Electrocatalytically Amplified Immunosensing Enabled by Titanium Oxynitride‐Supported Ru Nanodots on Graphene Oxide Hybrid Architecture

Small, EarlyView.
A synergistic effect among the electrocatalytic Ru/TiON‐GO nanocomposite, biorecognition elements, and the [Fe(CN)6]3−/4− redox probe for highly sensitive and selective impedimetric detection of PSA protein in human serum was demonstrated. The immunosensor exhibited a limit of detection of only 0.06 ng mL−1 PSA protein, underscoring the importance and ...

From Planar to Patterned: Structured Boron‐Doped Diamond Electrodes for Electrochemical Sensing

Analysis &Sensing, Volume 6, Issue 5, September 2026.
Structuring transforms boron‐doped diamond (BDD) from a planar electrode into a versatile sensing platform. This mini‐review surveys top‐down and bottom‐up fabrication routes, shows how structural design reshapes electrochemical behavior—enhancing current response, lowering oxidation potentials, and improving selectivity and stability—and then ...
