Micro and Nano Fluidic Chips for Biosensors

Micro and nanofluidics provide very controlled delivery of reagents and samples for highly sensitive biosensors. Two fluidic platforms are introduced in this paper, the microfluidic droplet emulsion and the electrical field-based microfluidics. Traditional issues in microfluidics such as mixing in low Reynolds numbers can be mitigated using some of our active microfluidic techniques.
