Electrochemically created highly surface roughened Ag nanoplate arrays for SERS biosensing applications

Electrochemically Created Highly Surface Roughened Ag Nanoplate Arrays for SERS Biosensing Applications.

Highly surface-roughened Ag nanoplate arrays are fabricated using a simple electrodeposition and in situ electrocorrosion method with inorganic borate ions as capping agent. The electrocorrosion process is induced by a change in the local pH value during the electrochemical growth, which is used to intentionally carve the electrodeposited structures. The three dimensionally arranged Ag nanoplat...

Highly Efficient Surface Enhanced Raman Scattering (SERS) Nanowire/Ag Composites

Introduction: Optically based sensing provides advantages over electronic sensing because optical spectra can uniquely fingerprint a chemical compound, significantly reducing false alarms and simplifying the detection process. In addition, light can easily be directed over long distances, enabling remote sensing. One of the most promising optical sensing techniques is surface enhanced Raman sca...

Preparation of electrochemically active silicon nanotubes in highly ordered arrays

Silicon as the negative electrode material of lithium ion batteries has a very large capacity, the exploitation of which is impeded by the volume changes taking place upon electrochemical cycling. A Si electrode displaying a controlled porosity could circumvent the difficulty. In this perspective, we present a preparative method that yields ordered arrays of electrochemically competent silicon ...
