Abstract:
1. A microfluidic structure for biomedical applications, comprising: a polymer scaffold, suitable for biomedical applications, defining a shape of a first microfluidic channel therein, at least a portion of the first microfluidic channel being characterized by a substantially circular cross section and a gradually changing diameter over a length thereof, wherein for any first diameter of the first microfluidic channel and any second diameter of the first microfluidic channel intersecting the first diameter, where the first diameter is greater than the second diameter, the ratio of the first diameter to the second diameter is between 1.0 and 1.3; wherein the first microfluidic channel bifurcates into at least a second microfluidic channel and a third microfluidic channel, and a diameter of the first microfluidic channel smoothly and gradually transitions to a diameter of the second microfluidic channel and a diameter of the first microfluidic channel smoothly and gradually transitions to a diameter of the third microfluidic channel.
