Zero-mode waveguides with non-reflecting walls

摘要

The application relates to improved optical containment structures, methods of manufacture and use, and systems for employing same. The optical containment structures generally comprise zero-mode waveguide structures having non-reflective walls. The non-reflective walls allow the preparation of optical containment regions in which the optical containment dimensions can be decoupled from the solution containment dimensions. The application also relates to methods for producing islands of functionality within nanoscale apertures.

1. A zero-mode waveguide structure comprising:
a) a transparent substrate having a top surface; b) an opaque layer comprising a metal disposed upon the top surface of the transparent substrate; c) an array of apertures extending through the opaque layer to the transparent substrate whereby the apertures comprise wells having walls and bases, the bases of the wells comprising portions of the top surface of the transparent substrate; and d) a non-reflective layer comprising an oxide formed by oxidation of the metal disposed on the walls of the wells wherein the thickness of the non-reflective layer is greater than about 10 nm.
