Sangiliyandi Gurunathan,Kalimuthu Kalishwaralal,Ramanathan Vaidyanathan,Deepak Venkataraman,Sureshbabu Ram Kumar Pandian,Jeyaraj Muniyandi,Nellaiah Hariharan,Soo Hyun Eom +7 more
TL;DR: The optimal conditions for maximum synthesis of silver nanoparticles (AgNPs) through reduction of Ag(+) ions by the culture supernatant of Escherichia coli are reported and it is demonstrated that particle size could be controlled by varying the parameters such as temperature, pH and concentration of AgNO(3).

Yang Xia,Zhen Xiao,Zhen Xiao,Xiao Dou,Hui Huang,Xianghong Lu,Rongjun Yan,Yongping Gan,Wenjun Zhu,Jiangping Tu,Zhang Wenkui,Xinyong Tao +11 more
TL;DR: Inspired by the natural microalgae with its special features, this work develops a green and facile biotemplating method to fabricate monodisperse MnO/C microspheres for lithium-ion batteries, which will extend the scope of biOTemplating synthesis for exploring other functional materials in various structure-dependent applications such as catalysis, gas sensing, and energy storage.
Journal ArticleDOI
Biosynthesis of silver, gold and bimetallic nanoparticles using the filamentous fungus Neurospora crassa.
TL;DR: The results obtained indicate that N. crassa can be a potential "nanofactory" for the synthesis of metallic NPs and the use of this organism will offer several advantages.

Journal ArticleDOI
Controlled nucleation for the regulation of the particle size in monodisperse gold suspensions
TL;DR: In this article, a series of monodisperse suspensions of the same chemical composition but of rather different particle sizes was used to study particle size dependent phenomena, such as Brownian motion, light scattering, sedimentation and electrophoresis of small particles.
Journal ArticleDOI
A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.
Journal ArticleDOI
Seeding of Colloidal Au Nanoparticle Solutions. 2. Improved Control of Particle Size and Shape
TL;DR: In this article, the surface of preformed 12-nm-diameter Au nanoparticles is reduced by boiling sodium citrate, producing particles highly uniform in size and shape, and a similar procedure, utilizing the reductant NH2OH at room temperature, produces two populations of particles.
