SEED: Product Introduction
Scanning Electrometer for Electrical Double-layer (SEED) is an electro-optical instrument to quantitatively measure local electrochemistry on a spot of an electrode. The spot size is defined by the diameter of the laser beam, typically ranging from 10 to 50 microns. By scanning the laser, the electrochemical activity on the electrode can be quantitatively mapped.
The instrument has an all-inclusive single electronics module to obtain: SEED signal for local electrochemistry, scan the sample for multiplexing and combinatorial analysis, conventional electro-analytics, such as cyclic voltammetry on the whole electrode. The multi-mode analysis will allow deconvolution of complexities of electrochemical process.
​
Two modification/attachment to the basic model will allow measurement of dynamic ellipsometry and extend the measurement to more complex analysis. Sample chambers are available to perform single and multi-analyte analysis on small sample volume, as small as 10 microliters. A full line of accessories from electrodes and chips to buffer are available as one-stop-shop solution.

As an example, the instrument can electrochemically read binding to a microarray with over 50 spots in about 10 minutes on a single electrode with target DNA concentration at attomolar level and measure oxidation and reduction reactions from ~0.5 zeptomole or ~300 molecules.
