On September 12, 2019, professor Mingdong Dong from Aarhus University in Denmark was invited to the Guangdong Institute of Microbiology for academic communication and gave an academic seminar entitled "Nanoscale measurement of material by scanning Probe Microscopy Approach".

       During his talk, professor Dong introduced the classification, development history and principle of scanning probe microscopy, then listed the research results of his team in using this technology to observe various biological samples from environment to human. The research contents mainly included the differences in the mechanical properties of cell surface structure, the folding and assembly rules of macromolecular proteins, etc. In addition, the progress of the research on the electric conduction mechanism of cable bacteria was also covered in his talk, which inspired present teachers and students actively discussed relevant academic issues with professor Dong. Not only students but also teachers benefit a lot from his talk.

       Mingdong Dong is a tenured professor at the University of Aarhus, Denmark and a doctoral tutor. In 1999, he obtained his bachelor's degree in materials science from Central South University. He earned a master's degree in material physics from Chalmers University of Technology in Sweden in 2002, and a Ph.D. in physics from Aarhus University in Denmark in 2006. From then to 2009, he worked as a postdoctoral researcher at Harvard University in the United States. With his outstanding achievements, he received a position at Aarhus University in Denmark and was granted tenure in 2013.

       With his expertise in developing of new scanning probe microscopy and various other surface-sensitive technologies, he applies probe technology to interdisciplinary research fields, covering new materials, physics, chemistry, biology, medicine, etc. The wide use of microscopic method allows him to host and participate in more than 20 projects supported by various foundations, such as the Danish Natural Science Foundation and the European Community Natural Science Foundation. He serves as an expert judge of several national funds in the European Union, Switzerland, and the United Kingdom. He has more than 200 academic publications, including 2 Nature, 2 Nature Nanotechnology, 1 Nature Chemistry, and 3 Nature Communications papers, all of which have high-impact factors. His papers have been cited more than 5,000 times.
