The invention relates to a microfabricated valve (10) comprising a first channel (11), a second channel (12) and a connecting channel (13). The connection channel (13) connects the first channel (11) and the second channel (12). The microfabricated valve further includes a valve portion (14) disposed within the link channel (13), the valve portion (14) being adapted to selectively open and close the link channel (13). In addition, the invention provides a method comprising the steps of: inserting the first channel (11) into the first layer (21), inserting the second channel (12) into the third layer (23), inserting the link channel (13) with the valve portion (14) in the second layer (22), and then arranging the second layer (22) between the first layer (21) and the third layer (23). The invention further relates to a test device, in particular for a biological application and in particular a method for performing a biological test cycle. |
