A method for producing a support for determining analytes. The method
comprises the steps of (a) providing a support comprising at least one
channel, comprising a conduit having an intake and an outlet for passing
fluid from the intake to the outlet, in the support body, (b) passing
liquid with building blocks for synthesizing polymeric receptors through
the channel or channels of the support body, (c) site- and/or
time-specifically immobilizing the receptor building blocks in each case
on predetermined positions in the channel or channels by illumination and
(d) repeating steps (b) and (c) until the required receptors have been
synthesized in each case on the predetermined positions.
