Abstract
The present disclosure provides a microfluidic device (1) comprising at least one flow channel (21) connecting an inlet opening (22) with an outlet opening (23), and an array of wells (24) in fluid communication with the flow channel (21), wherein the flow channel (21) comprises an inlet portion (211) at the inlet opening (22), an outlet portion (212) at the outlet opening (23), and a middle portion (213) between the inlet portion (211) and the outlet portion (212), wherein at least the middle portion (213) comprises the array of wells (24) and is provided with a hydrophilic surface, and the flow channel (21) further comprises a transition area (214) provided at least between the middle portion (213) and the outlet portion (212), which transition area (214) is constituted by providing a hydrophobic surface. Furthermore, a method for manufacturing such a microfluidic device is also provided.
