Toxicity Of Nanoparticles In Plants

Toxicity of Nanoparticles in Plants: An Evaluation of Cyto/Morpho-physiological, Biochemical and Molecular Responses, Volume Five in the Nanomaterial-Plant Interactions series, reviews the latest research on toxicological effects of using nanotechnology in plants. Key themes include analyzing plant exposure to nanomaterials, mechanisms of toxicity of nanoparticles to plants, and effects, uptake and translocation of various different nanoparticles. This will be an essential read for any scientist or researcher looking to assess and understand the potential toxicological risks associated with plant nanotechnology. To date, nanotechnology is considered one of the most promising areas of research due to the widespread applications of nanomaterials in plant science and agriculture. However, extensive use of nano-based products raises concerns regarding their toxicity in crop plants, their environmental impact and potential consequences to humans via the food chain. Discusses environmental concerns raised by the extensive use of nanotechnology Highlights the impact of plants treated with nanoparticles on nutritional status Reviews major challenges for assessing the toxicity of nanomaterials in plants

This book provides relevant findings on nanoparticles’ toxicity, their uptake, translocation and mechanisms of interaction with plants at cellular and sub-cellular level. The small size and large specific surface area of nanoparticles endow them with high chemical reactivity and intrinsic toxicity. Such unique physicochemical properties draw global attention of scientists to study potential risks and adverse effects of nanoparticles in the environment. Their toxicity has pronounced effects and consequences for plants and ultimately the whole ecosystem. Plants growing in nanomaterials-polluted sites may exhibit altered metabolism, growth reduction, and lower biomass production. Nanoparticles can adhere to plant roots and exert physicochemical toxicity and subsequently cell death in plants. On the other hand, plants have developed various defense mechanisms against this induced toxicity. This books discusses recent findings as well as several unresolved issues and challenges regarding the interaction and biological effects of nanoparticles. Only detailed studies of these processes and mechanisms will allow researchers to understand the complex plant-nanomaterial interactions.

"Toxic Effects of Nanomaterials provides an authoritative work of international experts in the field of nanotoxicology spanning 8 chapters. A key feature of the e-book is a broad coverage of phytotoxicity of nanoparticles, which is largely neglected in man"

Plants encounter a wide range of environmental challenges during their life cycle, among which nanoparticle toxicity is a common form of abiotic stress. Nanoparticles can adversely affect various stages of the plant life cycle, such as seed germination, root and shoot growth, chloroplasts ultrastructure and photosynthesis, nutrients assimilation, carbohydrates metabolism, and plant hormonal status, which collectively result in reduced plant yields. Sources, Mechanisms and Toxicity of Nanomaterials in Plants discusses the plant physiology and chemistry involved when plants encounter nanoparticles. Key topics include effects of nanoparticles on photosynthetic responses, regulation of nanoparticle toxicity by nitric oxide, and regulation of nanoparticle toxicity by exogenous application of primary and secondary metabolites. This is the first volume in the new Nanomaterials-Plant Interactions series and is an essential read to all researchers and scientists interested in plant physiology and chemistry, agronomy, nanotechnology and environmental science. Analyses how nanoparticle toxicity impacts the plant life cycle Includes the latest information on the range of coping mechanisms plants use to combat nanotoxicity Reviews protectants, such as endogenous signaling molecules, and their role in protecting the plant from nanotoxicity

This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.
