Curcumin as a novel reducing and stabilizing agent for the green synthesis of metallic nanoparticles

Abstract

This review expands for the first time the development of curcumin as reducing and stabilizing agent. Curcumin is widely used in food industries, cosmetic domain and the biomedical field. The combination of green synthesis and curcumin to produce nanoparticles has been effective as the amount of toxic waste is highly reduced. Starting with a general introduction about nanoparticles synthesis and curcumin, the use of curcumin as a principal reducing agent and stabilizing compounds in the production of nanoparticles is developed. Consecutively, the preparation of different nanoparticles as gold nanoparticles (Au NPs), silver nanoparticles (Ag NPs), copper nanoparticles (Cu NPs), iron nanoparticles (Fe NPs), and manganese and manganese oxide nanoparticles (Mn NPs, MnO NPs) using curcumin is investigated and elaborated. The mechanism of interaction of curcumin with the different metal has also been developed. A concluding section summarizes the advantages of using curcumin as reducing/ stabilizing agent in nanoparticles formation and their analytical applications.

Curcumin assisted green synthesis of silver and zinc oxide nanostructures and their antibacterial activity against some clinical pathogenic multi-drug resistant bacteria

“…Green synthesis of silver nanoparticles in the presence of curcumin extract was characterized by a change in colour, from the orange colour of curcumin extract to yellowish-brown colour, indicating the formation of Cur-AgNPs. 41,65 The colour change was attributed to the nucleation of Ag NPs as the interaction between Ag + ions and the –OH − groups exists in flavonoids and Terpenoids that play a vital role in the synthesis of Ag NPs. 38 Later on, with increasing the reaction time, the colour changes to brownish-yellow colour due to the maturation of Ag nanoclusters and, thereby, the formation of AgNPs.…”

Recent Developments and Applications of Nanosystems in the Preservation of Meat and Meat Products

“…The so-called “green” metallic nanoparticle preparation methods offer ways to reduce pollution and help minimize undesirable effects of these NP [ 40 , 41 ]. Dissolvents such as ethanol, hexane, toluene, DMF (N, N-dimethylformamide), and diethyl ether have harmful safety, health, and environmental effects [ 42 ].…”

Preparing Copper Nanoparticles and Flexible Copper Conductive Sheets

“…Chemical reduction methods are bottom-up, involving oxidation reduction reactions that handle the precursor in the form of an atomic ion with a reducing agent in a suitable solvent [ 9 , 10 ]. The created metallic nanoparticles have various particle size distributions and stability levels based on conditions such as the reducing agent concentration, reduction potential, temperature, pH value, and stabilizer [ 11 , 12 , 13 ]. Chemical reduction methods are most commonly used for synthesizing various types of nanoparticles because they do not require special equipment and are relatively easy to conduct [ 14 , 15 , 16 , 17 ].…”
