Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

Advanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Multi‐scale Engineered Vasculature and Hierarchical Porosity via Volumetric Bioprinting‐Guided Photopolymerization‐Induced Phase Separation

Advanced Materials, EarlyView.
Vascularization in bioprinted hydrogels is limited by nanoscale porosity in hydrogel bionks. Volumetric bioprinting of gelatin–norbornene phase‐separating hydrogels permits to create centimeter‐scale constructs featuring interconnected multi‐scale porosity. Light dose gradients result in spatially controlled pore dimensions. Capillary‐scale vessels are

Cancer Cells Traverse Faster in Confined Space by Modifying Vimentin filaments With Nuclear Deformation and Promoting the Growth of Desired Tumor Spheroids

Advanced Materials Interfaces, EarlyView.
This study demonstrates how the Vimentin intermediate (VIM) filaments distribution/density regulates the attainment of different migration modes through cytoskeleton rearrangement and controls the nuclear morphology in migrating cells under physical confinement, which facilitates the faster traversing of those cells and the growth of post‐migration ...

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

Exosomes From Intestinal Epithelial Cells Promote Hepatic Differentiation of Liver Progenitor Cells in Gut‐Liver‐on‐a‐Chip Models

Advanced Science
Hepatic progenitor cells (HPCs) are frequently overactivated, and their differentiation into hepatocytes is impaired in advanced liver diseases. To explore the effects of intestinal epithelial cells and their exosomes on the hepatic differentiation of ...

Microwave‐Assisted Aqueous Synthesis of Gelatin‐Norbornene for Hydrogel Crosslinking and Bioprinting

Advanced Materials Technologies, EarlyView.
A microwave‐assisted reaction is utilized to synthesize gelatin‐norbornene (GelNB), achieving a high degree of norbornene functionalization while reducing the macromer's upper critical solution temperature. The resulting GelNB macromer has high solubility at room temperature, facilitating light‐based 3‐dimensional (3D) printing of thiol‐norbornene ...

Advanced Mounting Technique for Improved Imaging and Analysis of Embedded Spheroids and Migrating Cells in Light Sheet Fluorescence Microscopy

Advanced Materials Technologies, EarlyView.
A novel sample holder compatible with the Zeiss Lightsheet 7 microscope improves imaging of spheroids embedded in collagen matrices. By enabling dual‐sided illumination, it enhances image quality and quantitative analysis of migrating cells. This method advances 3D light sheet microscopy for studying tumor invasion and therapeutic responses.
