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.

Bionanomaterials are identified as a perfect replacement, in the quest for the search of an alternative to toxic conventional nanomaterials for biomedical applications. Bionanomaterials are the nanomaterials, that are fabricated via biomolecules or encapsulate or immobilize a conventional nanomaterial with a biomolecule. The biomolecules extracted from the microbes, plants, agricultural wastes, insects, marine organisms and certain animals are used for the formation of bionanomaterials. These bionanomaterials exhibited low or negligible toxicity towards humans, other organisms and the environment with enhanced biocompatibility, bioavailability and bioreactivity. Thus, the aim of this book is to provide an overview of various bionanomaterials, their synthesis, characterization and their application-oriented properties. The book is divided into two parts – Part 1 discusses about the bionanomaterials of exclusive natural origin, self-assembled bionanomaterials and their environmental application and Part 2 focuses on applications of distinct bionanomaterials in biomedical sciences. The ‘Chapter 1 – Bionanomaterials: Definitions, sources, types, properties, market, toxicity and regulations’ aims to provide an extensive overview of bionanomaterials, their definitions, sources, types and their properties. In addition, the toxicity of bionanomaterials and their regulations implied in recent times were also discussed. ‘Chapter 2 – Nature inspired bionanomaterials’ highlights different types of nature-inspired biosynthesized nanomaterials and their green synthesis methods, as well as some of their emerging applications, especially in the fields of nanomedicine, cosmetics, drug delivery, molecular imaging, and catalytic precursors.

Separations of Water Pollutants with Nanotechnology, the latest volume in the Separation Science and Technology series, offers new solutions for remediating water pollution utilizing nanomaterials with separation methods. Current water purification methods are unsuitable, inconvenient or expensive, so there is a need for new and better processes and techniques. Nanomaterials can purify water by removing pollutants such as heavy metals, pathogens, organic compounds, inorganic compounds, pharmaceuticals, and chemicals of emerging concern. These can effectively replace membrane-based methods if the right expertise is developed—this book helps separation scientists do just that. Existing water treatment problems can be solved by applying a nanotechnology-based processes: antimicrobial nanotechnology, zero-valent iron nanoparticles, nanoadsorbents, nano-enhanced membranes, nanometal oxides, and nano photocatalysts. The current literature places emphasis on materials chemistry rather than the separation methods used for water purification. This new volume presents a collection of chapters that deal with remediation based on separation chemistry.
