Eucalyptus globulus Mediated Green Synthesis of Environmentally Benign Metal Based Nanostructures: A Review

Abstract

The progress in nanotechnology has effectively tackled and overcome numerous global issues, including climate change, environmental contamination, and various lethal diseases. The nanostructures being a vital part of nanotechnology have been synthesized employing different physicochemical methods. However, these methods are expensive, polluting, eco-unfriendly, and produce toxic byproducts. Green chemistry having exceptional attributes, such as cost-effectiveness, non-toxicity, higher stability, environment friendliness, ability to control size and shape, and superior performance, has emerged as a promising alternative to address the drawbacks of conventional approaches. Plant extracts are recognized as the best option for the biosynthesis of nanoparticles due to adherence to the environmentally benign route and sustainability agenda 2030 of the United Nations. In recent decades, phytosynthesized nanoparticles have gained much attention for different scientific applications. Eucalyptus globulus (blue gum) is an evergreen plant belonging to the family Myrtaceae, which is the targeted point of this review article. Herein, we mainly focus on the fabrication of nanoparticles, such as zinc oxide, copper oxide, iron oxide, lanthanum oxide, titanium dioxide, magnesium oxide, lead oxide, nickel oxide, gold, silver, and zirconium oxide, by utilizing Eucalyptus globulus extract and its essential oils. This review article aims to provide an overview of the synthesis, characterization results, and biomedical applications of nanoparticles synthesized using Eucalyptus globulus. The present study will be a better contribution to the readers and the students of environmental research.

Amomum subulatum Fruit Extract Mediated Green Synthesis of Silver and Copper Oxide Nanoparticles: Synthesis, Characterization, Antibacterial and Anticancer Activities

“…Numerous studies have utilized extracts from various plant species for the synthesis of AgNPs and CuONPs and assessed their antibacterial, antioxidant, and anticancer activities. Some examples include the use of extracts from Sphaeranthus indices [20], Acalypha indica [21], Salvia spinosa [22], Pinus roxburghii [23], Camellia sinensis [24], Eucalyptus globulus [25], Azadirachta indica [26], Sida acuta [27]. These studies demonstrated the potential of plant-based synthesis of nanoparticles and highlighted their antioxidant, antibacterial, and anticancer properties.…”

Photoelectrocatalytic Detection and Degradation Studies of a Hazardous Textile Dye Safranin T

“…It finds usage in transparent conductors, photocatalysis, chemical sensors, optical, and piezoelectric devices. The applications of ZnO have a strong dependence on its size, aspect ratio, and morphology [41,42]. Numerous investigations have been conducted to modify the attributes of ZnO NPs to make them appropriate for various applications.…”
