This Brief provides an up-to-date overview of smart surfactants and describes a broad spectrum of triggers that induce the formation of wormlike micelles or reversibly tune the morphology of surfactant aggregates from wormlike micelles to another state, or vice versa. Combining the fields of chemistry, physics, polymer science, and nanotechnology, its primary focus is on the design, formulation, and processing of intelligent viscoelastic surfactant solutions, covering the scientific principles governing responsiveness to one or more particular triggers, down to the end-use-driven functions. The first chapter explains why and how surfactants self-assemble into viscoelastic wormlike micellar solutions reminiscent of polymer solutions, while the following chapters show how the response to a given trigger translates into macroscopic rheological changes, including temperature, light, pH, CO2, redox, hydrocarbon, etc. The last chapter demonstrates the applications of these viscoelastic assemblies in oil and gas production, drag reduction, biomaterials, cleaning processes, electrorheological and photorheological fluids. Comments and perspectives are provided at the end to conclude this Brief. This Brief is aimed at chemists, physicists, chemical engineers and nano-scientists who are involved in self-assemblies and applications of surfactants, as well as graduates in physical chemistry.

Wormlike micelles are elongated flexible self-assembled structures created from the aggregation of amphiphiles and their resulting dynamic networks have gained attention for a number of uses, particularly in the oil industry. Written by experts, Wormlike Micelles describes the latest developments in the field providing an authoritative guide on the subject. The book starts with an introductory chapter giving an overview of the area and then looks at the three key topics of new wormlike micelle systems, characterization and applications. New systems covered in the first part include reverse wormlike micelles and stimuli-responsive wormlike micelles. The second part explores cutting-edge techniques that have led to advances in the understanding of their structure and dynamics, including direct imaging techniques and the combination of rheology with small-angle neutron scattering techniques. Finally, the book reviews their use in oil and gas well treatments as well as surfactant drag reducing solutions. Aimed at postgraduate students and researchers, this text is essential reading for anyone interested in soft matter systems.

Generating much interest in both academic and scientific circles, Gemini Surfactants gathers the most up-to-date research in gemini surfactantproduction and demonstrates how their propertiesand performance can revolutionize the current industrial application of these surfactants. It surveys the state of special gemini surfactants, including nonionic, zwitterionic, fluorinated, and amino-acid-based surfactants. Gemini Surfactants considers the synthesis, phase behavior, and rheology of gemini and related surfactants and clarifies the adsorption and surface tension behavior of gemini surfactants at air–water, oil–water, and solid–water interfaces. The book also details the physicochemical properties and microstructure of aqueous micellar solutions of gemini surfactants and describes mixed micellization between gemini surfactants and conventional surfactants.

The concept of smart drug delivery vehicles involves designing and preparing a nanostructure (or microstructure) that can be loaded with a cargo. This can be a therapeutic drug, a contrast agent for imaging, or a nucleic acid for gene therapy. The nanocarrier serves to protect the cargo from degradation by enzymes in the body, to enhance the solubility of insoluble drugs, to extend the circulation half-life, and to enhance its penetration and accumulation at the target site. Importantly, smart nanocarriers can be designed to be responsive to a specific stimulus, so that the cargo is only released or activated when desired. In this volume we cover smart nanocarriers that respond to internal stimuli that are intrinsic to the target site. These stimuli are specific to the cell type, tissue or organ type, or to the disease state (cancer, infection, inflammation etc). pH-responsive nanostructures can be used for cargo release in acidic endosomal compartments, in the lower pH of tumors, and for specific oral delivery either to the stomach or intestine. Nanocarriers can be designed to be substrates of a wide-range of enzymes that are over-expressed at disease sites. Oxidation and reduction reactions can be taken advantage of in smart nanocarriers by judicious molecular design. Likewise, nanocarriers can be designed to respond to a range of specific biomolecules that may occur at the target site. In this volume we also cover dual and multi-responsive systems that combine stimuli that could be either internal or external.
