High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

open access: yesAdvanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...

Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

open access: yesAdvanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Measurement of Glioma Viscoelasticity Using a Handheld Palpation Imitation Device

open access: yes, 2017
We examined glioma tissues immediately after en-bloc removal during surgery and measured elastic modulus, viscosity, and viscoelasticity of the gray and white matter to confirm the feasibility of measurement using an indentation device. Measurements were

The Role of Viscoelasticity in Heterogeneous Glioblastoma Stem Cell Invasion in Biomimetic 3‐Dimensional Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of viscoelasticity in the invasion of heterogeneous glioblastoma stem cells (GSCs) was investigated with GSCs categorized into subgroups based on molecular profile, as Reactive, Invasive, or Constructive using viscoelastic biomimetic hyaluronan‐oxime hydrogels.

Pressure‐Assisted Drug Delivery Using High‐Pressure Balloon Platform Improves Vascular Drug Penetration and Anti‐Restenotic Effects

open access: yesAdvanced Healthcare Materials, EarlyView.
A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the

Hybrid Biofabrication of a Hierarchically Organized Periosteum‐Inspired In Vitro Platform

open access: yesAdvanced Healthcare Materials, EarlyView.
A hybrid biofabrication strategy integrates melt electrowriting with extrusion‐based 3D bioprinting to create a hierarchically organized periosteum‐inspired in vitro platform. Spatially defined osteogenic, fibrous, and endothelial cell‐containing compartments support long‐term culture, osteogenic maturation, and CD31+ endothelial cell organization ...
