This book provides a general introduction to nanogels, and designs of various stimuli-sensitive nanogels that are able to control drug release in response to specific stimuli.Nanogels are three-dimensional nanosized networks that formed by physically or chemically crosslinking polymers. They have highly interesting properties such as biocompatibility, high stability, particle size adjustment, drug loading capability and modification of the surface for active targeting. They can respond to stimuli which results in the controlled release of drug and targeting of the site.

Regarding the vast use of chemical components in different human activities, they are susceptible to corrosion because of contact with aggressive environments. Therefore, the use of inhibitors for the control of corrosion of chemical components in corrosive media is an urgent affair. Numerous investigations were carried out and are still being done to study the corrosion inhibition potential of organic compounds. Remarkable inhibition efficiency was achieved by all these compounds particularly some with N, S, and O atoms in their structure. Unfortunately, most of these compounds are not only expensive but also toxic to living beings. Hence, it is essential to mention the importance of natural inhibitors as eco-friendly, readily available, and renewable sources. The main goal of this book is to point out the influence of these components in terms of physical and, in some cases, chemical, processes on different components in aggressive media. Different methods of measuring corrosion, adsorption behavior, mechanism of inhibitors, and some related information is presented in this book. There is a lack of comprehensive and relevant books on this subject, so we decided to write this book in order to accumulate useful information about the influence of natural inhibitors on metals in corrosive areas and to make it accessible to researchers.

Gene therapy as a potential method for treatment of genetic disorders and other malignancies as well as treatment of many cancers has attracted a great amount of attention in recent years.Current research focuses on stable and smart drug/gene delivery systems, including controlled release. Smart nanostructures have been considered as a promising approach when applied to drug and gene delivery systems, and could solve the problems related to the inefficient transfer of medication to the affected cells.
