Abstract
Since the mass-transport phenomenon is quite different in an electrochemical cell setting versus a fluidic-channel setting, it is logical to ask if all the optimization and enhancement discussed in Chaps. 2, 3, and 4 are still applicable to a microfluidic biosensor. This question is better answered by examining the situation in a microfluidic setting. This chapter begins with the development of a fluidic sensor device with microchannel for fluid transport and target detection by multiple microelectrodes made of standing nanopillars. After examining the effects of flow rate, channel height and width, it presents case studies of glucose detection using the developed fluidic sensor device in which all electrodes have their surfaces morphologically modified with nanopillars and its enzyme electrode functionalized using the polypyrrole/GOx method with and without the addition of nanoparticles.
