Microfluidics And Microscale Transport Processes

The advancements in micro- and nano-fabrication techniques, especially in the last couple of decades, have led research communities, over the world, to invest unprecedented levels of attention on the science and technology of micro- and nano-scale devices and the concerned applications. With an intense focus on micro- and nanotechnology from a fluidic perspective, Microfluidics and Microscale Transport Processes provides a broad review of advances in this field. A comprehensive compendium of key indicators to recent developments in some very active research topics in microscale transport processes, it supplies an optimal balance between discussions of concrete applications and development of fundamental understanding. The chapters discuss a wide range of issues in the sub-domains of capillary transport, fluidic resistance, electrokinetics, substrate modification, rotational microfluidics, and the applications of the phenomena of these sub-domains in diverse situations ranging from non-biological to biological ones like DNA hybridization and cellular biomicrofluidics. The book also addresses a generic problem of particle transport in nanoscale colloidal suspensions and includes a chapter on Lattice-Boltzmann methods for phase-changing problems which represents a generic particle based approach that may be useful to address many microfluidic problems of interdisciplinary relevance.

In this book, the fundamentals of chemical engineering are presented with respect to applications in micro system technology, microfluidics, and transport processes within microstructures. Special features of the book include the state-of-the-art in micro process engineering, a detailed treatment of transport phenomena for engineers, and a design methodology from transport effects to economic considerations.

An investigation was conducted to examine the dominant fluid transport physics at the macro, micro, and molecular scale. Three novel techniques were developed to elucidate the fluid flow fields occurring in microscale and nanoscale fluidic systems. These techniques were then used to design and investigate a novel free-surface microfluidic system capable of delivering sustained and controlled flows ranging from 0 -- 1000 mum/s. The microsystem was then used to develop a sensitive and selective chemical detector capable of identifying certain gas-phase molecules present in the nearby atmosphere. The detector performs molecular recognition of gaseous compounds in the adjacent atmosphere by surface enhanced Raman spectroscopy and the transport properties of the microfluidic system are designed to maximize vapor detection capability. Chemical detection sensitivity of gaseous compounds is better than PPT. Vapors emanated from some nearby solid compounds are also detected at room temperature, including the gas-phase molecules naturally emitted from the explosive compounds: TNT, TATP, picric acid, RDX; and from narcotic samples such as cocaine.

This text focuses on the physics of fluid transport in micro- and nanofabricated liquid-phase systems, with consideration of gas bubbles, solid particles, and macromolecules. This text was designed with the goal of bringing together several areas that are often taught separately - namely, fluid mechanics, electrodynamics, and interfacial chemistry and electrochemistry - with a focused goal of preparing the modern microfluidics researcher to analyse and model continuum fluid mechanical systems encountered when working with micro- and nanofabricated devices. This text serves as a useful reference for practising researchers but is designed primarily for classroom instruction. Worked sample problems are included throughout to assist the student, and exercises at the end of each chapter help facilitate class learning.
