Untying Surface Chemistry and Emulsion Stability to Construct Multifunctional Pickering Emulsion SERS Sensors for Pretreatment‐Free Quantitative Analysis in Bio‐Media

open access: yesAdvanced Science, EarlyView.
A dual‐particle interfacial self‐assembly approach is used to create surface‐accessible Pickering emulsions with Au@Prussian blue nanoparticles acting as the functional component. These emulsions have strong plasmonic properties and are equipped with molecular sieves and internal standards.

SGCD: High‐Resolution Spatial Domain Characterization via Data Interpolation and Cell‐Type Deconvolution

open access: yesAdvanced Science, EarlyView.
SGCD presents a novel approach for tissue spatial domain identification by employing interpolation to estimate inter‐spot gene expression and deconvolution to resolve cell‐type composition in both sampled and interstitial regions. By integrating gene expression, cell type, and spatial coordinates within a graph contrastive learning framework, SGCD ...

Quantum Valley Hall Effect‐Based Coupler with Continuously Tunable Transmission for Topological Information Communication

open access: yesAdvanced Science, EarlyView.
The quantum‐valley‐Hall‐based bridge boundary has the frequency dependent wave localization. Utilizing the frequency dependency, this article experimentally shows the micro‐electromechanical‐systems‐based topological coupler with continuously tunable transmission coefficients by the frequency of interface modes within a single bulk bandgap. Furthermore,

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.
