Abstract
Microfluidic Systems, Devices and Methods for Reducing Diffusion and Compliance Effects at a Fluid Mixing Region. According to one embodiment, a microfluidic device is provided for combining fluids in a mixing region. The microfluidic device can include a fluid mixing region connected to a first and second microscale channel. The microscale channels can advance fluids to the fluid mixing region. The microscale channels can include constricted flow portions. According to another embodiment, the microscale channels can be connected to waste channels for removing fluid diffused into one of the channels from the other channel. According to yet another embodiment, a microfluidic system is provided for controlling the flow of fluids through the microscale channels for reducing or eliminating diffusion between the channels.
