Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Nanodiamond Quantum Sensors for Probing Free Radical Biology

Advanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation

Advanced Functional Materials, EarlyView.
We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

Self‐Assembled Nanoclay Gel With Spheroid MSC‐Derived Exosome Mimetics to Integrate Demineralized Bone Matrix and Noggin‐Targeting miRNA for Synergistic Osteogenesis

Advanced Functional Materials, EarlyView.
We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...
