Article Title: Capture of Single Silver Nanoparticles in Nanopore Arrays Detected by Simultaneous Amperometry and Surface-Enhanced Raman Scattering

doi: 10.1021/acs.analchem.8b05748

Figure Lengend Snippet: (A) Schematic cross-sectional diagram of a single nanopore in an NEA with AgNPs captured by applied voltage. The potentiostat is used to control the potential at the Au-ring working electrode vs the Pt quasi-reference electrode (QRE). A 532 nm incident field is illuminated from the top. (B,C) SEM images of nanopores. (D) Cross-sectional image of the NEAs.

Article Snippet: In order to apply voltages to the recessed ring electrode of the NEA, CH Instruments electrochemical workstation software version 16.07 was used; DC voltages were applied using Multi-Potential Steps mode ( Figure S3A ), and the AC Impedance-Time technique was used to apply the AC-voltage programs ( Figure S3B ).

Techniques: Control
