Research interests

My research interests center on:

  • Developing some biosensors in different fields using  mechanical and Nanotechnology-based approaches.
  • Understanding the impact of mechanical properties 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 and diagnostic approach.
