Supercritical Fluids in Pharmaceutical and Biomedical Technologies: From Controlled Drug Release Formulation describes the well-studied, but previously not well summarised supercritical fluid technologies useful for pharmaceutical and biomedical applications. Supercritical technologies have been described over the last 20 years as innovative and capable of solving many problems relating to conventional chemical processes such as extraction, crystallization, foaming, drying precipitation, aerogels fabrications. This is generally true but there remain exceptions and limitations. Featuring extensive case studies and examples presenting from lab-scale to industrial scale, the author highlights the innovations of the described processes, but also their drawbacks, such as the difficulties to generalize the process application to several drugs and biomolecules. The book provides a critical overview on the necessity of process optimization case-by case that have limited the use of these dense gases in larger scale pharmaceutical or biomedical industrial production. Supercritical Fluids in Pharmaceutical and Biomedical Technologies: From Controlled Drug Release Formulation to Tissue Engineering will appeal to graduate and postdoc level students and researchers primarily in chemistry, pharmaceutical chemistry, and chemical engineering. R&D scientists at pharma and biotech companies and postdoc students studying advanced pharmaceutical technologies for drug delivery and tissue engineering, medical biomedical technology and bioengineering will also find the book useful for reference. - Provides a much-needed summary and overview of the use of supercritical fluids in pharmaceutical and biomedical applications - Addresses both the successes and limitations in application of supercritical fluids in this area - Presents several schematic descriptions of supercritical fluid-based processes. - Features a range of pharmaceutical and biomedical case studies and examples from lab-scale to industrial scale, assessing successes and limitations - Provides a critical overview on the necessities of process optimization case-by case that have limited the use of dense gases in larger scale pharmaceutical or biomedical industrial production

Supercritical fluid carbon dioxide (sc-CO2) possesses both gas-like and liquid-like properties. It is capable of depositing nanoparticles in small structures and poorly wettable substrates. Deposition and array formation of metal and metal sulphide nanoparticles on various substrates using sc-CO2 as a medium has been a subject of considerable interest for researchers in nanomaterials area in recent years. This handbook begins by exploring nanoparticle deposition using supercritical fluid carbon dioxide. Further topics in this handbook include separation of oils using supercritical carbon dioxide; the application of an integrated supercritical extraction and impregnation process for incorporation of thyme extracts into different carriers; supercritical fluid extraction application on dairy products and by-products; and supercritical fluid technology applications in pharmaceutical drug formulations.

Advancing with Biomedical Engineering Today, in most developed countries, modem hospitals have become centers of sophis ticated health care delivery using advanced technological methods. These have come from the emergence of a new interdisciplinary field and profession, commonly referred to as "Bio medical Engineering." Although what is included in the field of biomedical engineering is quite clear, there are some disagreements about its definition. In its most comprehensive meaning, biomedical engineering is the application of the principles and methods of engi neering and basic sciences to the understanding of the structure-function relationships in normal and pathological mammalian tissues, as well as the design and manufacture of prod ucts to maintain, restore, or improve tissue functions, thus assisting in the diagnosis and treat ment of patients. In this very broad definition, the field of biomedical engineering now includes: • System analysis (modeling, simulation, and control of the biological system) • Biomedical instrumentation (detection, measurement, and monitoring of physio logic signals) • Medical imaging (display of anatomic details or physiologic functions for diag nosis) • Biomaterials (development of materials used in prostheses or in medical devices) • Artificial organs (design and manufacture of devices for replacement or augmen tation of tissues or organs) • Rehabilitation (development oftherapeutic and rehabilitation procedures and de vices) • Diagnostics (development of expert systems for diagnosis of diseases) • Controlled drug delivery (development of systems for administration of drugs and other active agents in a controlled manner, preferably to the target area)

Globalization and industrialization involve a number of reactions, products, extractions, and separations that require the use of organic solvents. These solvents are responsible for a number of ecological concerns, including atmospheric and land toxicity. Conventional organic solvents are regarded as volatile organic compounds; some are even limited due to their potential for ozone layer depletion. While supercritical liquids exhibit physical properties that could make them ideal substitutes for these volatile compounds, there is particular interest in the use of carbon dioxide as a solvent of crude material. In particular, carbon dioxide has apparent ‘green’ properties, like its noncombustible nature, the fact that it is generally nonpoisonous, and its relative inertness. Thus, the use of supercritical carbon dioxide can provide practical improvements to the sustainability of industrial products and processes. This book provides in-depth literature in the area of industrial green processes, focusing on the separation, purification, and extraction of compounds utilizing supercritical carbon dioxide as a green solvent.

Supercritical fluids are neither gas nor liquid, but can be compressed gradually from low to high density and they are therefore interesting and important as tunable solvents and reaction media in the chemical process industry. By adjusting the density the properties of these fluids can be customised and manipulated for a given process - physical or chemical transformation. Separation and processing using supercritical solvents such as CO2 are currently on-line commercially in the food, essential oils and polymer industries. Many agencies and industries are considering the use of supercritical water for waste remediation. Supercritical fluid chromatography represents another, major analytical application. Significant advances have recently been made in materials processing, ranging from particle formation to the creation of porous materials. The chapters in this book provide tutorial accounts of topical areas centred around: (1) phase equilibria, thermodynamics and equations of state; (2) critical behaviour, crossover effects; (3) transport and interfacial properties; (4) molecular modelling, computer simulation; (5) reactions, spectroscopy; (6) phase separation kinetics; (7) extractions; (8) applications to polymers, pharmaceuticals, natural materials and chromatography; (9) process scale-up.
