From Molecule to Aggregate: Designing AIE Nanocrystals for Low‐Power Backward Third‐Harmonic Generation Angiography

Advanced Materials, EarlyView.
An organic BTHG agent called OTBP with prominent crystallinity is developed. The resonant absorption at 433 nm and prominent crystallinity of OTBP enhance its BTHG efficiency when excited by a 1300 nm femtosecond laser. Tuning the size of OTBP nanocrystals based on Mie scattering theory successfully enables them to achieve high‐contrast muti‐organ ...

Hydrogel‐Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti‐Migration of Esophageal Stent

Advanced Materials, EarlyView.
The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation

Advanced Materials, EarlyView.
Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.

Mitochondrial Transplantation via Magnetically Responsive Artificial Cells Promotes Intracerebral Hemorrhage Recovery by Supporting Microglia Immunological Homeostasis

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
A type of magnetically responsive artificial cells (ACs) has been developed, demonstrating the loading of mitochondria and self‐enclosure processes to ensure the protection of mitochondrial transport via the bloodstream. The treatment with ACs effectively transplanted mitochondria around the lesion, thereby improving neurological recovery by supporting
