A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

Advanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

Advanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

Advanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures

Advanced Materials Technologies, EarlyView.
A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...
