Patent ID: 8192980

Claim:
A microreactor substantially elongated in shape and formed on a substantially flat substrate comprising: (i) an inlet or feed channel having deflectors dividing the inlet channel into 2 to 10 channels, (ii) an inlet or feed zone for a flow of fluid, (iii) an active zone comprising means which confer on it a high surface-to-volume ratio consisting of blocks comprising a base on a support connected to a top via a wall that is substantially perpendicular to the plane of said substrate, said blocks being evenly spaced out by 10 to 30 μm between the axes of two successive rows according to a two-dimensional network and defining, between the walls, channels connected to one another and substantially parallel to the longitudinal axis of the microreactor and flow axis, and said blocks having a base or top that can fit within a circle of 1 to 20 μm, (iv) an outlet zone and an outlet or evacuation channel having deflectors dividing the outlet channel into 2 to 10 channels, said zones and channels being in fluid communication in which the flow of fluid is substantially along the longitudinal axis of said reactor, wherein the active zone is a reaction zone comprising at least one enzyme capable of producing a biological or biochemical reaction with at least one substrate for said enzyme, said at least one enzyme being attached to the surfaces of said reaction zone whereby said at least one enzyme reacts with said at least one substrate to create a new compound having a different chemical structure as a reaction product, wherein said reaction product may be obtained at the outlet channel of the microreactor, and wherein said enzyme is chosen from the oxidoreductase class, the lyase class, the isomerase class, or the ligase or synthetase class.
