Plant-mediated synthesis of size-controllable Ni nanoparticles with alfalfa extract

Bio-inspired synthesis of metal nanomaterials and applications

“…44 As an alternative to size control, spherical Au NPs with different sizes and Au nanoplates with different edge lengths could be well fractionated to obtain monodisperse Au NPs through the two-step size-and shape-separation. 45,154,[194][195][196][197] Results showed that flavonoid and reducing sugar were the main reductive and protective components in C. Platycladi leaf and alfalfa extract to biosynthesize Au and Ni NPs,respectively. One of the focuses in the biosynthesis of metal NPs with plant extract is to understand the bioreductive mechanism that is very challenging due to complicated components in plant extract.…”

“…181 3.3.3 Elucidation of complicated bioreductive mechanism. 194,197 For the first time from the standpoint of statistics, Zhou et al 154 confirmed an electrostatic force or ionic bond-based interaction between the chloroauric ions and the involved bioconstituents, manifested the importance of flavonoid and reducing sugar to reduce metallic ions and illustrated a significant linear relationship between the anti-oxidant activity of the foliar broths and their capability to reduce Au(III) into Au(0). In an attempt to explore the mechanism, a research group in Xiamen University has conducted a comprehensive study on the identification of active components in some plant extracts.…”

Synthesis of ZnO micro-flowers assisted by a plant-mediated strategy

“…Biological methods (using microorganisms and plant materials) have gradually been established as simpler, more economical and greener methods to synthesize nanomaterials, with the potential to replace conventional methods. Plant‐based routes, compared with microorganisms, possess bioreducing or/and bio‐template components such as reducing sugars, flavonoids and proteins . Moreover, there is no need for the maintenance of cell cultures as in the case of microorganisms.…”

“…Plant-based routes, compared with microorganisms, possess bioreducing or/and bio-template components such as reducing sugars, flavonoids and proteins. 15,16 Moreover, there is no need for the maintenance of cell cultures as in the case of microorganisms. Reports of a few biological methods of producing ZnO materials can be found in literature.…”

Structure and magnetic properties of nickel nanoparticles prepared by selective leaching

“…Many papers describe preparation of Ni nanoparticles by reduction of aqueous solution of nickel salts alternatively with or without addition of alcohol or oil [2][3][4][5][6][7]. Some other paper describe production of nickel nanoparticles by micelles route [2,9], by utilization of plant extracts as reduction agent [3,8], by gamma irradiation [1] or laser ablation of solids in organic solutions [10]. This paper is focused on preparation of nickel nanoparticles by a selective leaching method.…”
