Generally, opto-chemical sensor systems utilize light and optical properties of indicator materials to detect the interaction between sensor and analyte for determining the analyte`s concentration. Here, only the indicator itself interacts with the analyte. Hence, the remote readout systems are not directly in contact with the sample.
Example 1: New and unique opto-chemical sensors were developed based on the technology of electrospinning. Here, an ultra-fine network of polymer nanofibers is created sensor layers with high surface-to-volume ratio. Hence, the sensors show ultra-fast response characteristics and high sensitivity.
Example 2: Sensor textiles were developed by covalently coupling various indicator dyes to textiles and non-wovens. Upon contact with chemical or biological compounds these textiles change color or fluorescence properties indicating the presence or absence of an analyte. The staining process can be directly integrated into existing textile fabrication processes, thereby opening new applications in the field of clothing, healthcare, ambient assisted living, sports and food packaging.

Opto-chemical SENSORs based on nanofibers
The ultra-fast oxygen sensing technology can be implemented in ergospirometric devices. Ergospirometry represents the future in non-invasive medical diagnosis of pulmonary and cardiovascular diseases, training optimization in sports and general fitness applications by means of breath gas analysis.
Sensor materials integrated in industrial protective clothing, for example, warn wearers of the presence of hazardous gases or liquids such as carbon monoxide, ammonia or strong acids in their immediate environment.
Fibres and yarns containing indicator dyes can be used in wound dressings to provide information on the wound healing process with colour changes indicating, for example, changes in oxygen or pH levels or problematic bacterial growth.
Clothing with colour changing properties can also be used to indicate excessive water or electrolyte loss. This can be important in healthcare applications involving the elderly or very young children who may find it difficult to communicate
Currently we have two reference projects within the scope of opto-chemical sensors (1st oxygen sensor and 2nd textile sensor).
- O2 High-Speed: Ultra-fast oxygen detection in exhaled breath gas for ergospirometric devices.
- Smart Colour Textiles: Indicator washcloth and sensor swabs for monitoring pH in wounds
Our researchers specialize in the development and technological implementation of chemical and biological sensors. These are compact analytical systems that allow for continuous monitoring of chemical, metabolic or biological parameters such as, for example, oxygen, glucose or lactate, but also of toxic gases, heavy metals, bacteria and toxins.
The research team is a leader in the development of optical chemical sensors (optodes) and measurement systems used in process control, medical diagnostics, environmental analysis, authentication and food monitoring.
In addition, new materials for screen printing, inkjet printing and aerosol-jet printing of electrode structures, as well as methods for surface functionalization and structuring of polymeric materials for biosensors, are developed.
