Claim:
1. A method for manufacturing microfluidic chips having at least one capillary for through-flow of a fluid, the method comprising: (a) providing a starting material; (b) forming at least one shared capillary in the starting material, said shared capillary comprising a fluidic inlet and a fluidic outlet, wherein multiple rows of chips are connected to the fluidic inlet and the fluidic outlet, each row of the multiple rows of chips comprising multiple chips that are mutually connected; (c) functionalizing the at least one shared capillary of the chips by supplying a functionalization fluid to the at least one shared capillary; (d) dividing the starting material into separate chips, wherein each of the chips has a functionalized capillary comprising a part of the shared capillary; and (e) removing from at least some of the separate chips portions comprising connecting parts of the at least one shared capillary that mutually connect the multiple rows.
