Plant-Mediated Synthesis of Iron Oxide Nanoparticles and Evaluation of the Antimicrobial Activity: A Review

Abstract

: In this review, we examine ‘greener’ routes to nanoparticles of iron oxides, in the recent years; nanotechnology has emerged as a state-of-the-art and cutting edge technology with multifarious applications in a wide array of fields. Natural products or extracted from natural products. Such as different plant extracts, have been used as reductants, and as capping agents during synthesis. A very easy, efficient and environment-friendly protocol was developed to synthesize green nanoparticles (NPs) with an aqueous extract of various plant, phenolic compounds extracted from plants play a major role as a non-toxic reducing and capping agents for nanoparticle. Nanoparticles and their compounds are known to exert a strong inhibitory and microbial activity on bacteria, viruses, and fungi. In today's world, because of the epidemic of infectious diseases caused by different pathogenic bacteria and the development of antibiotic resistance. Green synthesis, characterization, and application of nanoparticles (NPs) are becoming an important challenge in nanotechnology. Green synthesis of nanoparticles is made in large quantities worldwide for a wide range of applications. This technique is very safe and environmentally friendly.

Preparation, Physicochemical Assessment and the Antimicrobial Action of Hydroxyapatite–Gelatin/Curcumin Nanofibrous Composites as a Dental Biomaterial

“…Nanomaterials have the ability to disrupt cell membrane functions by binding to the surface of cell membranes with a high affinity. This effect is more predominant in smaller nanoparticles, owing to their larger surface space [ 49 , 50 , 51 ]. The interaction between the membrane and nanomaterials also leads to local pores in the membrane and harms the bacteria due to the passing of nanoparticles into the bacteria and the interaction of bacteria‘s proteins with DNA [ 52 ].…”

Green Synthesized of Ag/Ag2O Nanoparticles Using Aqueous Leaves Extracts of Phoenix dactylifera L. and Their Azo Dye Photodegradation

“…The leaves of Phoenix dactylifera L. were washed by distilled water, dried for 12 days in a shaded place at room temperature, and then crushed to obtain a fine powder. An amount of 10 g of powdered Phoenix dactylifera L. leaves were added to 100 mL of distilled water into a 250 mL glass beaker to prepare the extract [ 8 , 66 , 89 , 90 ]. The mixture was stirred stably at room temperature for 24 h. After that, the extract was filtered with filter paper (Whatman No: 42) and stored in a glass container at 4 °C for further use (maximum storage was 1 month in dark conditions).…”

Catalytic Activity for Dye Degradation and Characterization of Silver/Silver Oxide Nanoparticles Green Synthesized by Aqueous Leaves Extract of Phoenix Dactylifera L.

“…Green synthesis is a modern area of biotechnology that is economically and environmentally beneficial as an alternative to chemical and physical methods that contain part of the hazard to the environment. Because in this method, biologically safe, non-toxic, and environmentally friendly natural reagents 4 , Mentha pulegium L 5 , Artemisia 6 , Moringa Oleifera 7 , Phoenix dactylifera L 8 , and others are used in the biosynthesis of metal oxide nanoparticles 9,10 . The researchers used widely available plant extracts in nature in the green synthesis of metal oxide nanoparticles.…”
