Abstract:
A method of forming a plurality of identical miniaturized column devices, comprising the steps of:(a) providing a master support body having a substantially planar interior surface, wherein the master support body is comprised of a material other than silicon and silicon dioxide;(b) forming a master copy of a miniaturized column device by: forming a microchannel directly in the interior surface of the master support body;(c) forming a mold insert by: (i) coating the interior surface of the master copy with a layer of a metal; (ii) depositing a metal thereon to fill the microchannel formed in the interior surface; and (iii) separating the mold insert from the master support body, whereby a mold insert is provided; and(d) preparing additional miniaturized column devices identical to the master copy by filling the mold insert with a suitable polymeric or ceramic material, whereby a miniaturized column device thus formed can be covered with a plate over the microchannel of the additional miniaturized column device to form a device having a microchannel for a fluid to pass therethrough.
