This study provides a novel insight for enzymatic synthesis method of silver nanoparticles using purple acid phosphatase, isolated from Limonia acidissima (wood apple) as a new source and used in the synthesis of silver nanoparticles. Stable silver nanoparticles were produced by sonochemical method using apoenzyme as a stabilising and capping agent and were characterised by various physicochemical techniques like UV-Visible spectroscopy, Fourier-transform infrared, X-ray diffraction and transmission electron microscopy. X-ray study shows that nanoparticles are composed of silver and silver oxide. The synthesised nanoparticles exhibited excellent antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.</p>10agreen synthesis10aLimonia acidissima10apurple acid phosphatase10asilver nanoparticles1 aPawar, Omkar1 aDeshpande, Neelima1 aDagade, Sharda1 aWaghmode, Shobha1 aJoshi, Preeti, Nigam  uhttps://library.ncl.res.in/content/green-synthesis-silver-nanoparticles-purple-acid-phosphatase-apoenzyme-isolated-new-source-001853nas a2200229   4500008004100000022001400041245010500055210006900160260000800229300001200237490000700249520105300256653001601309653003501325653002901360653002001389653002201409100002501431700002201456700002101478856012401499       2018                        eng d  a1066-785700aSynthesis of ecofriendly fluorescent carbon dots and their biomedical and environmental applications0 aSynthesis of ecofriendly fluorescent carbon dots and their biome  cJAN  a672-6800 v333 a<p>Green Synthesis of nanoparticles is an emerging field with enormous advantages over conventional synthesis methods. Herein we have reported a green method for the preparation of water soluble polydisperse carbon dots (c-dots) from Cocos nucifera frond pinnae by a modified version of the `single step hydrothermal carbonization'. C-dots having blue emission were obtained with this method and we further evaluated the effect of metal ions interactions on c-dots, as a sharp decrease in photoluminescence was observed. The synthesized c-dots were found bioactive against B.subtilis, M. smegmatis and S. aureus as determined by the well diffusion assay. We also explored nanotheranostic applications of c-dots as biosensor matrix in DNA hybridization sensor for pancreatic cancer and in bioimaging of cancer cells. This study demonstrated that c-dots can be explored for numerous biomedical and environmental applications in a variety of fields owing to the cost effective synthesis, biocompatibility and excellent physico-chemical properties.</p>10aCarbon dots10adifferential pulse voltammetry10aDNA hybridization sensor10agreen synthesis10aPancreatic Cancer1 aJoshi, Preeti, Nigam1 aMathias, Anjelica1 aMishra, Abhishek  uhttps://library.ncl.res.in/content/synthesis-ecofriendly-fluorescent-carbon-dots-and-their-biomedical-and-environmental
