Abstract
Green protocols for the synthesis of nanoparticles have been attracting a lot of attention because they are eco-friendly, rapid, and cost-effective. Nickel and nickel oxide nanoparticles have been synthesized by green routes and characterized for impact of green chemistry on the properties and biological effects of nanoparticles in the last five years. Green synthesis, properties, and applications of nickel and nickel oxide nanoparticles have been reported in the literature. This review summarizes the synthesis of nickel and nickel oxide nanoparticles using different biological systems. This review also provides comparative overview of influence of chemical synthesis and green synthesis on structural properties of nickel and nickel oxide nanoparticles and their biological behavior. It concludes that green methods for synthesis of nickel and nickel oxide nanoparticles are better than chemical synthetic methods.
Highlights
Nanoparticles (NPs) are cluster of atoms having at least one dimension in the size range of 1–100 nm
We present a comparative overview of influence of chemical synthesis and green synthesis on the Ni and Nickel Oxide (NiO) NPs structural properties and biological properties
Their scanning electron microscopy (SEM) images exhibited that NPs were capped by organic biomolecule layer which is derived from leaf extract of Aegle marmelos Correa (AmC) having surface functional –OH groups that take part in bioreduction of Ni(II) ions into Ni(0) NPs, besides acting as stabilizing and capping agent
Summary
Nanoparticles (NPs) are cluster of atoms having at least one dimension in the size range of 1–100 nm Owing to their unique optical, magnetic, catalytic, and electrical properties, they have potential applications in various fields [1]. Biological synthesis provides an environmental friendly, simple, inexpensive approach for synthesizing NPs with an added advantage of stabilizing the formed NPs as plant secondary metabolites besides acting as synthetic agents act as capping agent. NPs synthesized by using green chemistry have no or low cytotoxicity as compared to chemically synthesized NPs which makes them efficient carrier of drugs for in vivo drug delivery applications [19]. International Journal of Analytical Chemistry parameters on the structural properties of formed Ni NPs. We present a comparative overview of influence of chemical synthesis and green synthesis on the Ni and NiO NPs structural properties and biological properties
