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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

In-vitro effects of biochemical factors on trypsin activity from intestine and pyloric caeca of common kilka (Clupeonella cultriventris caspia) for inhibition of belly bursting

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
The in-vitro effects of biochemical factors on trypsin activity from intestine and pyloric caeca of common kilka (Clupeonella cultriventris caspia) was evaluated. Trypsin is known to cause belly bursting in common kilka.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Structured Light Projection Using Image Guide Fibers for In Situ Photo‐biofabrication

open access: yesAdvanced Materials, EarlyView.
Light‐based biofabrication is typically performed with single wavelength light sources and within benchtop devices. This work demonstrates FaSt‐Light (Fiber‐assisted Structured Light) as a new approach to achieve multiwavelength image projection using flexible image guide fibers, which enables a variety of applications for in situ biofabrication ...
