Research interests
My research interests center on:
- Understanding the impact of some factors on the behavior of mammalian and microbial cells. I focus on changes in Nano-mechanical properties of cells and in their membrane nanostructure. We mainly use AFM, TEM and SEM. For AFM, we developed a technique to image live microbial cells with different sizes and shapes, and with high resolution.
- Single-molecule and single cell force-spectroscopy measurements using AFM. This topic is one of our main interests. In our current research, we investigate the physical nature of interactions between some molecules, such as hestatin proteins, and surfaces, in particular dental surfaces, under different physiological conditions by functionalizing the AFM tip with the molecule of interest. Also, the measurements of identifying the molecules responsible for interactions between two different microbial species are carried out in our lab.
- The use of nanoparticles as a promising therapeutic approach in dental biofilms treatment.
