In this contribution, we review the molecular and physiological barriers to oral delivery of
peptides and nanoparticles. We discuss the opportunities and predictivity of various in vitro …

Mucus hydrogels at biointerfaces are crucial for protecting against foreign pathogens and for
the biological functions of the underlying cells. Since mucus can bind to and host both …

Diverse processes—eg bioremediation, biofertilization, and microbial drug delivery—rely on
bacterial migration in disordered, three-dimensional (3D) porous media. However, how pore …

Mucus is a complex hydrogel that acts as a natural barrier to drug delivery at different
mucosal surfaces including the respiratory, gastrointestinal, and vaginal tracts. To elucidate …

Biofilms, surface-attached communities of bacteria encased in an extracellular matrix, are a
major mode of bacterial life. How the material properties of the matrix contribute to biofilm …

Bacterial biofilms are communities of adhering bacteria that express distinct properties
compared to their free-living counterparts, including increased antibiotic tolerance and …

Polymers are the main constituents of many materials and products in our modern world.
However, their environmental safety is not assessed with the same level of detail as done for …

Understanding how bacteria move in porous media is critical to applications in healthcare,
agriculture, environmental remediation, and chemical sensing. Recent work has …

Bacteria are ubiquitous in our daily lives, either as motile planktonic cells or as immobilized
surface-attached biofilms. These different phenotypic states play key roles in agriculture …

To understand the dynamical and conformational properties of deformable active agents in
porous media, we computationally investigate the dynamics of linear chains and rings made …
