Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Downregulation of motility during stress requires stressosome input in Listeria monocytogenes strain EGD-e

Applied and Environmental Microbiology
Motility genes in Listeria monocytogenes are expressed under saprophytic conditions (30°C or less) but are repressed within the host at 37°C. Motility is costly on cellular resources due to the large molecular structures that need to be synthesized, and ...

Aqueous films limit bacterial cell motility and colony expansion on partially saturated rough surfaces.

, 2010
Bacterial motility is a key mechanism for survival in a patchy environment and is important for ecosystem biodiversity maintenance. Quantitative description of bacterial motility in soils is hindered by inherent heterogeneity, pore-space complexity and ...

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

Advanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

Revealing hidden moves: Staphylococcus spp. exhibit motility in semisolid media

Microbiology Spectrum
Staphylococcus spp. are generally considered non-motile due to the absence of active motility structures. However, Staphylococcus aureus, Staphylococcus xylosus, and Staphylococcus epidermidis have demonstrated passive movement.

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

Advanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.
