Article Synopsis
- Bacterial motion in porous media is crucial for survival and applications, and the study focused on Escherichia coli in a microsphere-like environment.
- As the density of microspheres increased, bacterial velocity decreased, and directional changes were more frequent due to collisions with the microspheres.
- The research established a link between bacterial trapping and geometric confinement, revealing that while motility remained stable, mobility was significantly impacted by the structure of the porous media.
Joint replacements have become one of the most common orthopedic procedures due to the significant demands of retaining functional mobility. While these procedures are of great value to patients, there are some limitations. Durability is the most important limitation associated with joint replacement that needs to be addressed due to the increasing number of younger patients.

Metal nanoparticles, especially silver nanoparticles (AgNPs), have drawn increasing attention for antimicrobial applications. Most studies have emphasized on the correlations between the antibacterial potency of AgNPs and the kinetics of metallic to ionic Ag conversion, while other antimicrobial mechanisms have been underestimated. In this work, we focused on the surface effects of polydopamine (PDA) coating on the antimicrobial activity of AgNPs.
