摘要 |
<p>A microfluidic device is disclosed comprising a body of refractory material having one or more fluid passages of millimeter-or sub-millimeter scale defined therein and at least one tube of refractory material embedded in said body, the tube having a millimeter-or sub-millimeter-scale passage therein and first and second ends. The tube is desirably, though not necessarily, of a material having a higher softening point than the material of the body. The tube may optionally include a narrowed or "drawn down" portion along the length or at an end thereof to provide extremely fine structure. By shaping depressions or holes to receive the tube in layers of refractory material that are fired or sintered to form the device, the tube can be assembled together with the layers and fired or sintered to form a consolidated refractory microfluidic device. ® KIPO & WIPO 2008</p> |
