Electroanalytical devices with pins and thread. Issue 1 (9th November 2015) - Glavan, Ana C.
Abstract : This work describes the adaptive use of conventional stainless steel pins—used in unmodified form or coated with carbon paste—as working, counter and quasi-reference electrodes in electrochemical devices fabricated using cotton thread or embossed omniphobic R F paper to contain the electrolyte and sample. Abstract : This work describes the adaptive use of conventional stainless steel pins—used in unmodified form or coated with carbon paste—as working, counter, and quasi-reference electrodes in electrochemical devices fabricated using cotton thread or embossed omniphobic R F paper to contain the electrolyte and sample. For some applications, these pin electrodes may be easier to modify and use than printed electrodes, and their position and orientation can be changed as needed. Electroanalytical devices capable of multiplex analysis (thread-based arrays or 96-well plates) were easily fabricated using pins as electrodes in either thread or omniphobic R F paper.
