SURFACE-FUNCTIONALIZED OPTICAL ELEMENT

原文（中国語）

The invention is directed to a surface-functionalized optical element comprising an IR-transparent optical element, wherein at least a part of the surface of the IR-transparent optical element is covalently bound to a molecular probe by a linker construct. The linker construct comprises a surface attachment moiety, and a spacer moiety which comprises a poly(alkylene oxide). The invention further relates to a process for preparing said surface-functionalized optical element, to an optical biosensor comprising said surface-functionalized optical element, and to a method for detecting a target analyte which uses said surface-functionalized optical element.
