Presentation

Jean M. Feugang is research professor of the Department of Animal and Dairy Sciences at Mississippi State University, USA. His research is focused on the development of bioimaging techniques to improve our knowledge of reproductive biology. The recent progress in nanotechnologies has attracted his attention and instead of nanoparticles being considered just as toxic agents, he sees them as becoming probes available for many uses in reproductive medicine. Nanoparticles measure less than 100 nanometers but have high surface/volume ratios which makes them ideal molecules for high-throughput biomedical applications. Since they are sinthesized from different materials (both inorganic and organic) under different forms they have interesting physical and chemical properties (magnetic and optic) which make them ideal for different applications in reproductive medicine.

In Dr Feugang's laboratory, the use of the properties of these nanoparticles is of major interest to improve medically assisted procreation results. Several nanoparticles including both magnetic and fluorescent types, are currently being used as fasteners with specific (bio)molecules in order to permit the selection of targeted cells or imaging. These conjugated nanoparticles are used for noninvasive applications on sperm after collection to improve performances and bacterial culture to reduce resistance to medicine. The seminar will summarize the recent reports on nanoparticles in the reproductive biology field and will provide an update on our laboratory's studies in this new field.
