    摘要： 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.

    摘要： Microfluidic Systems, Devices and Methods for Reducing Noise Generated by Mechanical Instabilities. According to one embodiment, a microfluidic device is provided for reducing noise in a fluid mix. The microfluidic device can include microscale channels for passage of fluids to a mixing junction. The mixing channel can be adapted to combine the fluids into a common fluid flow. The microfluidic device can also include a connector channel including first and second ends. The first end of the connector channel can be connected to the mixing junction. The microfluidic device can also include an expansion channel having connection to the second end of the connector channel. The expansion channel can be adapted for passage of the fluid mix through the expansion channel to reduce concentration gradient noise of the fluid mix by dispersion of the fluid mix as the fluid mix passes through the expansion channel.
