The important role of ?nely dispersed matter and surfaces in medicine is not always fully understood and appreciated. Speci?cally, ?ne particles (solid or liquid) in the size range of several nanometers to several micrometers have a tremendous effect on our lives, because they can be bene?cial or detrimental to our well-being. Such particles are present in living bodies as red blood cells or cholesterol crystals in the gall bladder. They are ubiquitous in the environment, where they can cause many diseases, such as asbestosis, silicosis, and black lung disease, but they are also used in diagnostic tests, drug delivery, and numerous other applications. More recently, evidence has become available that drug formulations with active components in a ?nely dispersed state may signi?cantly affect their functionality. Furthermore, with miniaturization of medical instrumentation, the size of the components is necess- ily reduced to colloid or even smaller range. This volume is a collection of several chapters dealing with diverse topics of colloids and surfaces relevant to medical applications. Thus, Siiman describes the use of optical properties of uniform colloidal particles as probes in ?ow cytometry. Giesche focuses on the preparations and properties of exceedingly uniform silica spheres for different uses, such as in chromatography. In modi?ed forms, silica p- ticles with incorporated dyes are employed in diagnostics and those combined with tiny magnetic entities in drug delivery.

Colloids are submicron particles that are ubiquitous in both natural and industrial products. Colloids and colloidal systems play a significant role in human health as well as commercial and industrial situations. Colloids have important applications in medicine, sewage disposal, water purification, mining, photography, electroplating, agriculture, and more.This book gathers recent research from experts in the field of colloids and discusses several aspects of colloid morphology, synthesis, and applications. The book is divided into three sections that cover different techniques for the synthesis of colloids, the structure, dynamic and stability of colloids, and applications of colloidal particles, respectively.

Colloidal science and technology is one of the fastest growing research and technology areas. This book explores the cutting edge research in colloidal science and technology that will be useful in almost every aspect of modern society. This book has a depth of information related to historical prospective, synthesis, characterisation, theoretical modelling and application of unique class of colloidal materials starting from colloidal gold to coated silica colloid and platinum, titania colloids. This book is unique in its design, content, providing depth of science about different colloidal materials and their applications in chemistry, physics, biological, medical sciences and environment. Graduate students, academic and industrial researchers and medical professionals will discover recently developed colloidal materials and their applications in many areas of human endeavours through this book.

Colloid and Interface Science in Pharmaceutical Research and Development describes the role of colloid and surface chemistry in the pharmaceutical sciences. It gives a detailed account of colloid theory, and explains physicochemical properties of the colloidal-pharmaceutical systems, and the methods for their measurement. The book starts with fundamentals in Part I, covering fundamental aspects of colloid and interface sciences as applied to pharmaceutical sciences and thus should be suitable for teaching. Parts II and III treat applications and measurements, and they explains the application of these properties and their influence and use for the development of new drugs. Provides a clear description of the fundamentals of colloid and interface science relevant to drug research and development Explains the physicochemical/colloidal basis of pharmaceutical science Lists modern experimental characterization techniques, provides analytical equations and explanations on analyzing the experimental data Describes the most advanced techniques, AFM (Atomic Force Microscopy), SFA (Surface Force Apparatus) in detail

Excerpt from The Use of Colloids in Health and Disease The subject with which this book is concerned is one of vast extent and enormous importance. It covers wide tracts of territory in physiology and medicine. All life processes, as Prof. Wolfgang Ostwald has summarily said, take place in a colloidal system, and that is true both of the normal fluids and secretions of the organism and of the bacterial toxins, as well as, in large measure, of the reactions which confer im munity. If this is so, it would seem to be an obvious desidemtum that the drugs employed to combat disease should be in the colloidal state, i.e. In a form in which they may be isomorphic and isotonic with the elements of the body. Only so can they be expected to exert their full potency. The task of thus bringing their remedial virtue to its highest point is not an easy one, for colloidal substances, unless prepared with consummate skill and meticulous care, lack stability, and are prone to precipitation when brought into contact with the electrolytes normally present in the body tissues and fluids. That it is not beyond the resources of scientific chemistry is clearly shown in this book. A measure of success has, in fact, been achieved which leaves no doubt of the brilliant future which lies before drugs in the colloidal form.
