Although in nature the vast majority of polymers are condensation polymers, much publicity has been focused on functionalized vinyl polymers. Functional Condensation Polymers fulfills the need to explore these polymers which form an increasingly important and diverse foundation in the search for new materials in the twentyfirst century. Some of the advantages condensation polymers hold over vinyl polymers include offering different kinds of binding sites, their ability to be made biodegradable, and their different reactivities with various reagents under diverse reaction conditions. They also offer better tailoring of end-products, different tendencies (such as fiber formation), and different physical and chemical properties. Some of the main areas emphasized include dendrimers, control release of drugs, nanostructure materials, controlled biomedical recognition, and controllable electrolyte and electrical properties.
The interface between a living cell and the surrounding world plays a critical role in numerous complex biological processes. Sperm/egg fusion, virus/cell fusion, exocytosis, endocytosis, and ion permeation are a few examples of processes involving membranes. In recent years, powerful tools such as X-ray crystal lography, electron microscopy, nuclear magnetic resonance, and infra-red and Raman spectroscopy have been developed to characterize the structure and dy namics of biomembranes. Despite this progress, many of the factors responsible for the function of biomembranes are still not well understood. The membrane is a very complicated supramolecular liquid-crystalline structure that is lar...

Nanomaterials, with their unique size-dependent physical and chemical properties, have shown promising advantages as drug and gene delivery vehicles, ultra-sensitive intracellular detectors and novel therapeutic drugs. Nanopharmaceutics is one of the disciplines that will benefit the most from this technology.Nanotechnology will have a revolutionary impact on cancer diagnosis and therapy due to the exceptional characteristics of nanopharmaceutics.This book provides an overview of some tools, methods, and materials of nanotechnology that offer potential applications in pharmaceutics, followed by a series of examples showing applications that are already in development. It may very well inspire researchers to develop a new generation of pharmaceutics with inventive non-traditional approach and employ nanoscale science for the benefit of the patient.
Based on the International Workshop on Controlled Life-Cycle of Polymeric Materials held in Stockholm, this work examines degradable polymers and the recycling of plastic materials. It highlights recent results on recycling and waste management, including topics such as renewable resources, degradation, processing and products, and environmental issues.
Nearly 4000 years ago, the Egyptians used linen, a natural polymeric material, for suturing wounds. About 600 B.C., the Indians used other forms of natural polymers such as cotton, horse hair, and leather in repairing wounds. Wound closure procedures using silk sutures, based mostly on polypeptides, are likely to have been practiced during the second century. Surgical application of natural polymers continued to represent the major use of polymers until the twentieth century. Not too long after the development of several major synthetic polymers, their use in biomedical applications has attracted the attention of many re searchers and clinicians. Over the past few years, interest in the biom...
The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modific...
Handbook of Biodegradable Polymers, the seventh volume in the Drug Delivery and Targeting book series, provides a source manual for synthetic procedures, properties and applications of bioerodible polymers. The authors describe widely available materials such as polyactides, collagen and gelatin, as well as polymers of emerging importance, such as the genetically-engineered and elastin-based polymers which are either proprietary or in early stages of development. Section I addresses synthetic absorbable polymers, and Section 2 profiles natural, semi-synthetic and biosynthetic polymers. Section 3 discusses the surface characterization of degradable polymers, the modeling of biodegradation and non-medical polymers. This book is ideal for researchers from academia and industry as well as chemists, pharmacists and physicians who deal with biopolymers, drug delivery and targeting, bioengineering and implantable devices.
The biological and biomedical applications of polymeric materials have increased greatly in the past few years. This book will detail some, but not all, of these recent developments. There would not be enough space in this book to cover, even lightly, all of the major advances that have occurred. Some earlier books and summaries are available by two of this book's Editors (Gebelein & Carraher) and these should be consul ted for additional information. The books are: "Bioactive Polymeric Systems" (Plenum, 1985); "Polymeric Materials In Medication" (Plenum, 1985); "Biological Acti vi ties of Polymers" (American Chemical Society, 1982). Of these three, "Bioacti ve Polymeric Systems" should be t...
