Abstract: Provided is an apparatus for generating a microfluidic concentration field, the apparatus including: a substrate; a base film disposed on the substrate; a microchannel, which is formed in a space between the substrate and the base film and through which a fluid flows; a through passage, which communicates with the microchannel and is configured to pass through the base film; and a membrane, which is formed at a portion where the microchannel and the through passage communicate with each other and allows the fluid flowing along the microchannel and the through passage or a material flowing together with the fluid to selectively pass through the membrane, wherein a concentration field is formed between the fluid of the through passage and the fluid of the microchannel by the membrane.
