Toward a Better Understanding of Metal Nanoparticles, a Novel Strategy from Eucalyptus Plants

Abstract

Nanotechnology is a promising tool that has opened the doors of improvement to the quality of human’s lives through its potential in numerous technological aspects. Green chemistry of nanoscale materials (1–100 nm) is as an effective and sustainable strategy to manufacture homogeneous nanoparticles (NPs) with unique properties, thus making the synthesis of green NPs, especially metal nanoparticles (MNPs), the scientist’s core theme. Researchers have tested different organisms to manufacture MNPs and the results of experiments confirmed that plants tend to be the ideal candidate amongst all entities and are suitable to synthesize a wide variety of MNPs. Natural and cultivated Eucalyptus forests are among woody plants used for landscape beautification and as forest products. The present review has been written to reflect the efficacious role of Eucalyptus in the synthesis of MNPs. To better understand this, the route of extracting MNPs from plants, in general, and Eucalyptus, in particular, are discussed. Furthermore, the crucial factors influencing the process of MNP synthesis from Eucalyptus as well as their characterization and recent applications are highlighted. Information gathered in this review is useful to build a basis for new prospective research ideas on how to exploit this woody species in the production of MNPs. Nevertheless, there is a necessity to feed the scientific field with further investigations on wider applications of Eucalyptus-derived MNPs.

Environmental Remediation Promoted by Silver Nanoparticles Biosynthesized by Eucalyptus Leaves Extract

“…XRD analysis is a popular technique used to investigate the crystal structure and size of MNP [29]. The XRD patterns of AgNP 50 • C-1:2 were recorded from 20 • to 80 • as shown in Fig.…”

“…The features of the MNP generated are known to be influenced by the type of plant extract employed because different plant extracts contain varying quantities of organic reducing agents [28]. Eucalyptus, a genus in the Myrtaceae family, are the world's largest cultivated and natural hardwood flora [29]. Eucalyptus leaves extract has a high content of polyphenols, polyphenols, flavonoids, tannins terpenoids and monoterpenes that contribute to strong reducing ability [30].…”

Green Synthesis of Silver Nanoparticles Coated by Water Soluble Chitosan and Its Potency as Non-Alcoholic Hand Sanitizer Formulation

“…Characterization of silver nanoparticles with a UV-Vis spectrophotometer was conducted to observe the characteristic absorption peaks or surface plasmon resonance of the silver particles in the sample using distilled water as a blank solution. Sawalha et al [45] and Razy et al [46] reported that the UV-Vis instrument is an essential instrument to obtain information related to the SPR peaks in silver nanoparticle formation. To complement UV-Vis, nanoparticles can be characterized by EDX, XRD, and FTIR.…”

Fabrication of anti-bacterial cotton bandage using biologically synthesized nanoparticles for medical applications

“…This issue can be overcome by employing biological agents, such as bacteria, fungi, algae, actinomycetes, and plants for the synthesis of metal nanoparticles (John et al 2021 ; Koul et al 2021 ; Chugh et al 2021 ; Rai et al 2021 ; Dikshit et al 2021 ). Recently, the use of plant extracts for nanoparticle synthesis has received much attention due to the rich diversity of phytochemicals, availability in bulk quantities, and simplicity (Balciunaitiene et al 2021 ; Amjad et al 2021 ; Gaddam et al 2021 ; Aboyewa et al 2021 ; Selvakesavan and Franklin 2021 ; Sawalha et al 2021 ; Rajagopal et al 2021 ).…”
