<p>A microfluidic floating block comprises: combining grooves for connecting between the multiple microfluidic floating blocks; raised carving and/or depressed carving forms which induce connection between the multiple microfluidic floating blocks and prevent breakaway; floating channels which are the paths of the microfluid; and a sealing unit which is located at the end of the floating channels and prevents leakage of the microfluid when connecting with the multiple microfluidic floating blocks. Also, combining pins for connecting between the microfluidic floating blocks have a structure corresponding to a shape of the combining groove for connecting with the microfluidic floating blocks. The combination achieved by the connection of the microfluidic floating block and the combining pin can freely determine the connection direction of the floating blocks according to the intention of a user. In other words, connection of the fluidic channels and lamination of the floating blocks in a Z-axis direction can be freely formed, and a raised carved and/or depressed carved circular cone structure formed on the outer surface of the floating block provides an automatic location arrangement and location fixing functions between the floating blocks. In addition, the present invention simply controls and changes the floating of microfluids using the microfluidic floating blocks and sealing unit, thereby being able to be used in various forms, including a protein chip, a DNA chip, a drug delivery system, a microbiology/chemistry analysis system, a bioreactor, and the like.</p> |
