Abstract :
TEOS and/or TEOS/HFE plasma polymerized thin films, exposed or non-exposed to ultraviolet (UVC) radiation, were obtained on gold electrodes and tested for electrochemical measurements. All films presented good performance on electrochemical measurements. The electronic signal does not change significantly after 24h on physiologic serum but thin TEOS films allow ion permeation. Thus, these films are useful as membranes to reference and measuring electrodes.
