Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

Advanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Toward Prostate Cancer Early Warning with a Self‐Powered Wearable Biosensing Platform Integrated with Machine Learning

Advanced Science, EarlyView.
ABSTRACT Current prostate cancer detection methods remain limited in non‐invasiveness and specificity, prompting interest in urinary biomarkers such as sarcosine. Here, we report a urine‐powered wearable platform for non‐invasive sarcosine detection as a proof‐of‐concept for decentralized early warning.

Mapping the Reactivity of the C═C Bond of Cyclic Enol Ether Derivatives of Sugars: Nucleophilicity Parameters of Glycals

Angewandte Chemie International Edition, EarlyView.
Endo or Exo? The first quantitative kinetic mapping of the nucleophilic reactivity of endo‐ and exo‐glycal compounds highlighted that endo‐glycals are typically 102 times less reactive than their corresponding parent cyclic enol ethers while exo‐glycals are 103 more nucleophilic. This experimental and computational structure–reactivity study highlights

Diffusion Behaviours of Three Thioureido Imidazoline Corrosion Inhibitors in a Simulated Sediment Layer

International Journal of Electrochemical Science, 2018
In the present work, the diffusion behaviours of three thioureido imidazoline inhibitors (SOIMS, SOIM and OIM) in a simulated sediment layer were investigated by ultraviolet-visible spectrophotometry (UV-vis) and potentiodynamic polarization in a ...

A Multiepitope‐Based Lateral Flow Assay for Leprosy Antibodies

Analysis &Sensing, EarlyView.
An innovative lateral flow assay for leprosy diagnosis is based on gold nanoparticles and synthetic Mycobacterium leprae epitopes conjugated to keyhole limpet hemocyanin protein to enhance antibody detection. This strategy provides a rapid, accurate, and low‐cost approach for resource‐limited settings, enabling the early detection of infection. Leprosy
