In this paper the use of a special class of self assembling protein materials for optical sensor
technology is discussed. These S-layer proteins were reassembled into well defined nanostructures on solid
sensor surfaces. The covalent immobilization of fluorescent dyes onto these protein structures was
investigated. Following this approach a new oxygen sensitive system based on S-layers functionalized with
Pt(II) metalloporphyrin is described. A luminescence lifetime based measurement system for dissolved oxygen
sensing was successfully developed.
