    摘要： A fluidic culture device (100) comprises a substrate (101) of transparent polymer material with an open culture chamber (110) in the form of a hollow in a bottom surface (102) of the substrate (101). Open fluid channels (120, 130) flank the culture chamber (110) and have inlets (140, 150) and outlets (160) in a top or end surface (104, 106) of the substrate (101). Removable channel plugs (180, 190) are temporarily arranged in the portions of the fluid channels (120, 130) adjacent the culture chamber (110) to prevent culture matrix material poured into the culture chamber (110) from entering and blocking the fluid channels (120, 130). When assembling an operational culture system (230), a biological sample (210) is introduced in the culture matrix (200) and the channel plugs (180, 190) are removed. A transparent cover disk (220) is reversibly attached to the bottom surface (102) to enclose the culture chamber (110) and the fluid channels (120, 130). A gradient is established over the culture chamber (110) by entering fluids having different concentrations of a substance in the fluid channels (120, 130).

    摘要： A fluidic device (1) has a culture chamber (10) configured to house a 3D culture matrix (2) comprising a culture of microorganisms (6). A concentration gradient of a test substance is established over the 3D culture matrix (2) by providing respective fluid flows at different end portions (12, 14) of the culture chamber (10) and comprising different concentrations of the test substance. The response of the microorganisms (6) to the test substance is determined based on the position of a border zone (5) in the 3D culture matrix (2).
