Abstract: A coil component is provided. The coil component includes a body having fifth and sixth surfaces opposing each other, first and second surfaces respectively connecting the fifth and sixth surfaces of the body and opposing each other, and third and fourth surfaces respectively connecting the first and second surfaces of the body and opposing each other in one direction, a recess disposed in an edge between one of the first and second surfaces of the body and the sixth surface of the body, a coil portion disposed inside the body and exposed through the recess, and an external electrode including a connection portion disposed in the recess and connected to the coil portion, and a pad portion disposed on one surface of the body. A length of the pad portion in the one direction is greater than a length of the connection portion in the one direction.

Abstract: A substrate for immobilizing a physiological material is provided. The substrate comprises a substrate material; a primer layer formed on the substrate material; and an immobilization layer formed on the primer layer. The primer layer is capable of enhancing the attachment between the substrate and the immobilization layer. The substrate for immobilizing a physiological material can provide the immobilization layer with a stable, uniform, and high density through a simple process.

Abstract: The present invention provides a silane oligomer for immobilizing a physiological material that is prepared by copolymerizing an aminosilane compound with a cyclic siloxane oligomeric compound. The present invention can preserve the immobilization layer by applying a silane oligomer. Further, the immobilization layer has a three-dimensional structure and thus has superior thermal stability and reagent resistance.

Abstract: The present invention provides a silane oligomer for immobilizing a physiological material that is prepared by copolymerizing an aminosilane compound with an alkylsilane oligomeric compound. The present invention can preserve the immobilization layer by applying a silane oligomer. Further, the immobilization layer has a three-dimensional structure and thus has superior thermal stability and reagent resistance.

Abstract: A method for preparing a patterned substrate for immobilizing a physiological material is provided. The patterned substrate comprises a primer layer formed on a substrate for controlling surface tension of the upper layer of the immobilization layer, wherein the primer layer has reactive groups to bind an immobilization functional group and hydrophobic functional groups and thus is capable of providing a functional group pattern. The substrate for immobilizing a physiological material can provide the immobilization layer with a stable, uniform, and high-density functional group pattern through a simple process.
