Book Description
In recent years, the fabrication of nanomaterials and exploration of their properties have attracted the attention of various scientific disciplines such as biology, physics, chemistry, and engineering. Although nanoparticulate systems are of significant interest in various scientific and technological areas, there is little known about the safety of these nanoscale objects. It has now been established that the surfaces of nanoparticles are immediately covered by biomolecules (e.g. proteins, ions, and enzymes) upon their entrance into a biological medium. This interaction with the biological medium modulates the surface of the nanoparticles, conferring a “biological identity” to their surfaces (referred to as a “corona”), which determines the subsequent cellular/tissue responses. The new interface between the nanoparticles and the biological medium/proteins, called “bio-nano interface,” has been very rarely studied in detail to date, though the interest in this topic is rapidly growing. In this book, the importance of the physiochemical characteristics of nanoparticles for the properties of the protein corona is discussed in detail, followed by comprehensive descriptions of the methods for assessing the protein-nanoparticle interactions. The advantages and limitations of available corona evaluation methods (e.g. spectroscopy methods, mass spectrometry, nuclear magnetic resonance, electron microscopy, X-ray crystallography, and differential centrifugal sedimentation) are examined in detail, followed by a discussion of the possibilities for enhancing the current methods and a call for new techniques. Moreover, the advantages and disadvantages of protein-nanoparticle interaction phenomena are explored and discussed, with a focus on the biological impacts.

Book Description
This book takes a systematic approach to nanotoxicology and the developing risk factors associated with nanosized particles during manufacture and use of nanotechnology. Beginning with a detailed introduction to engineered nanostructures, the first part of the book presents concepts and definitions of nanomaterials from quantum dots to graphene to fullerenes, with detailed discussion of functionalization, stability, and medical and biological applications. The second part critically examines methodologies used to assess cytotoxicity and genotoxicity. Coverage includes interactions with blood (erythrocytes), combinatorial and microarray techniques, cellular mechanisms, and ecotoxicology assessments. Part three describes cases studies both in vitro and in vivo for specific nanomaterials including solid lipid nanoparticles and nanostructured lipid carriers and metallic nanoparticles and metallic oxides. New information is also presented on toxicological aspects of poloxamers and polymeric nanoparticles as drug carriers as well as size effects on cytotoxicity and genotoxicity. Didactic aspects are emphasized in all chapters, making the book suitable for a broad audience ranging from advanced undergraduate and graduate students to researchers in academia and industry. In all, Nanotoxicology: Materials, Methodologies, and Assessments will provide comprehensive insight into biological and environmental interactions with nanostructures. Provides an introduction to nanostructures actually in use Describes cyto- and genotoxicity methodologies, and assesses their performance in comparison to common toxicity assays Discusses the relation of cytotoxicity and genotoxicity to ecotoxicity Presents a range of applications, from biogenic silver nanoparticles to poloxamers as drug-delivery systems, reflecting the expanding applications of nanotechnology

Book Description
Since the first publication of this book in 2007, the field of nanoscience and nanomedicine continues to grow substantially. This second edition, Nanotoxicology: Progress toward Nanomedicine, enlists internationally recognized experts to document the continuing development and rationale for the safe design of engineered nanomaterials (ENM). This includes new improved characterization endpoints, screening, and detection methods for in vitro and in vivo toxicity testing. These tools also contribute greatly to nanosafety research applied to nanomedicines. Topics include The impacts of nanotechnology on biomedicine, including functionalization for tissue-specific targeting, the biointeractions of multifunctional nanoparticle-based therapy, and the ability to control specific physicochemical properties of nanoparticles The requirements for proper detection, measurement, and assessment both for workplace exposure and in consumer products—with a focus on potential health and safety implications Predictive modeling, using quantitative nanostructure activity relationships to predict the pharmacokinetics and biodistribution of nanomaterials in the body Specific methodologies, imaging, and techniques to assess nanomaterials from the manufacturing process to nanomedicine applications Tools for assessing nanoparticle toxicity and the limitations of detection methods for assessing toxicity in both in vivo and in vitro systems and at the single cell and tissue levels Toxicity of nanomaterials to specific organ systems, cell–based targeting to tumors, and other biomedical applications The difficulty of conducting risk assessments and the need for addressing knowledge gaps, especially with long-term studies A roadmap for future research The development of nanotechnology-based products must be complemented with appropriate validated methods to assess, monitor, manage, and reduce the potential risks of ENM to human health and the environment. This volume provides a cogent survey of advances in this area by a well-respected and diverse group of international scientists.

Book Description
There are many applications for artificial lipid bilayers. These applications include ion channel studies, protein sensing with nanopores--especially DNA sequencing, and artificial lipid bilayers have the potential be applied for use in nanoparticle toxicity screening. Arrays of bilayers were used to test different nanoparticles for interactions in a variety of different environments including changes in particle concentration, ionic strength, pH, and presence of serum. Nanoparticles which were screened for interactions and potentially toxicity with our bilayer array platform included lanthanum oxide, cerium oxide, copper oxide, cobalt oxide, zinc oxide, indium oxide, erbium oxide, europium oxide, and gadolinium oxide. The data from our bilayer array platform also indicated that the ability of nanoparticles to destruct membranes largely depends on experimental conditions. In general, positive coating such as a low pH condition makes the particles more potent to membranes, and less positive coating such as a higher pH makes the particles more or less likely to interact and ultimately disrupt the bilayers. These results about nanoparticles' ability to disrupt and break bilayers have a strong correlation literature regarding nanoparticle toxicity. This information can be used as a platform and starting point to study and predict how other nanoparticles or drugs may interact with bilayers.
