Embodiment Construction

[0045]Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0046]FIG. 1 is a plan view schematically illustrating a microfluidic device according to an embodiment of the present invention. Referring to FIG. 1, the microfluidic device includes a body of revolution 100 and one or more microfluidic structures 101 disposed on the body of revolution 100. According to the current embodiment of the present invention, the body of revolution 100 may be a disk-shaped platform. The platform can be easily manufactured and formed of plastic materials such as an acryl and PDMS and the surface of the platform is deactivated. However, the materials are not limited to the examples above and may be any materials having chemical and biological stability (i.e., inactivity), optical transparency, and mechanical processability. The body of revolution 100 may have a hole at the center thereof....
