SUBSTRATE FOR IMMOBILIZING BIOLOGICAL SUBSTANCE AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a substrate for immobilizing a biological substance which comprises a glass substrate containing an alkali component, wherein the elution of the alkali component is prevented and thus a biological substance can be stably immobilized. Specifically disclosed is a substrate for immobilizing a biological substance which comprises a glass substrate containing an alkali component, a sputtered SiO2 film formed on the glass substrate, and a silane coupling agent layer bonded to the sputtered film.
