Tri‐Layer Solid‐State Nanopore Arrays with Crosstalk Suppression for High‐Throughput, Femtomolar‐Level Biosensing

Advanced Science, EarlyView.
The critical pore spacing—approximately twenty times the pore radius—required to minimize electric field coupling is determined via finite element analysis. A multi‐layered Al2O3/Au/Si3N4 nanopore structure fabricated by helium ion beam lithography is proposed, enabling quantitative analysis of the target analyte while mitigating inter‐pore crosstalk ...

Peptide Receptor‐Functionalized AuNP‐Embedded Zwitterionic Biopolymeric Nanohydrogel for Electrochemical Sclerostin Sensing

Advanced Science, EarlyView.
We report an electrochemical biosensor that employs biopanning‐derived affinity peptides as selective receptors on a multifunctional chitosan–zwitterionic–gold nanoparticle (CS–ZI–AuNPs) nanohydrogel interface. The CS–ZI–AuNPs nanohydrogel exhibits antifouling properties, abundant sites for stable peptide immobilization, and efficient electrochemical ...
