Sensor Materials - Detecting Molecules, Mixtures and Microorganisms -

Abstract

Sensor materials based on molecularly imprinted organic and inorganic polymers were designed and characterized according to their selectivity and sensitivity using mass-sensitive quartz crystal microbalances (QCMs). Cavities of differing shapes and sizes were created in both organic and inorganic polymers, able to selectively re-include the template species. Imprinting was performed both on the molecular and the micrometer scale. The chemical and biomimetic sensors developed allow the detection of various analyses, such as VOCs in ambient conditions, complex mixtures (automotive engine oils) and microorganisms. Thus, the extraordinary flexibility of templating methods is proved as the most versatile platform technology for advanced sensor materials.
