Microfluidics technology involves systems that manipulate and process small amounts of fluids at the microscale, which has been matured into a multidisciplinary subject that profoundly impacts both scientific research and real-world products. This course is to teach the students who are seeking a degree of Doctor of Philosophy relevant to fluid mechanics, covering an introduction to the fundamental concepts, manufacturing methods, basic classifications, and practical applications of microfluidic systems. The course aims to equip students with knowledge of both fundamentals and applications of microfluidics, with deep insight into various microfluidic systems useful for tackling key issues in multidisciplinary fields such as engineering, chemistry, biology, and medicine, and with skills in analysing and designing microfluidic systems for advanced research and development applications.
