Embodiment Construction

[0098] The following will refer to figure 1 A fluidic device 100 according to an exemplary embodiment of the present invention is explained.

[0099] figure 1 A cross-sectional view of a fluidic device 100 as a gel electrophoresis device is shown.

[0100] The fluidic device 100 includes a glass substrate 101 in which a groove 102 is formed, for example by etching. A gradient gel strip 103 is disposed on the glass substrate 101 as a fluid transport medium to define a transport path for the electrically driven transport of the fluid sample 104 .

[0101] The majority of the transport medium 103 is arranged on the planar surface of the substrate 101 by printing, although the middle portion of the transport medium 103 is also placed in the groove 102 . Therefore, the transportation medium 103 is along the side wall of the transportation medium 103 (at figure 1 not visible in ) is not supported by the side of the substrate 101.

Abstract

The invention relates to a non-channel fluid sample conveying medium. A fluid control piece (100) comprises a substrate (101) and a conveying medium (103), wherein the conveying medium (103) is arranged on the substrate (101) to define conveying passage for conveying a fluid sample (4) driven by an external force.

Description

technical field [0001] The present invention relates to fluidic devices. Background technique [0002] In microstructural technology applications, fluids can be transported through miniaturized channels (the miniaturized channels can be filled with colloidal materials) formed in the substrate. In the case of capillary electrophoresis devices for the application of this microstructure technology, it may be necessary to generate an electric field in the fluid channel in order to allow the various components of the fluid to be transported through the channel by means of electricity. This electric force or electric field is typically generated by immersing a contact pin of the capillary electrophoresis device in a fluid that can be filled into a well defined by a carrier element coupled to the microfluidic chip and applying a voltage to this contact pin. [0003] US 6,509,085 B1 discloses providing a laminate with channel structures arranged between the plates of the laminate. ...
