We have special expertise in the development of highly sensitive and highly selective detection methods for biomolecules in liquid samples such as blood or saliva using innovative photonic, electrochemical, magnetic and nanomaterial-based methods. The focus is on the detection of nucleic acids and proteins for point-of-care diagnostics. Our developments are suitable for cost-effective mass production and use environmentally compatible materials in manufacturing and disposal.

Research Services

• Sensor development: Our developments focus on highly sensitive biosensor components for integrated lab-on-chip systems in medical diagnosis. The technologies used range from electrochemical sensor structures, e.g. using inkjet printing and paper-based concepts, nanoparticle-based methods, magnetoresistive sensor layers (GMR and TMR), through to integrated optical waveguide elements. Our primary aim is to achieve optimal performance of the sensor system using state-of-the-art methods in simulation and physical modelling. 
• Surface functionalisation & electrochemical detection methods: Development of surface functionalisation protocols and electrochemical detection methods for specific target molecules and liquid samples. We use signal enhancement mechanisms to achieve maximum sensitivity and short measurement times.
• Sensor system development: Implementation of miniaturised and automated sensor systems with fluidic control and readout units. Special emphasis is placed on user-friendliness.
• Micro & Nanotechnologien: The AIT Center for Thin Film Technology, which specialises in the integration of different materials and components, is the central unit for demonstrator production. It develops functional thin films and coatings using the opportunities offered by micro and nanotechnology for devising and implementing innovative concepts and systems for biomedical diagnostics, lab-on-chip components and sensors.
