Outline of Final Research Achievements	Factors controlling Organized stress Micro-fibrilization (OM), a new method to create periodic porous structures using light interference, were analyzed to precisely control the pore size. We have succeeded in printing microfluidic channels by using the ability to fabricate long-range connected porous structures in polymer films. This periodic porous structure has a structural color. By combining the structural color with microfluidic channels, we established a system to measure the refractive index of the solution flowing through the channels. The microfluidic channels with different pore sizes were connected and biomolecules of different sizes were separated at the connection.
