Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

open access: yesAdvanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

A Modular Liver–Microbial Microfluidic Platform to Evaluate Therapeutic and Adverse Effects of Microbial Metabolites

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a modular microfluidic platform that connects liver cells with live microbes to mimic key aspects of the gut–liver interaction in steatosis. Using this system, both microbial metabolites and live bacteria significantly reduced fat accumulation in liver cells, but live microbes triggered inflammation and broader metabolic changes ...

A 3D‐Printed Vascular‐Like Perfusion Tumor‐on‐a‐Chip Recapitulates High‐Grade Breast Cancer With in Vivo‐Relevant Drug Resistance

open access: yesAdvanced Healthcare Materials, EarlyView.
A high‐resolution 3D‐printed tumor‐on‐a‐chip platform sustains breast cancer tissues at in vivo–like cell densities through vascular‐like perfusion. This engineered system recapitulates grade‐dependent molecular features and exhibits drug‐resistance profiles that uniquely align with clinically relevant Cmax values.

Evaluation of development performance of port cluster: the case of Yangtze River Delta port cluster

open access: yesFrontiers in Marine Science
Since the last round of government-led provincial port reforms, China’s port clusters have developed rapidly. Despite being China’s most significant port cluster, the Yangtze River Delta (YRD) port cluster faces certain constraints in its development ...

Engineered Microvascular Model of the Blood–Brain–Tumor Barrier Reveals Endothelial Remodeling in Diffuse Midline Glioma

open access: yesAdvanced Healthcare Materials, EarlyView.
We developed a patient‐derived, functional microfluidic model of the diffuse midline glioma (DMG) blood–brain–tumor barrier (BBTB) comprised of endothelial cells, astrocytes, pericytes, and tumor cells. The system forms perfusable microvasculature, reveals the BBTB retains vascular integrity, identifies DMG‐specific transcriptomic changes distinct from

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

open access: yesAdvanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

Waterbirds and human-related threats to their conservation in Laguna Cuyutlán, Colima, México

open access: yesRevista de Biología Tropical, 2009
Laguna Cuyutlán, the only large wetland in a span of 1 150 km along the Pacific coast of México, has been neglected as to its importance for waterbird conservation. At least 25 waterbird species nest there, with some of their colonies being very relevant,
