Book Description
The theoretical background of this work is concerning with the drug loaded polyelectrolyte multilayers (PEM) modified by the host-guest interaction of biocompatible hyperbranched core-shell glycopolymers. The glycopolymer in this work is the hyperbranched polyethyleneimine that was modified with maltose moieties using reductive amination. Thus, the use of glycohyperbranched polymers for drug delivery would allow the avoid naturally occurring drug resistance due to decreased transporter activity. Concerning preparative method, PEM was fabricated using layer-by-layer (LbL) processes involve the sequential deposition of two polyions that physically bond together. Control was taken on the stoichiometric ratio related to cationic and anionic repeating units, which was chosen close to zero for the final applied PEM. Concerning analytical methods, a couple of physical-chemical methods were applied to characterize colloid stability, adhesiveness, drug loading and release of fabricated PEM. In conclusion, a highly sable and sustainable PEM coats on a surface of an activated solid substrate has been fabricated with an efficient ability to recycle the charged molecule for more than 24 times.

Book Description
This book addresses the need for a comprehensive book on the design, synthesis, and characterization of synthetic carbohydrate-based polymeric materials along with their biological applications. The first two chapters cover the synthesis and self-assembly of glycopolymers and different techniques for creating these synthetic polymers. Subsequent chapters account for the preparation of block copolymers, branched glycopolymers, glycosurfaces, glycodendrimers, cationic glycopolymers, bioconjugates, glyconanoparticles and hydrogels. While these chapters comprehensively review the synthetic and characterization methods of those carbohydrate-based materials, their biological applications are discussed in detail.

Book Description
Smart Nanocontainers explores the fundamental concepts and emerging applications of nanocontainers in biomedicine, pharmaceuticals and smart materials. In pharmaceuticals, nanocontainers have advantages over their micro-counterparts, including more efficient drug detoxification, higher intracellular uptake, better stability, less side effects and higher biocompatibility with tissue and cells. In materials science, such as coating technology, they help by making coatings smarter, stronger and more durable. This important reference will help anyone who wants to learn more on how nanocontainers are used to provide the controlled release of active agents, including their applications in smart coatings, corrosion, drug delivery, diagnosis, agri-food and gas storage. - Discusses how the molecular design of nanocarriers can be optimized to increase performance - Explores how nanocarriers are being used to produce a new generation of active coatings - Explains how nanocarriers are being used to deliver more effective nanoscale drug delivery

Book Description
At the interface of biology, chemistry, and materials science, this book provides an overview of this vibrant research field, treating the seemingly distinct disciplines in a unified way by adopting the common viewpoint of surface science. The editors, themselves prolific researchers, have assembled here a team of top-notch international scientists who read like a "who's who" of biomaterials science and engineering. They cover topics ranging from micro- and nanostructuring for imparting functionality in a top-down manner to the bottom-up fabrication of gradient surfaces by self-assembly, from interfaces between biomaterials and living matter to smart, stimuli-responsive surfaces, and from cell and surface mechanics to the elucidation of cell-chip interactions in biomedical devices. As a result, the book explains the complex interplay of cell behavior and the physics and materials science of artificial devices. Of equal interest to young, ambitious scientists as well as to experienced researchers.

Book Description
The term biomimetic is comparatively new on the chemical scene, but the concept has been utilized by chemists for many years. Furthermore, the basic idea of making a synthetic material that can imitate the func tions of natural materials probably could be traced back into antiquity. From the dawn of creation, people have probably attempted to duplicate or modify the activities of the natural world. (One can even find allusions to these attempts in the Bible; e. g. , Genesis 30. ) The term "mimetic" means to imitate or mimic. The word "mimic" means to copy closely, or to imitate accurately. Biomimetic, which has not yet entered most dictionaries, means to imitate or mimic some specific bio logical function. Usually, the objective of biomimetics is to form some useful material without the need of utilizing living systems. In a simi lar manner, the term biomimetic polymers means creating synthetic poly mers which imitate the activity of natural bioactive polymers. This is a major advance in polymer chemistry because the natural bioactive polymers are the basis of life itself. Thus, biomimetic polymers imitate the life process in many ways. This present volume delineates some of the recent progress being made in this vast field of biomimetic polymers. Chemists have been making biomimetic polymers for more than fifty years, although this term wasn't used in the early investigations.

Book Description
Hydrogels, as three-dimensional polymer networks, are able to retain a large amount of water in their swollen state. The biomedical application of hydrogels was initially hampered by the toxicity of cross-linking agents and the limitations of hydrogel formation under physiological conditions. However, emerging knowledge in polymer chemistry and an increased understanding of biological processes have resulted in the design of versatile materials and minimally invasive therapies.The novel but challenging properties of hydrogels are attracting the attention of researchers in the biological, medical, and pharmaceutical fields. In the last few years, new methods have been developed for the preparation of hydrophilic polymers and hydrogels, which may be used in future biomedical and drug delivery applications. Such efforts include the synthesis of self-organized nanostructures based on triblock copolymers with applications in controlled drug delivery. These hydrogels could be used as carriers for drug delivery when combined with the techniques of drug imprinting and subsequent release. Engineered protein hydrogels have many potential advantages. They are excellent biomaterials and biodegradables. Furthermore, they could encapsulate drugs and be used in injectable forms to replace surgery, to repair damaged cartilage, in regenerative medicine, or in tissue engineering. Also, they have potential applications in gene therapy, although this field is relatively new.
