This book was released on 2018 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the increased manufacturing of engineered nanoparticles (ENPs) and their inclusion in consumer products, their presence in the environment is a growing concern. This dissertation focuses on two classes of nanoparticles: plasmonic nanoparticles consisting of monometallic silver (Ag), monometallic gold (Au) and bimetallic silver-gold (Ag-Au) engineered nanoparticles, and iron oxide nanoparticles (IONPs). The goal of the work in this dissertation is to understand the impact of ENPs on chemical and biological contaminants. The first half of the dissertation focuses on the use of plasmonic nanoparticles toward the detection of toxic organophosphorus pollutants, accompanied by understanding the stability of ENPs in environments with excess pesticide residues. The second half of the dissertation focuses on IONPs, which are produced due to their favorable magnetic, catalytic, biomedical, and electronic properties. The increase in manufacturing and use of IONPs has led to their unintentional release into the environment. It is important to take proactive measures to understand the impact of IONPs and other nanoparticles on the environment and on biological species particularly because of the increased chemical reactivity of nanoparticles relative to their bulk counterparts. The work in this dissertation aims to understand the influence of IONPs on microorganisms, with an emphasis on those required for bioremediation. The IONPshave been found to exert severe genotoxicity by entering the cell and interacting with the nucleus, consequently leading to DNA abnormalities and aberrations. The results shed light on the transformations that IONPs undergo in the environment, the genotoxic effect on biological cells, and the impact on the ecosystem.

Download or read book Plant Microbes Engineered Nano particles PM ENPs Nexus in Agro Ecosystems written by Pardeep Singh and published by Springer Nature. This book was released on 2021-03-22 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a collection of cross-disciplinary research, with contributions addressing all key features of the plant/microbe/ENP nexus in agro-ecosystems. The uptake, transport and transformation of nanoparticles in plants have attracted more and more attention in the past several years. Especially, the impact of Engineered Nanoparticles (ENPs) on bioprocesses; low-, medium- and high-level dose responses in the microbial community of soil; and long-, medium- and short-term exposure responses, particularly microbial nitrogen transformations, are just a few of the aspects involved. Since ENPs are used in many industries, including cosmetics, agriculture, medicine, food technology and waste management, their transport through biogeochemical cycles is an important focus of many studies today. Specifically, ENP–microbe interaction has been analysed with regard to disease treatment for plants; it plays a vital role in disease inhibition by releasing metal ions that act through many pathways – e.g. reactive oxygen species (ROS) generation, DNA transformation and disruption of the cell cycle – to stop cell growth in the pathogen. Due to these properties, ENPs are also used as slow release or delayed release pesticides and fungicides, and as carrier systems for growth-promoting hormones. Despite their multiple uses in various industries, the negative effects of ENPs are still a major concern for the scientific community and consumers alike. For example, their transport to various food chains has been reported to have adverse effects. This raises a degree of doubt concerning a rapidly growing scientific field with major applications in many industries. From a sustainable development perspective and particularly to ensure food security in light of the uncertainty accompanying climate change, it is imperative to address this divergence by focusing on the plant/microbe/ENP nexus.
