Porous PEGDA hydrogels promote hMSC survival and eventual differentiatability

The FASEB Journal, 2009
Superporous poly(ethylene glycol) diacrylate (PEGDA) hydrogel scaffolds have the potential to overcome the problems of difficulty seeding cells into the scaffold. The interconnected pore network of the superporous hydrogels (SPH) not only allows cells to attach to the interior porous structure but also ...

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

3D Printed PEDOT:PSS‐Based Lattice Pressure Sensors With Tunable Electromechanical Response

Advanced Materials Technologies, EarlyView.
poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS)‐based architected lattices are fabricated via single‐step Digital Light Processing (DLP) printing for tunable pressure sensing. Structural design variations allow precise control of sensitivity and range, while integrated conductivity eliminates post‐processing.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

Advanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications

Advanced Materials Technologies, EarlyView.
Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...
