Functional Materials


Functional materials used by themselves or as an integral part of (bio)chemical sensors or sensing systems are of high interest in analytical chemistry applications. The possibility to combine organic and inorganic elements into a single unit is another promising feature.


We have for example demonstrated that the response behavior and selectivity of a lithium ion-selective optical sensor can be modulated by the pore size of mesoporous silica thin films.


An example for a combination of organic and inorganic elements into a new functional material is a Gd3+-based inorganic particle coated with an organic layer, which has been applied as a hybrid magnetic resonance imaging (MRI) contrast agent for cancer imaging.

In a  different approach, we have converted a photochromic compound into a MRI traceable micellar drug carrier model system that is able to release its molecular load upon irradiation with UV light.
