An unexpected use of ferrocene. A scanning electrochemical microscopy study of a toll-like receptor array and its interaction with E. coli.

Abstract

Imaging of toll-like receptor microarrays was achieved using scanning electrochemical microscopy with the successful integration of two ferrocene derivatives in order to enhance the background contrast. This investigation has resulted in the novel fabrication of a tuneable, multiplex, broad-spectrum bacterial sensor for the interrogation of conserved microbial stimuli.
