Hygiene: "The sensor applies the principle of so-called photonic structures"

Interview with Prof. Holger Schönherr, Department of Physical Chemistry, University of Siegen

Detecting infections quickly and reliably with the naked eye: This is what many doctors in hospitals and in the doctor's surgeries wish for. To make this dream come true, Prof. Holger Schönherr, a scientist from Siegen, is researching a sensor that should show an infection by a color change.

Green turns to red: with a color change, a nanoporous silicon photonic sensor indicates air exchange in the nanopores with alcohol. In the future, infections are meant to be indicated based on the same principle; ©H. Schönherr et al.
