BIOLOGICALLY ACTIVE COPOLYMERS by Dr. P. Pazhanisamy & Dr. S. Bharathi Pdf

1.1 Polymer The history of polymers goes back further than that of any other group of substances known to mankind. From the origin of mankind in the Garden of Eden, dependence was upon naturally-occurring polymers, for food, clothing, shelter and communication. On the contrary, the history of synthetic polymers is relatively short. It was only through the pioneering work of Staudinger and the quantitative studies of Carothers, the macromolecular concept was accepted. Long before this time, synthetic polymers were being produced and natural polymers were being altered chemically. Styrene was first polymerized in 1839 and in the same year the process of vulcanization of rubber was made successful. 1.2 Description and classification The word polymer was first used to describe compounds with the same composition but of different molecular weights. Berzelius defined polymer as ‘many of a unit’. Carothers defined polymerization as a reaction that is functionally capable of proceeding indefinitely. According to IUPAC, a monomer is defined as ‘a compound, consisting of molecules each of which can provide one or more constitutional units of a polymer or oligomer’ and a monomeric unit or “mer” is the ‘largest constitutional unit contributed by a single monomer molecule in a polymerization processes.

Living and Controlled Polymerization by Joseph Jagur-Grodzinski Pdf

The living/controlled polymerisation techniques opened new vistas in polymer chemistry. The leading authorities in this field and its pioneers contributed chapters to this collective volume. The controlled polymerisation techniques have enabled preparation of polymers, copolymers, and block copolymers with predetermined molecular weights and narrow polydispersity, in which functional groups or biologically active molecules could be placed at well defined locations. They have also enabled preparation of advanced polymeric structures with precisely determined architectures and improved properties. Moreover, they have provided opportunities for preparation of novel polymeric materials from monomers, which before have not been suitable or accessible for such purposes. Properties of some of these polymeric materials may be significantly different from those of the existing ones. They provide opportunities for new applications. Several patents have already been approved for such speciality applications as, drug delivery, biocompatible surfaces, thermoplastic elastomers, moisture curable sealants, and so on. Many more products, based on polymers fabricated by the living/ controlled polymerisation techniques, will certainly emerge in such specialised areas as, nanotechnology, medical devices, "smart polymers", sensors , smart separation technologies, optical fibres and other optical applications, various biomaterials, etc.

Bioactive Polymeric Systems by Charles G. Gebelein,Charles E. Carraher Pdf

The vast array of libraries in the world bear mute witness to the truth of the 3000-year-old observation of King Solomon who stated " ... of making many books there is no end, and much study is a weariness of the flesh." Yet books are an essential written record of our lives and the progress of science and humanity. Here is another book to add to this huge collection, but, hopefully, not just another collection of pages, but rather a book with a specific purpose to aid in alleviating the "weariness of the flesh" that could arise from much studying of other journals and books in order to obtain the basic information contained herein. This book is about polymeric materials and biological activity, as the title notes. Polymeric materials, in the broad view taken here, would include not only synthetic polymers (e.g., polyethylene, polyvinyl chloride, polyesters, polyamides, etc.), but also the natural macromolecules (e.g., proteins, nucleic acids, polysaccharides) which compose natural tissues in humans, animals and plants. In the broad sense used here, biological activity is any type of such action whether it be in medication, pest control, plant-growth regu lation, and so on. In short, this book attempts to consider, briefly, the use of any type of polymeric material system with essentially any kind of biological activity.

Biomimetic, Bioresponsive, and Bioactive Materials by Matteo Santin,Gary J. Phillips Pdf

The accessible introduction to biomaterials and their applications in tissue replacement, medical devices, and more Molecular and cell biology is being increasingly integrated into the search for high-performance biomaterials and biomedical devices, transforming a formerly engineering- and materials science–based field into a truly interdisciplinary area of investigation. Biomimetic, Bioresponsive, and Bioactive Materials presents a comprehensive introduction to biomaterials, discussing how they are selected, designed, and modified for integration with living tissue and how they can be utilized in the development of medical devices, orthopedics, and other related areas. Examining the physico chemical properties of widely used biomaterials and their uses in different clinical fields, the book explores applications including soft and hard tissue replacement; biointeractive metals, polymers, and ceramics; and in vitro, in vivo, and ex vivo biocompatibility tests and clinical trials. The book critically assesses the clinical level of research in the field, not only presenting proven research, but also positing new avenues of exploration. Biomimetic, Bioresponsive, and Bioactive Materials contains everything needed to get a firm grasp on materials science, fast. Written in an accessible style and including practice questions that test comprehension of the material covered in each chapter, the book is an invaluable tool for students as well as professionals new to the field.

Block Co-polymeric Nanocarriers: Design, Concept, and Therapeutic Applications by Neeraj Mishra,Vikas Pandey Pdf

This book focuses on current advancements in the field of block copolymers and covers design, concept, and various therapeutic applications in the drug delivery. It also reviews the use of block copolymers in drug delivery applications from the development of sustained release products to smart polymeric delivery systems such as stimuli-responsive polymeric systems, for example, thermosensitive, redox-sensitive, photo-sensitive, and enzyme-sensitive. The book further discusses the nano assemblies from amphiphilic block copolymers as nanomedicine platforms for diagnosis and therapy due to their relatively small size, high drug loading capacity, controlled drug release, in vivo stability, and prolonged blood circulation. The chapters also review the various patents and ongoing clinical trials on the applications, covering several important new concepts and findings in the field of block copolymers. The book is aimed at researchers, academicians, and industrial scientists involved in the development of drug-delivery systems based on polymers.
