Honey, I Shrunk the Lab! 

ABSTRACT:

Microfluidic systems promise solutions for high throughput and highly specific analysis for biology, medicine and chemistry while consuming only tiny amounts of reactants and space. On these so-called lab-on-a-chip (LOC) platforms, often multiple physical effects such as electrokinetic, acoustic or capillary phenomena from various disciplines are exploited to gain the optimal functionality. The fluidics on these small length scales differ significantly from our experience of the macroscopic world. In my lecture, I will lay out the fundamentals and basics of the rapidly developing field of microfluidics, discuss the pros and cons and make the audience familiar with the ups and downs. Then, I will survey some of the present approaches and techniques to handle minute amounts of fluid volumes in microfluidic systems with special focus on surface acoustic wave driven fluidics - a technique developed in our laboratory. Here, I will again outline the fundamentals and basics of the technique and demonstrate, for example, how acoustic mixing, fluid actuation and combination of various approaches is realized. Finally, I will discuss its usefulness for several applications ranging from simple mixing tasks over fluid actuation for the realization of complex chip assays and biophysical applications involving cell manipulation etc.
