Nanoparticles have numerous biomedical applications including drug delivery, bone implants and imaging. A protein corona is formed when proteins existing in a biological system cover the nanoparticle surface. The formation of a nanoparticle–protein corona, changes the behaviour of the nanoparticle, resulting in new biological characteristics and influencing the circulation lifetime, accumulation, toxicity, cellular uptake and agglomeration. This book provides a detailed understanding of nanoparticle–protein corona formation, its biological significance and the factors that govern the formation of coronas. It also explains the impact of nanoparticle–protein interactions on biological assays, ecotoxicity studies and proteomics research. It will be of interest to researchers studying the application of nanoparticles as well as toxicologists and pharmaceutical chemists.

Concerns about the adverse effects of chemicals present in the environment have created a need for better systems to assess their potential consequences on human health. One potential solution is the versatile and state-of-the-art Comet assay. Simple, sensitive, rapid and visual, this modern toxicological method allows quantitative and qualitative assessment of DNA damage in single cells. This assay is used in diverse fields ranging from clinical applications, human monitoring and environmental toxicology through to genetic toxicity testing. This updated and revised edition of The Comet Assay in Toxicology provides the latest information on this important tool. It addresses, in-depth, the different protocols, statistical analyses and applications used worldwide. It also includes the guidelines recommended by the Working Group on Comet Assay. The book begins with a review of the genesis of the assay for those new to the technique and goes on to explain procedures followed to assess different types of DNA damage, various applications of the assay, and guidelines for the conduct of the assay in in vitro and in vivo systems. New chapters written for this edition will provide information on the most contemporary approaches and applications, including in silico approaches, on meta-analysis of data and on the application of the Comet Assay in nanotoxicology. This book will serve as both a reference and a guide to students as well as investigators in the biomedical, biochemical and pharmaceutical sciences fields.

This current edition explores new tests for genotoxicity testing, along with other well-known techniques. This will further help in our understanding of the genotoxic effects of chemicals. The book has different sections dealing with various assays for gene mutation, chromosomal abnormalities, primary DNA damage, etc. It also delves into plant models, animals and their alternates, as well as in silico approaches for genetic toxicology. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Genotoxicity Assessment: Methods and Protocols, Second Edition serves as a highly useful and ready resource for research students and scientists working in regulatory toxicology as well as biomedical, biochemical, and pharmaceutical sciences.
