Layered Nanoporous Platforms for SERS Sensing

Advanced Materials Interfaces, EarlyView.
Here, we present a detailed investigation of the SERS performance of layered nanoporous metals. The controlled deposition of well‐defined, stacked porous layers enabled a systematic analysis of the effects of multimetallic systems in SERS experiments. Numerical models are also used to support the experimental findings.

Facile Nanostructured Substrate Preparation Using Gold Nanocuboids for SERS

Nanomaterials and Nanotechnology, 2015
In the present work, we report a practical fabrication method of gold-aluminium substrates for surface en‐ hanced Raman spectroscopy. A commercial aluminium- foil was used to fabricate SERS substrates by depositing gold nanocuboids and faceted particles ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

GSH‐Responsive Nanoparticles Enhance Hepatocellular Carcinoma Immunotherapy Through Synergistic Effects of Cuproptosis and PI3K Inhibitor Combination

Advanced Science, EarlyView.
ABSTRACT Cuproptosis, an emerging form of programmed cell death, is capable of inducing mitochondrial dysfunction. Moreover, the PI3K‐AKT‐mTOR signaling pathway contributes to tumor cell progression by reprogramming mitochondrial morphology and function.

Compressive imaging of transient absorption dynamics on the femtosecond timescale

, 2019
Femtosecond spectroscopy is an important tool for tracking rapid photoinduced processes in a variety of materials. To spatially map the processes in a sample would substantially expand the capabilities of the method.

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.
