Abstract

To generate flow in microchannels, several actuation schemes have been suggested. Capillary driving is widely used in plastic disposable micrlfuidic plaforms due to its simplicity. However general plastics in microfluidics are hydrophobic, which inhibits capillary flow generation and requires surface treatment that easily deteriorate with age. To promote consistency of capillary flow in plastic microchannel, we introduce nano interstices (NI) at the side wall of the microchannel, resulting capillary flow less dependent on surface characteristics. NI flow generation is a useful alternative technique to create long term predictable flow in commercialized microfluidic products.
