A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

Advanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Laser‐Induced HKUST‐1 Derived Porous Electrocatalyst: an Innovative Approach to Boost Sustainable Ammonia Synthesis

Advanced Sustainable Systems, EarlyView.
A zero‐waste, eco‐friendly, binder‐free, scalable, rapid, and one‐pot laser carbonization approach fabricates a coppercuprous oxide/carbon electrocatalyst derived from HKUST‐1 metal‐organic framework for efficient nitrate reduction to ammonia. The catalyst exhibits high ammonia yield, excellent Faradaic efficiency, and robust stability.

Single‐Cell RNA Sequencing Reveals the Heterogeneity in Differentiation Trajectory and Tumor Microenvironment Leading to More Aggressive Phenotypes of Papillary Thyroid Cancer in Children and Young Adult Patients

Advanced Science, EarlyView.
scRNA sequencing reveals distinct tumor ecosystem features in CAYA‐PTC, marked by enriched CD4T_Tfh, CD8T_Tex cells, and rapid malignant thyrocyte differentiation (absent of mild‐state BRAF‐like population) toward invasive states. Prominent emCAF_LAMP5 populations interact with endothelial cells and thyrocytes facilitate angiogenesis and metastasis ...

BInD: Bond and Interaction‐Generating Diffusion Model for Multi‐Objective Structure‐Based Drug Design

Advanced Science, EarlyView.
Can a generative model design molecules that truly understand their targets? BInD, a diffusion‐based framework, co‐generates 3D molecules and their interactions with proteins by learning target‐specific interacting patterns. With knowledge‐based guidance and NCI‐driven optimization, BInD balances affinity, geometry, and drug‐likeness – pushing the ...

Supramolecular Lubricating Hydrogel Microspheres Reshape Damaged Matrix Regeneration

Advanced Science, EarlyView.
The supramolecular lubricating hydrogel microspheres can provide stable mechanophysical protection at damaged matrix through interfacial hydration lubrication: in the early and middle stages, microspheres can actively provide microscale supramolecular lubrication (µ ≈ 0.04) for damaged matrix; in the late stage, the wear debris induced by shear and ...
