Abstract:
A microfluidic circuit element comprising a microfluidic main channel and nano interstices is disclosed. The nano interstices are formed at both sides of the main channel and are in fluid communication with the main channel. The nano interstices have a height less than that of the main channel, gives more driving force of the microfluidic channel and provides stable flow of a fluid. The microfluidic circuit element may be made from a plastic material having a contact angle of 90 degrees or less. The microfluidic circuit element is particularly useful when filling a liquid sample to the channel which is empty or filled with air and shows greatly improved a storage stability.

Claim (Index 1):
A method for fabricating a microfluidic circuit element, comprising joining a first plastic substrate and a second plastic substrate, wherein at least one of the first plastic substrate and the second plastic substrate has a groove formed on their facing surface, such that the groove to serve as a microfluidic main channel which has an inlet and an outlet for a liquid sample to flow therethrough,\n wherein the longitudinal axis of the microfluidic main channel is defined as the direction of the flow of the sample, wherein said microfluidic main channel has a height of 5 \u03bcm-2 mm, and a width of 100 \u03bcm-20 mm, wherein an aspect ratio of the width to the height is 10-2000; wherein the microfluidic circuit element further comprises nano interstices formed along with the microfluidic main channel at both sides lateral with respect to the longitudinal axis of the microfluidic main channel, wherein the nano interstices are in fluid communication with the microfluidic main channel though the entire length of the microfluidic main channel; wherein the joining is carried out by applying a bonding agent only to the peripheral regions of the facing surface of the first and second plastic substrates to form a space between the facing surfaces of the first and second plastic substrates, said space defining the nano interstices; wherein the height of the nano interstices ranges from 100 nm to 5 \u03bcm and the width of the nano interstices ranges from 100 \u03bcm to 3 mm; and wherein the plastic substrates have a static contact angle of 40-90 degrees.
