A three-dimensional printed cell for rapid, low-volume spectroelectrochemistry.


ABSTRACT: We have used three-dimensional (3D) printing technology to create an inexpensive spectroelectrochemical cell insert that fits inside a standard cuvette and can be used with any transmission spectrometer. The cell positions the working, counter, and reference electrodes and has an interior volume of approximately 200 ?l while simultaneously providing a full 1-cm path length for spectroscopic measurements. This method reduces the time required to perform a potentiometric titration on a molecule compared with standard chemical titration methods and achieves complete electrolysis of protein samples within minutes. Thus, the device combines the best aspects of thin-layer cells and standard potentiometry.
