Abstract

Synthesis of silver nanoparticles can be carried out using bioreductors which are natural reducing agents from natural materials containing antioxidant compounds or polyols which can reduce silver due to the nucleophilic nature of phenolic compounds in plant secondary metabolites. The use of bioreductors in the manufacture of nanoparticles can reduce the adverse effects and hazardous waste generated due to reduced adsorption of the toxic properties of the solvent used. The content of organic compounds in bioreductors can be utilized, for example secondary metabolites such as terpenoids, flavonoids and tannins which act as antioxidants and capping agents, where Ag+ ions in AgNO3 can be reduced into silver nanoparticles, so bioreductors can replace the role of synthetic reducing agents. Based on the literature used, several plants whose extracts can be used as bioreductors, namely gambier, gotu kola leaves, water hyacinth leaves, bilimbi leaves, cempedak bark and bay leaves using variations in the concentration and composition of the AgNO3 solution. The results of silver nanoparticles were synthesized using bioreductors, namely various nano-sized particles and based on UV-Vis spectrophotometry data, silver nanoparticles appeared at wavelengths between 410 - 450 nm. Keywords: Secondary metabolites, Bioreductors, Silver Nanoparticles

Abstract

Green synthesis is an eco-friendly approach that provides a viable alternative to traditional physical and chemical methods for the production of nanoparticles. This technique employs non-toxic and safe materials, such as plants, microorganisms, algae, bacteria, yeast, and fungi, to generate stable and less toxic nanoparticles. Citrus sinensis, commonly known as sweet orange, is a plant that contains various active compounds. These bioactive compounds can be extracted and used as bioreductants in green synthesis of nanoparticles. This mini review aimed to provide an overview of the current state of research on the utilization of Citrus sinensis as a bioreductant in the production of nanoparticles. A systematic search strategy was employed to identify research articles that met the criteria of discussing green synthesis of nanoparticles with Citrus sinensis as a bioreductant. The nanoparticles produced using Citrus sinensis extract can be either metal nanoparticles or metal oxide nanoparticles. The review highlights the distribution of nanoparticles produced with Citrus sinensis extract, their applications, and the extraction process of Citrus sinensis commonly employed in green synthesis of nanoparticles. Hopefully this review serves as a useful reference for researchers and practitioners who are interested in employing the Citrus sinensis plant as a bioreductant in the green synthesis of nanoparticles.
