    • Professor at the University of Erlangen-Nürnberg since 1980, studied chemistry and received his Ph. D. for a study of fast reactions in non-aqueous solutions at the same university. His interests have moved on to NMR studies of solvent effects on metal complexes and carbenium ions, and in the last five years to sensors, particularly the development of sensor materials.

Abstract

Sensors for a huge variety of detection tasks can be made by combining chemically sensitive materials with microstructured physical devices. How individual analyte species can be recognized using host–guest binding schemes (the Figure shows a paracyclophane host molecule) and how categories of compounds can be identified using sensors that respond to different functionalities are reviewed.
