Support for a method for determining an analyte and a method for producing the support

A method for producing a support containing polymeric receptors for determining analytes, comprising the steps of

• (a) providing a support, wherein said support comprises a support body comprising at least one channel which comprises a conduit with a top, a bottom and two sides having an inlet and an outlet for passing fluid from the inlet to the outlet, and at least one reaction position in the support body, wherein said support is optically transparent at least in the region of said at least one reaction position,
• (b) placing said support body between a programmable light source matrix and a detector matrix,
• (c) passing liquid with building blocks for synthesizing said polymeric receptors through the channel or channels of the support body,
• (d) site- and/or time-specifically immobilizing the said building blocks on predetermined reaction positions in the channel or channels by illumination of said predetermined reaction positions by said programmable light source matrix, wherein the illumination position of said light source matrix is monitored by computer using said detector matrix, and
• (e) repeating steps (c) and (d) until said polymeric receptors have been synthesized on the predetermined positions.
