My watch list


Dipl. Ing. Sonja Mülhopt

Karlsruher Institut für Technologie (KIT), Institut für Technische Chemie

Dipl.-Ing. M.Sc. Sonja Mülhopt

Sonja Mülhopt earned her diploma in mechanical engineering at the Berufsakademie Mannheim (now DHBW) in 2000, completing her concomitant training at the Karlsruhe Research Center, now the Karlsruhe Institute of Technology (KIT). In 2014 she received the Master of Science in Chemical Engineering from the University of Mannheim.


Since 2000 Sonja Mülhopt has been working at the Institute for Technical Chemistry (ITC) of the KIT, focusing on the development of bioassays that expose the air-liquid interface to aerosols from technical processes. As head of the working group, she uses her developments and know-how for collaboration projects in Germany and Europe, some of which have been completed. She currently participates in the NanoCare 4.0 program of Germany’s Federal Ministry of Education and Research (BMBF), investigating thermally treated carbon fibers as part of the CFC-CarbonFibreCycle project.


In addition to prizes for poster presentations at specialist conferences, such as the Nanotox 2018 in Neuss (Germany), she received the 1st Prize for outstanding and innovative achievements in the engineering profession from the Association of German Engineers (VDI) in 2018.


Her research focus is how particle emissions from technical processes affect human beings. To assess the lung toxicity of aerosols, Sonja Mülhopt develops methods and techniques to reproducibly expose cell cultures at the air-liquid interface, with a particular focus on characterizing the aerosol and determining the applied dose on the cell culture surface.


  • Air-liquid interface exposure of human lung cells towards inhalable aerosols
  • Dosimetric methods for laminar streaming on biological interfaces
  • Aerosol measurement techniques: mobility spectrometry, optical particle counting, gravimetry, picture analysis of microscopic images (digital microscopy, SEM, TEM)

    Analytical quantitation of gluten in foods

    According to legislation, foods bearing a gluten-free label must not contain more than 20 mg of gluten per kilogram, which is crucial to ensure food safety for celiac disease patients. Gluten is detected by immunological, genomic, chromatographic and/or mass spectrometric methods, but the c ... more

    Assessing the lung toxicity of air pollutants

    The current debates on driving bans in European cities show not only how important air quality is to the public but also reveal the lack of available methods to directly assess the adverse effects of air pollutants on human health. more
