Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Xolography for Rapid Volumetric Production of Objects from the Nanoscopic to Macroscopic Length Scales

open access: yesAdvanced Materials, EarlyView.
This article explores the development of materials with multi‐scale control at the nanoscale (<100 nm), micrometer‐scale (80 µm), and macro‐scale (multi‐component geometries). This is achieved by applying polymerization‐induced microphase separation (PIMS) process via volumetric 3D printing (Xolography), expanding the design space for functional ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

open access: yesAdvanced Materials, EarlyView.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Sonodynamic and Bioorthogonal Sonocatalytic Thrombotic Therapy Based on AIE Cationic Tetranuclear Ir(III) Complex Nanoplatform Guided by NIR‐Chemiluminescence Imaging

open access: yesAdvanced Materials, EarlyView.
AIE‐active tetranuclear Ir(III) complex Ir‐4 as a sonosensitizer/sonocatalyst is formulated into a nanoplatform with an H2S donor. Ir‐4@S‐R NPs achieves combined endogenous NIR chemiluminescence imaging, sonodynamic therapy and release of H2S in situ by a bioorthogonal sonocatalytic reaction in vivo, achieving safe thrombolysis and anti‐inflammatory ...

Environmental Control of Ferroelectricity in Hafnia Films

open access: yesAdvanced Materials, EarlyView.
A reversible transition from nonferroelectric to ferroelectric behavior is achieved in hafnia films by modulating the surrounding atmosphere. The domain relaxation dynamics exhibit high sensitivity to environmental factors, including gas composition (ambient, N2, CO2, O2) and relative humidity, highlighting the crucial role of the measurement ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Overcoming Material Incompatibility via 2D Free‐Surface Engineering

open access: yesAdvanced Materials, EarlyView.
A scalable post‐epitaxial strategy introduces a sub‐nanometric 2D free surface (2DFS) at the heterointerface, effectively decoupling lattice‐mismatched layers. This process significantly reduces strain‐driven defects and dislocation density in Ge/Si heterostructures. The resulting bulk‐like material quality, validated by advanced microscopy and optical
