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

open access: yesAdvanced 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 ...

4D–Printed Photothermally Actuated Soft Microgripper on an Optical Fiber Tip for Biomedical Applications

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...
