Modeling of the Van Der Waals Forces during the Adhesion of Capsule-Shaped Bacteria to Flat Surfaces

A novel model is developed to evaluate the van der Waals (vdW) interactions between a capsule shaped bacterium (P. putida) and flat minerals plates in different approach profiles: Vertically horizontally. comparison of approaches well-developed spherical particle mineral surface (semi-infinite wall spherical) has been made this investigation. The interaction potentials for capsule-shaped are found using Hamaker’s microscopic sphere plate cylinder either vertically or horizontally surface. numerical results show that horizontal orientated was more attractive compared approaching vertically. orientation bacterial as well type topology influence adhesion bacteria Furthermore, density difference among each shape (capsule, cylinder, sphere) require amounts energy adhere hematite quartz surfaces.
