Publication date: Available online 20 November 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Chunyang Fang, Ziping Ma, Liqiu Chen, Hongjie Li, Chao Jiang, Wenbin ZhangAbstractIn the present work, a facile biosynthetic approach for the synthesis of AuNPs using bark extract of Juglans regia (J. regia) is reported. Ultra-violet visible (UV–vis) absorption spectroscopic studies exhibited and narrow SPR absorption band at 540 nm, represented the isotropy in particle size. The transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis, confirmed the fabrication of spherical and crystalline nanoparticles of average size of about 14 nm. Also, typical characteristic selected area electron diffraction (SAED) pattern showed the crystalline nature o...
