Methods for Green Synthesis of Metallic Nanoparticles Using Plant Extracts and their Biological Applications - A Review

Abstract

Nanotechnology, a fast-developing branch of science, is gaining extensive popularity among researchers simply because of the multitude of applications it can offer. In recent years, biological synthesis has been widely used instead of physical and chemical synthesis methods, which often produce toxic products. These synthesis methods are now being commonly adapted to discover new applications of nanoparticles synthesized using plant extracts. In this review, we elucidate the various ways by which nanoparticles can be biologically synthesized. We further discuss the applications of these nanoparticles.

Catalytic Reduction of 4-Nitrophenol and Methylene Blue with Silver Nanoparticles Decorated with Drymoglossum piloselloides Extract

“…The focus is on silver nanoparticle synthesis processes that reduce the use of harmful chemicals and use more efficient production methods, resulting in products with minimal environmental impact. One of the approaches used by researchers is the use of plant extracts in a green synthesis approach [12][13][14]. Several types of plants have been reported to have the potential to be used in the synthesis of silver nanoparticles, such as Camelia sinensis [15],…”

Biosynthesis of TiO2 nano particles by using Rosemary (Rosmarinus officinalis) leaf extracts and its application for crystal dye degradation under sunlight

“…Additionally, TiO 2 shows not only antifouling as well as anti-bacterial characteristics but also virtuous photo-catalytic activities [ 34 ]. Due to its many welfares, such as great photo-catalytic ability, high oxidizing power, low toxicity and biocompatibility, excellent chemical stability, and ease of accessibility, TiO 2 is one of the best materials for photo-catalytic processes [ 35 – 37 ].…”
