Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

Advanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Microspheres

Microspheres are multiparticulate drug delivery systems which are prepared to obtain prolonged the controlled drug delivery to improve bioavailability, stability and to target the drug to specific site at a predetermined rate. They are made from polymeric waxy or other protective materials such as natural, semi synthetic and synthetic polymers ...

Protease‐Triggered Chromogenic Release From Peptide‐Modified Calcium Carbonate Microspheres Enables Colorimetric Detection of Porphyromonas gingivalis Activity

Advanced Science, EarlyView.
We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

Advanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...
