Abstract: Plant mediated synthesis of metallic nanoparticles is an increasing commercial demand due to the wide applicability in various areas such as electronics, catalysis, chemistry, energy, cosmetics and medicine. In the present investigation, synthesis of gold nanoparticles is done by using fruit extracts of Ananas comosus (L.). Nanoparticles were characterized by using UV visible absorption spectra. Their morphology, elemental composition and crystalline phase were determined by scanning electron microscopy, energy dispersive X-ray spectroscopy and selected area electron diffraction. FT-IR analysis was used to confirm the presence of gold nanoparticles in the extracts. The synthesized gold nanoparticles were generally found to be effective as antimicrobial agents against some important human pathogens like E.coli and Streptobacillus sp. which are affecting and cause diseases like food poisoning and rat-bite fever to human beings respectively.

TL;DR: In this article, a set of 12 principles consisting of known concepts (i.e., reduction in the use of reagents and energy, and elimination of waste, risk, and hazard) together with some new ideas (e.g., the useof natural reagents) are proposed for the future of GAC.
Abstract: The current rapid development of green analytical chemistry (GAC) requires clear, concise guidelines in the form of GAC principles that will be helpful in greening laboratory practices. The existing principles of green chemistry and green engineering need revision for their use in GAC because they do not fully meet the needs of analytical chemistry. In this article we propose a set of 12 principles consisting of known concepts (i.e. reduction in the use of reagents and energy, and elimination of waste, risk and hazard) together with some new ideas (i.e. the use of natural reagents), which will be important for the future of GAC.
