High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks

Advanced Materials, EarlyView.
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening

Advanced Materials, EarlyView.
Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

Advanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces

Advanced Materials Interfaces, EarlyView.
Modern biosensors offer high sensitivity but often struggle with long‐term stability and selectivity for specific targets. Antifouling polymer brushes help enhance both stability and selectivity. In this review, we compare recent antifouling coatings, their design parameters, and how they are integrated with biorecognition elements for improved ...

The invertebrate Caenorhabditis elegans biosynthesizes ascorbate. [PDF]

, 2015
l-Ascorbate, commonly known as vitamin C, serves as an antioxidant and cofactor essential for many biological processes. Distinct ascorbate biosynthetic pathways have been established for animals and plants, but little is known about the presence or ...

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

Advanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

Identification of Quorum-Sensing Molecules of N-Acyl-Homoserine Lactone in Gluconacetobacter Strains by Liquid Chromatography-Tandem Mass Spectrometry

Molecules, 2019
Many Gram-negative bacteria can regulate gene expression in a cell density-dependent manner via quorum-sensing systems using N-acyl-homoserine lactones (AHLs), which are typical quorum-sensing signaling molecules, and thus modulate physiological ...
