Abstract

Since the common anaesthetic drug 2,6-diisopropylphenol (propofol) has a narrow physiological range, the administration of this drug could be improved through the development of a feedback-controlled delivery system. An evaluation of several carbon filaments was conducted to determine their capability to serve as the detecting element in such a system. Planar electrochemical cells (PECs) were fabricated with working electrodes made from three carbon filaments: Goodfellow (GF) carbon fibers, 11μm diameter; Bioanalytical Systems (BAS) carbon fibers, 9μm diameter; Specialty Materials (SM) glassy carbon monofilaments, 34.5μm diameter. The cells were used to make multiple, successive determinations of propofol – via cyclic voltammetry – in both pH ~7.0 aqueous and acetonitrile solutions. All three electrodes showed significant fouling in pH ~7.0 aqueous solutions. The SM electrodes had moderate fouling in acetonitrile solution, while both GF and BAS electrodes showed minimal fouling in acetonitrile solution.
