Rapidly ageing societies in developed countries demand innovative solutions for future health care systems. Telemedicine, e-health and personalized medicine will successfully address these future challenges. However, to really achieve a fundamental breakthrough in this direction, the development of highly sensitive, miniaturized, easy-to-use, and cost-effective sensor systems for Point-of-Care (PoC) diagnostics is indispensable. At AIT, our interdisciplinary team of chemists, physicists, biologists, and electrical engineers adopts a systemic approach to develop diagnostic sensor system concepts for PoC, delivering solutions that perfectly meet our customers’ application needs.

Sensor Development

Next generation point-of-care (PoC) diagnostic tools will heavily rely on highly miniaturized systems for the detection of the relevant analytes.

AIT‘s Molecular Diagnostics specialists are committed to develop highly sensitive sensors for analyzing body fluids and tissues using innovative photonic, electrochemical, magnetic and nanomaterial-based methods. Our developments are suitable for cost-effective mass production and use environmentally compatible materials in manufacturing and disposal.

In particular, AIT has extensive expertise in the development and fabrication of sensors based on electrochemical sensor structures, e.g. using inkjet printing and paper-based concepts, nanoparticle-based methods, integrated optical waveguides, or magnetoresistive sensor layers (GMR and TMR). Our primary aim is to achieve optimal performance of the sensor system using state-of-the-art methods in simulation and physical modelling. Furthermore, AIT owns a solid competence in elaborating dedicated strategies for the chemical modification of the sensor surface.

With the profound know-how of our interdisciplinary team, AIT is your partner of choice when it comes to solving complex sensor challenges.
