ABSTRACT
Micro-and nanofluidics primarily encompass the fundamental principles and applications concerning fluid flow and transport processes in conduits having at least one characteristic dimension in micro-nano scales (Eijkel and van den Berg, 2005). Over such length scales, extremely large surface area-to-volume ratios of the devices may give rise to intriguing
