Upscaling the Fabrication of Rod‐Shaped Microgels: A Microfluidic Method Combining Step‐Emulsification With Consecutive Droplet Confinement in Parallelized Microchannels

Advanced Materials, EarlyView.
A microfluidic method is presented which enables parallelized fabrication of rod‐shaped microgels, based on step‐emulsification (SE) droplet generation and subsequent droplet distribution and confinement, combined in a single device. Microgel rods are fabricated in parallel at different flow rates based on two light‐mediated crosslinking chemistries ...

Bottom‐Up Engineering of a Human Neuromuscular System for Modeling Activity‐Induced Remodeling, Metabolic Stress, and Endothelial‐Modulated Excitability

Advanced Materials, EarlyView.
Using a bottom‐up approach, we engineered a human neuromuscular microchip to investigate distinct adaptive responses to neural stimulation and metabolic stress. Further integration of endothelial cells revealed their critical role in modulating neuromuscular excitability, establishing a comprehensive neurovascular‐muscular model.
