Digital Microfluidics With Pressure-Based Actuation [PDF]
IEEE Photonics Technology Letters, 2013 One of the key issues in biosensors is the time it takes for biomolecules in a solution to reach and bind to the sensor surface (particularly in low-concentration analytes). We present a novel flow scheme without microfluidic channels for label-free biosensors to decrease the delivery time of biomolecules.
