Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming

open access: yesAdvanced Materials, EarlyView.
Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Mechanically Robust MXene‐Metal Polyphenol Network Hybrid Interfaces for Multifunctional Protection of Keratin Fibers

open access: yesAdvanced Materials Interfaces, EarlyView.
Hair keratin fibers inevitably deteriorate under UV exposure, heat, and dryness. A robust composite coating assembles delaminated Ti3C2 MXene nanosheets onto keratin surfaces through biocompatible metal‐polyphenol networks of EGCG. This hybrid layer simultaneously screens UV, dissipates heat, reinforces mechanical strength, suppresses static charge ...

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Topography‐Regulated Screening Platform for Myoblast Contact Guidance

open access: yesAdvanced Materials Technologies, EarlyView.
This study develops a topography‐regulated screening platform (12 gradients in 96‐topography‐well plate) enabling analysis of skeletal muscle morphogenesis. The topography‐induced cell morphology changed, cell polarization, and myotube differentiation, establishing an evaluative framework for generating pathologically relevant myotube phenotypes to ...

Light‐Driven Quadrupedal Walking Biohybrid Robot With Antagonistic Muscle‐Rings and Inclined Joints

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a light‐driven quadrupedal walking biohybrid robot powered by antagonistic muscle‐rings that achieve alternating walking gait. Optical training improved reproducibility of cultured muscle tissues, while caffeine treatment enhanced contractile force.

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

open access: yesAdvanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

IL‐3 Modulates Microglia Polarization and Attenuates Neuroinflammation in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
IL‐3 recruits PRDX1 through IL‐3R to modulate the inflammatory response of microglia via the KEAP1‐NRF2‐HO‐1/NF‐κB pathway to attenuate neuroinflammation in traumatic brain injury. ABSTRACT Microglia play a crucial role in the progression of neuroinflammation following traumatic brain injury (TBI). Interleukin‐3 (IL‐3), a significant regulatory factor,
