Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

Advanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

Advanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Gold Nanoclusters as Dual Agents for Engineering Tumor Vascular Leakiness and Performing Photothermal Therapy

Advanced Functional Materials, EarlyView.
Many cancer nanotherapeutics, while potent, suffer from the inability to escape from the tumor vasculature, especially in the absence of endothelial permeability. In this work, ultrasmall gold nanoclusters could engineer nanomaterials induced endothelial leakiness (NanoEL) and harness strong NIR induced photothermal characteristics to suppress tumor ...

Carbon Contacts to Proteins Enable Robust, Biocompatible Electronic Junctions with Near‐Activation‐less Conduction Down to 10 K

Advanced Functional Materials, EarlyView.
A robust solid‐state protein junction with a semi‐transparent eC/Au electrode allows photoexcitation of the bacterio‐rhodopsin, bR layer, to isomerize the bR retinal. The resulting photo‐response shows the protein is functional in the solid‐state junction.
