Abstract Structural and functional compromise of the cellular membrane is a central mechanism in the pathogenesis of numerous diseases, including neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease. However, existing techniques for assessing membrane integrity often lack the ability to provide dynamic, whole-cell measurements and are limited to localized damage detection or population-level analysis.

Loading metrics Open Access Peer-reviewed Research Article Abstract The type VI secretion system (T6SS) is a nanomachine used by many bacteria to drive a toxin-laden needle into other bacterial cells. Although the potential to influence bacterial competition is clear, the fitness impacts of wielding a T6SS are not well understood. Here we present a new agent-based model that enables detailed study of the evolutionary costs and benefits of T6SS weaponry during competition with other bacteria.

Nanowires are presently investigated in the context of various biological and medical applications. In general, these studies are population-based, which results in sub-populations being overlooked. Here, we present a single cell analysis of cell cycle and cell movement parameters of cells seeded on nanowires using digital holographic microscopy for time-lapse imaging.
