This book provides a comprehensive, state-of-the-art review of microfluidic approaches and applications in pharmatechnology. It is appropriate for students with an interdisciplinary interest in both the pharmaceutical and engineering fields, as well as process developers and scientists in the pharmaceutical industry. The authors cover new and advanced technologies for screening, production by micro reaction technology and micro bioreactors, small-scale processing of drug formulations, and drug delivery that will meet the need for fast and effective screening methods for drugs in different formulations, as well as the production of drugs in very small volumes. Readers will find detailed chapters on the materials and techniques for fabrication of microfluidic devices, microbioreactors, microsystems for emulsification, on-chip fabrication of drug delivery systems, respiratory drug delivery and delivery through microneedles, organs-on-chip, and more.

Nanoparticle processing places a challenging task to the emerging field of nanotechnology for industrial scale applications. Especially pyrogenic synthesis, which is currently the state-of-the-art technology for inorganic nanoparticles, requires a re-dispersion and desagglomeration of nanoparticles in aqueous or non-aqueous solutions for many applications, i.e. coatings, polymer composites or cosmetics. Hydrodynamic stresses are exerted on particle bonds in high pressure dispersion processes and break nanoagglomerates. The agglomerate size decrease as well as structural changes are studied with cutting-edge methods as photon correlation spectroscopy and small angle x-ray scattering. Agglomerate breakage is related to hydrodynamic stresses, which are assessed locally using computational fluid dynamics. Thus a new insight is given into dispersion processes on the nanoscale.

Encapsulations, a volume in the Nanotechnology in the Agri-Food Industry series,presents key elements in establishing food quality through the improvement of food flavor and aroma. The major benefits of nanoencapsulation for food ingredients include improvement in bioavailability of flavor and aroma ingredients, improvement in solubility of poor water-soluble ingredients, higher ingredient retention during production process, higher activity levels of encapsulated ingredients, improved shelf life, and controlled release of flavor and aroma. This volume discusses main nanoencapsulation processes such as spray drying, melt injection, extrusion, coacervation, and emulsification. The materials used in nanoencapsulation include lipids, proteins, carbohydrates, cellulose, gums, and food grade polymers. Applications and benefits of nanoencapsulation such as controlled release, protections, and taste masking will be explained in detail. - Includes the most up-to-date information on nanoencapsulation and nanocontainer-based delivery of antimicrobials - Presents nanomaterials for innovation based on scientific advancements in the field - Provides control release strategies to enhance bioactivity, including methods and techniques for research and innovation - Provides useful tools to improve the delivery of bioactive molecules and living cells into foods

Emulsions are found in a wide variety of food products, pharmaceuticals, paints, and cosmetics, thus emulsification is a truly multidisciplinary phenomenon. Therefore understanding of the process must evolve from the combination of (at least) three different scientific specializations. Engineering Aspects of Food Emulsification and Homogenization d

Nanomaterials possess astonishing physical and chemical properties. They play a key role in the development of novel and effective drugs, catalysts, sensors, and pesticides, to cite just a few examples. Notably, the synthesis of nanomaterials is usually achieved with chemical and physical methods needing the use of extremely toxic chemicals or high-energy inputs. To move towards more eco-friendly processes, researchers have recently focused on so-called “green synthesis”, where microbial, animal-, and plant-borne compounds can be used as cheap reducing and stabilizing agents to fabricate nanomaterials. Green synthesis routes are cheap, environmentally sustainable, and can lead to the fabrication of nano-objects with controlled sizes and shapes—two key features determining their bioactivity. However, real-world applications of green-fabricated nanomaterials are largely unexplored. Besides, what do we really know about their non-target toxicity? Which are their main modes of action? What is their possible fate in the environment? In this framework, the present Special Issue will include articles by expert authorities on nanomaterials synthesis and applications. Special emphasis will be placed on their impact on the environment and long-term toxicity.
