Development of Artificial Sebaceous Gland‐Integrated In Vitro Human Skin Model

Advanced Materials Interfaces, EarlyView.
Uniform 3D artificial sebaceous gland spheroids, termed SebaSpheres, are generated at high throughput using a microfluidic platform and structurally integrated into a collagen‐based skin construct containing fibroblasts and keratinocytes. This work presents a modular and scalable fabrication and integration strategy for incorporating sebaceous gland ...

Multiplexed Luminal Tissue Constructs with Reconfigurable Barriers for Dynamic Modeling of Multi‐Tissue Interactions

Advanced Materials Technologies, EarlyView.
This study describes the fabrication of arrays of luminal tissue constructs for 3D luminal tissue modeling. An oil or media‐filled reservoir between constructs serves as a liquid barrier or bridge to regulate communication between lumens within the array for modeling multi‐tissue interactions in vitro. Abstract Cell‐lined luminal structures are crucial

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

Advanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...
