Abstract: Provided is a method for bonding panel of a microfluidic element by using a releasing film including preparing a panel having a pattern for a microfluidic channel formed on one surface thereof, preparing a release film coated with silicon nanoparticles on one or both surfaces thereof, plasma-treating one surface of the panel on which the pattern for the microfluidic channel is formed and the surface of the release film, and bonding the panel and the release film by performing heat treatment at a predetermined temperature range in a state in which the plasma-treated panel and the release film are attached to each other.

Abstract: A disposable flow velocity measuring device including: a first panel having a flow velocity measuring structure, and having additional micro protrusion patterns formed around the flow velocity measuring structure; a second panel separated from the first panel, and including a fluid channel through which a sample passes; a porous ultra-thin film formed on a portion, at which the first panel and the second panel come in contact with each other, so that the sample passing through the fluid channel does not directly come in contact with the flow velocity measuring structure, thereby separating the first panel and the second panel and removing micro-air bubbles included in the fluid passing through the fluid channel; a non-porous ultra-thin film formed in a partial region of the porous ultra-thin film; and a negative pressure forming unit for applying negative pressure in order to adsorb the first panel and the second panel.

Abstract: Provided is a microfluidic device capable of removing microbubbles in a channel by using a porous thin film, the microfluidic device comprising: an upper panel comprising a microfluidic channel through which a fluid passes; a porous thin film attached to the bottom surface of the microfluidic channel so as to remove microbubbles included in the fluid that passes through the microfluidic channel; a lower panel contacting the bottom surface of the porous thin film and the upper panel, a path being provided in the lower panel so as to discharge microbubbles, which pass through the porous thin film, to the outside; and a vacuum-suctioning means for vacuum-suctioning the upper panel and the lower panel such that the microfluidic channel, to which the porous thin film is attached, is attached to the lower panel in a vacuum state.
