Reconfigurable Microenvironments Uncover Mechano‐Sensing Timescales and Direct Cell Polarity

Advanced Functional Materials, EarlyView.
A synthetic DNA‐crosslinked cell culture matrix enables control over the mechanical microenvironment surrounding cells. Independent tuning of stiffness and stress relaxation uncovers distinct timescales of mechano‐sensing that regulate cell behavior.

Incidence of plasmid and antibiotic resistance in psychrotrophic bacteria isolated from Antarctic sponges

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
A total of 297 bacterial strains were isolated from five Antarctic sponge species and tested by agarose gel electrophoresis for the presence of plasmid molecules. At least one kind of plasmid was carried by 69 isolates (about 23%).

Harnessing Non‐Covalent Protein–Protein Interaction Domains for Production of Biocatalytic Materials Systems

Advanced Functional Materials, EarlyView.
Non‐covalent protein–protein interactions mediated by SH3, PDZ, or GBD domains enable the self‐assembly of stable and biocatalytically active hydrogel materials. These soft materials can be processed into monodisperse foams that, once dried, exhibit enhanced mechanical stability and activity and are easily integrated into microstructured flow ...

Multifunctional, Flexible and Interactive PVDF Fibers with Tunable Conductivity via CNT Coatings for Sensing and Smart Textile Applications

Advanced Functional Materials, EarlyView.
A two‐step fabrication strategy combines electrospinning with electrophoretic deposition of carbon nanotubes to produce conductive, porous PVDF fiber mats. These flexible composites serve as multifunctional sensors, capable of detecting pressure, motion, respiration, and temperature.

Precision Photothermal Therapy at Mild Temperature: NIR‐II Imaging‐Guided, H2O2‐Responsive Stealth Nanobomb

Advanced Healthcare Materials, EarlyView.
The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,
