Abstract
The present invention provides novel microfluidic devices and methods for preventing/ameliorating formation of precipitate blockages in microfluidic devices. In particular the devices and methods of the invention utilize microchannels of specific cross-sectional configuration and of specific arrangement as well as application of AC current orthogonal to the direction of fluid flow, in order to preventing/ameliorating formation of precipitate blockages in microfluidic devices.
