Scanning vibrating electrode technique

<p>Scanning vibrating electrode technique (SVET), also known as vibrating probe within the field of <a href="/facts/Biology/1M1ee3pB">biology</a>, is a <a href="/facts/Scanning_probe_microscopy/uJJPXQLN">scanning probe microscopy</a> (SPM) technique which visualizes <a href="/facts/Electrochemistry/C0RUWpBH">electrochemical</a> processes at a sample. It was originally introduced in 1974 by Jaffe and Nuccitelli to investigate the electrical <a href="/facts/Electric_current/Dc1xdnUX">current</a> densities near living cells. Starting in the 1980s Hugh Isaacs began to apply SVET to a number of different <a href="/facts/Corrosion/lIC7H4we">corrosion</a> studies.
SVET measures local current density distributions in the solution above the sample of interest, to map electrochemical processes <i>in situ</i> as they occur. It utilizes a probe, vibrating perpendicular to the sample of interest, to enhance the measured signal. It is related to scanning ion-selective electrode technique (SIET), which can be used with SVET in corrosion studies, and scanning reference electrode technique (SRET), which is a precursor to SVET.
