Available in PDF, EPUB and Kindle. Book excerpt: Molecular Impacts of Nanoparticles on Plants and Algae covers molecular mechanisms of plants/algae related to cellular uptake and translocation of nanoparticles, and genome, transcriptome, proteome, and metabolome responses against it. The book introduces readers to state-of-the-art developments and trends of nanoparticles and plants/algae including interaction of nanoparticles with biological compounds in vitro. Nanoscience and nanotechnology have rapidly been developed in the last few decades, and they have a wide range of applications in industry, medicine, food, and agriculture. In agriculture, nanoparticles (NPs) have successfully been used for growth regulation, crop protection and improvement. They are also employed to cope with plant nutrient deficiencies. A predicted significant increase in the output of NPs will cause the discharge of a remarkable number of NPs to ecosystems, creating a need to understand how to optimize or mitigate their impact depending on their potential impact. These include serious health concerns for living organisms in aquatic, terrestrial, and atmospheric environments as well as human health through their potential existence in plant-based foods. The impact of NPs on living organisms including plants and algae, and uptake, translocation and molecular response mechanisms should be carefully considered before producing and using nanoparticles in large amounts as NPs, when entered to the body, induce changes in gene expressions related to the photosystem, water transport, cell wall formation, and cell division. Further recent studies have showed that NPs are potential agents or stressors to alter proteome, transcriptome, genome and metabolome responses.

Available in PDF, EPUB and Kindle. Book excerpt: The population of the world continues to increase at an alarming rate. The trouble linked with overpopulation ranges from food and water scarcity to inadequacy of space for organisms. Overpopulation is also linked with several other demographic hazards, for instance, population blooming will not only result in exhaustion of natural repositories, but it will also induce intense pressure on the world economy. Today nanotechnology is often discussed as a key discipline of research but it has positive and negative aspects. Also, due to industrialization and ever-increasing population, nano-pollution has been an emerging topic among scientists for investigation and debate. Nanotechnology measures any substance on a macromolecular scale, molecular scale, and even atomic scale. More importantly, nanotechnology deals with the manipulation and control of any matter at the dimension of a single nanometer. Nanotechnology and nanoparticles (NPs) play important roles in sustainable development and environmental challenges as well. NPs possess both harmful and beneficial effects on the environment and its harboring components, such as microbes, plants, and humans. There are many beneficial impacts exerted by nanoparticles, however, including their role in the management of waste water and soil treatment, cosmetics, food packaging, agriculture, biomedicines, pharmaceuticals, renewable energies, and environmental remedies. Conversely, NPs also show some toxic effects on microbes, plants, as well as human beings. It has been reported that use of nanotechnological products leads to the more accumulation of NPs in soil and aquatic ecosystems, which may be detrimental for living organisms. Further, toxic effects of NPs on microbes, invertebrates, and aquatic organisms including algae, has been measured. Scientists have also reported on the negative impact of NPs on plants by discussing the delivery of NPs in plants. Additionally, scientists have also showed that NPs interact with plant cells, which results in alterations in growth, biological function, gene expression, and development. Thus, there has been much investigated and reported on NPs and plant interactions in the last decade. This book discusses the most recent work on NPs and plant interaction, which should be useful for scientists working in nanotechnology across a wide variety of disciplines.

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.

Download or read book Analytical Models to Understand Interactions at the Nano bio Interface written by Christian A. Reardon-Lochbaum and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials are synthesized for use in a wide variety of consumer and industrial products, which will inadvertently lead to nanomaterial exposure to biological systems; additionally, nanomaterials are being explored for application in both the medical and agricultural fields, which constitutes intentional nanomaterial exposure to biological systems. With the rapid expansion in the quantity and variety of nanomaterials being synthesized, it has become a huge undertaking to characterize the interactions at the nano-bio interface. Here, I present a series of studies that work towards developing and utilizing model systems to characterize interactions between nanomaterials and cellular membranes or biological fluids. This work targets two model membrane systems-the supported lipid bilayer and unilamellar vesicles-and one biological fluid model system-plant xylem fluid. Membranes make up one of the cells most robust defense systems from invasive material. They provide both a physical and chemical barrier between the interior and exterior of the cell. Cellular membranes are complex, containing multitudes of different lipid varieties that assemble into surface features and incorporate membrane proteins that actively perform tasks while contained within the bilayer. Due to this complexity, interactions between native cell membranes and nanoparticles are difficult to characterize when performing whole cell exposure studies. Lipid bilayer model systems simplify the cell membrane down to a handful of molecular components so that fundamental mechanisms of interaction between nanoparticles and lipids can be studied. The work presented here has focused on the simplest variety of model lipid bilayer, the single component lipid bilayer, to allow for rigorous characterization of molecular interactions with nanomaterials. We used the first model system highlighted here, supported lipid bilayers, to understand the interactions between ligand coated gold nanoparticles and cellular membranes. We exposed supported lipid bilayers to 2 nm gold nanoparticles functionalized with ligands of systematically increasing lipophilicity. We found that increasing lipophilicity of ligands increased the maximum mass density of nanoparticle adsorption and the rate at which nanoparticles converted to the quasi-irreversibly adsorbed state. The quasi-irreversibly bound state was linked to ligand insertion, which we define by the ability of a ligand to form hydrophobic contact with lipid tail groups. An issue with previous applications of the supported lipid bilayer system is that it under predicts the interaction of anionic nanoparticles with the membrane when compared to both computational and cellular exposure models. We found that interactions between anionic nanoparticles and supported lipid bilayers are impacted by the composition of the substrate upon which the bilayer is built. Specifically, we find that SiO2-a widely used substrate-hindered the adsorption of anionic gold nanoparticles to the bilayer as compared to a Au substrate. This change is attributed to both the increased attractive van der Waals forces and decreased repulsive Coulombic forces of nanoparticles interacting with bilayers formed on Au vs SiO2 substrates, respectively. A second model membrane system, unilamellar vesicles, has been used to monitor nanomaterial induced disruption or remodeling of lipid bilayers; however, a difficulty when using this model system is the inability to rigorously track the nanomaterial with respect to a disruption or remodeling event, due to the small size dimensions of the nanoparticle. We work to develop a method of tracking both fluorescent vesicles and nanomaterials simultaneously with convex lens induced confinement. The final set of studies presented here utilizes a third model biological system: plant xylem fluid. Nanomaterial based approaches to suppressing plant disease and increasing crop yields are being explored; however, little is known about molecular level interactions between the nanomaterials proposed in this research and the plants. We conducted a set of measurements to understand how copper oxide nanoparticles, a nanomaterial that has shown promise as a micronutrient delivery to plants, interact with the biomolecules found in xylem fluid. We found that proteins from the xylem fluid associate with the nanoparticles, a phenomenon known as biomolecular corona formation. Additionally, we found that protein adsorption is selective to a subset of proteins found within the xylem fluid and the corona evolves over time.0́3
