Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

Advanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

Single Enantiomer of YK-4-279 Demonstrates Specificity in Targeting the Oncogene EWS-FLI1

OncoTarget, 2012
Oncogenic fusion proteins, such as EWS-FLI1, are excellent therapeutic targets as they are only located within the tumor. However, there are currently no agents targeted toward transcription factors, which are often considered to be 'undruggable.' A ...

Quadruple Helix Inversions of Liquid Crystals Orchestrated by Direct Chirality Transmission of an Intrinsically Chiral Light‐Driven Molecular Machine

Advanced Materials, EarlyView.
A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft

Dynamic Chiral Plasmonic Systems‐Based on Spiropyran Derivatives and Gold Nanorods

Advanced Materials Interfaces, EarlyView.
Soft chiral plasmonic nanocomposites are prepared by embedding gold nanorods into spiropyran‐based supramolecular gels. The system self‐assembles into helical structures, enabling plasmonic circular dichroism. When illuminated with UV light spiropyran–merocyanine isomerization occurs, inducing reversible nanoscale reorganization and modulation of the ...
