Abstract
A biosensor with improved detection sensitivity of a target substance, a method for preparing a biosensor with improved detection sensitivity, and a method for detecting a target substance using the biosensor.
Claims10
A biosensor comprising:
- a base material;
- a support layer formed on a first side of the base material;
- and
- a first antibody immobilized in the support layer,
- wherein the support layer formed on the first side of the base material is a self-assembled monolayer formed by a vapor deposition method.
2 more elements
A method for preparing a biosensor comprising:
- forming a support layer, which is a self-assembled monolayer, on a first side of a base material by a vapor deposition method;
- and
- subsequently immobilizing a first antibody in the support layer.
A method for detecting a target substance comprising:
- contacting a test subject substance comprising a target substance, a substrate, and a second antibody in which an enzyme reacting with the substrate is immobilized, with a biosensor including a base material, a support layer formed on a first side of the base material, and a first antibody immobilized in the support layer, wherein the support layer formed on the first side of the base material is a self-assembled monolayer formed by a vapor deposition method;
- and
- measuring changes in the substrate in contact with the biosensor.
