4UM10 - Microfluidics-put-to-work

MSc specialization course of Mechanical Engineering

Micro-fluidics is the science and technology of manipulating and analyzing fluid flow in sub-millimeter dimensions. It is the key enabling technology for many emerging applications and disciplines, especially in the fields of medicine, environmental sensing, biology, and chemistry. Also in engineering and the physical sciences microfluidic systems are employed in applications such as control systems, heat management, and energy generation. Microfluidics approaches can be used to characterize and even manufacture in a controlled way functional particles based on soft materials. Concrete examples of applications are biosensor devices for molecular diagnostics, polymerase chain reaction chips, in-line water quality sensing, high-throughput screening, controlled drug delivery systems, drug discovery methods, forensic analysis instruments, and so on.

In this course, you will learn about physical principles that play an important role in micro-fluidics, how these principles can be applied in practical applications, and which device manufacturing principles can be used to realize these applications. The emphasis will be on concepts and their practical applications, rather than on scientific in-depth theoretical understanding. All of the principles and concepts will be introduced in a bottom-up approach, focusing on examples of actual application areas already in use today. For each of these applications the relevant design concepts and physical mechanisms are categorized in application domains, so that the relation with practice is immediately evident. Special attention will be given to probing properties of soft materials using microfluidics.

A practical workshop, in the Microfab lab, forms an essential component of the course as well as the examination, aimed at gaining hands-on experience with basic micro-fluidics device manufacturing and testing.
