Book Description
This text details the plant-assisted remediation method, “phytoremediation”, which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, metalloids, fuel and oil hydrocarbons, nano particles, pesticides, solvents, organic compounds and various other contaminants. Many chapters highlight and compare the efficiency and economic advantages of phytoremediation and nano-phytoremediation to currently practiced soil and water treatment practices. Volume 6 of Phytoremediation: Management of Environmental Contaminants continues the series. Taken together, the six volumes provide a broad–based global synopsis of the current applications of phytoremediation using plants and the microbial communities associated with their roots to decontaminate terrestrial and aquatic ecosystems.

Book Description
This book provides detailed reviews of a range of nanostructures used in the construction of biosensors as well as the applications of these biosensor nanotechnologies in the biological, chemical, and environmental monitoring fields Biological sensing is a fundamental tool for understanding living systems, but also finds practical application in medicine, drug discovery, process control, food safety, environmental monitoring, defense, and personal security. Moreover, a deeper understanding of the bio/electronic interface leads us towards new horizons in areas such as bionics, power generation, and computing. Advances in telecommunications, expert systems, and distributed diagnostics prompt us to question the current ways we deliver healthcare, while robust industrial sensors enable new paradigms in R&D and production. Despite these advances, there is a glaring absence of suitably robust and convenient sensors for body chemistries. This book examines some of the emerging technologies that are fueling scientific discovery and underpinning new products to enhance the length and quality of our lives. The 14 chapters written by leading experts cover such topics as: ZnO and graphene microelectrode applications in biosensing Assembly of polymers/metal nanoparticles Gold nanoparticle-based electrochemical biosensors Impedimetric DNA sensing employing nanomaterials Graphene and carbon nanotube-based biosensors Computational nanochemistry study of the BFPF green fluorescent protein chromophore Biosynthesis of metal nanoparticles Bioconjugated-nanoporous gold films in electrochemical biosensors The combination of molecular imprinting and nanotechnology Principles and properties of multiferroics and ceramics

Book Description
Bioremediation refers to the clean‐up of pollution in soil, groundwater, surface water, and air using typically microbiological processes. It uses naturally occurring bacteria and fungi or plants to degrade, transform or detoxify hazardous substances to human health or the environment. For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only where environmental conditions permit microbial growth and action, its application often involves the management of ecological factors to allow microbial growth and degradation to continue at a faster rate. Like other technologies, bioremediation has its limitations. Some contaminants, such as chlorinated organic or high aromatic hydrocarbons, are resistant to microbial attack. They are degraded either gradually or not at all, hence, it is not easy to envisage the rates of clean-up for bioremediation implementation. Bioremediation represents a field of great expansion due to the important development of new technologies. Among them, several decades on metagenomics expansion has led to the detection of autochthonous microbiota that plays a key role during transformation. Transcriptomic guides us to know the expression of key genes and proteomics allow the characterization of proteins that conduct specific reactions. In this book we show specific technologies applied in bioremediation of main interest for research in the field, with special attention on fungi, which have been poorly studied microorganisms. Finally, new approaches in the field, such as CRISPR-CAS9, are also discussed. Lastly, it introduces management strategies, such as bioremediation application for managing affected environment and bioremediation approaches. Examples of successful bioremediation applications are illustrated in radionuclide entrapment and retardation, soil stabilization and remediation of polycyclic aromatic hydrocarbons, phenols, plastics or fluorinated compounds. Other emerging bioremediation methods include electro bioremediation, microbe-availed phytoremediation, genetic recombinant technologies in enhancing plants in accumulation of inorganic metals, and metalloids as well as degradation of organic pollutants, protein-metabolic engineering to increase bioremediation efficiency, including nanotechnology applications are also discussed.

Book Description
In this book the recent progress accumulated in studies of the interaction of engineered nanoparticles with cells and cellular constituents is presented. The focus is on manufacturing and characterization of nanosized materials, their interactions with biological molecules such as proteins, the mechanisms of transport across biological membranes as well as their effects on biological functions. Fundamental molecular and cellular aspects are in the foreground of the book. A further particularity is the interdisciplinary approach, including fields such as preparatory and analytical chemistry, biophysics and the physics of colloids, advanced microscopy and spectroscopy for in-situ detection of nanoparticles, cellular toxicology and nanomedicine. Nanoscale particles are known to exhibit novel and unprecedented properties that make them different from their corresponding bulk materials. As our ability to control these properties is further advanced, a huge potential to create materials with novel properties and applications emerges. Although the technological and economic benefits of nanomaterials are indisputable, concerns have also been raised that nanoscale structuring of materials might also induce negative health effects. Unfortunately, such negative health effects cannot be deduced from the known toxicity of the corresponding macroscopic material. As a result, there is a major gap in the knowledge necessary for assessing their risk to human health.
