components suitable for “green” synthesis, as well as modern scientific research of eco-friendly synthesis methods of magnetic and metal nanoparticles. Particularly, using extracts of green tea, fruits, roots, leaves, etc., to obtain Fe3O4 NPs. The various precursors as egg white (albumen), leaf and fruit extracts, etc., can be used for the „green” synthesis of spinel magnetic NPs. “Green” nanoparticles are being widely used as antimicrobials, photocatalysts and adsorbents. “Green” magnetic nanoparticles demonstrate low toxicity and high biocompatibility, which allows for their biomedical application, especially for targeted drug delivery, contrast imaging and magnetic hyperthermia applications. The synthesis of silver, gold, platinum and palladium nanoparticles using extracts from fungi, red algae, fruits, etc., has been described.

Abstract Metal oxide nanoparticles (NPs) have found a variety of applications in numerous industrial, medical, and environmental fields s, attributable to recent advances in the nanotechnology field. Titanium dioxide nanoparticles (TiO2-NPs) have gained importance as metal oxide NPs due to their potential in various fields, particularly nanomedicine and other biomedicine fields. Several studies have confirmed that NPs produced via the biosynthesis route using natural resources have significant advantages such as fewer toxic contaminants, less subsequent complex chemical synthesis, environmental friendliness, cost-effectiveness, and stability when compared to NPs produced by conventional methods, and its production with controlled shapes and sizes. Therefore, considerable effort is being expended to implement biological synthesis methods with these proven advantages. TiO2-NPs can be made using a variety of biological, chemical, and physical methods. Physicochemical methods are costly, emit high levels of toxic chemicals into the atmosphere, and consume a lot of energy. On the other hand, the biological approach is an environmentally safe, cost-effective, dependable, convenient, and easy way to synthesize TiO2-NPs. In this review, the bio-mediated synthesis, as well as various biomedical applications of TiO2-NPs, were discussed.
