Devon Martin, Borosilicate and Fused-Silica Capillary Microelectrode Electrochemical Comparison and Micromanipulator Adaptor for Fused-Silica Capillary Microelectrodes
SAS 4201Borosilicate glass is the material predominately used for encasing carbon fiber (CF) microelectrodes for fast-scan cyclic voltammetry (FSCV) experiments. These capillaries insulate unexposed CF from the surrounding environment, while leaving a 150-200 um exposed CF tip in vivo that allows for electrochemical measurements of neurotransmitters. However, borosilicate glass commonly breaks during implantation; this can leave…
