Anti‐Swelling Textile Power Generator with 1D Nanoscale Channel Alignment in Nanofiber/Graphene Hybrid Yarns

Advanced Functional Materials, EarlyView.
A nanofiber/graphene hybrid yarn with 1D oriented nanoscale channel is constructed via bath electrospinning followed by a functionalization process, yielding exceptional anti‐swelling and weaving abilities. When configured into a waterproof fabric through series‐parallel connection of 62‐cm yarns, an output power of 31.96 µW is achieved, which could ...

Engineering Highly Cellularized Living Materials via Mechanical Agitation

Advanced Functional Materials, EarlyView.
A mechanical agitation strategy is developed to engineer highly cellularized living materials, achieving cell densities of up to 1 billion cells per milliliter. By precisely tuning properties such as stiffness and toughness in blood clots, the approach is validated in both in vitro and in vivo studies.

A Bioengineered Model of the Human Cornea for Preclinical Assessment of Human Ocular Exposure to Environmental Toxicants

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper presents a microphysiological system containing an array of individually addressable living corneal tissues constructed using primary human cells. The bioengineered eye model can simulate acute exposure of the human cornea to different types of environmental toxicants and provides a novel platform for visualization and quantitative ...
