Electroanalytic properties of unmodified and polyaniline-modifi ed planar sensors sensitive to doxycycline

Doxycycline has a wide range of antimicrobial and anti-infl ammatory properties and is used to treat various infectious diseases. Spectroscopic, chromatographic, electrochemical, immunoassay and other methods are used to determine tetracycline antibiotics in various objects. Planar sensors allow express detection of antibiotics in small sample volumes. Planar potentiometric sensors based on ion associations doxycycline – tetraphenylborate (Copt = 2–3%), modifi er – polyaniline, for the quantitative determination of doxycycline have been developed.
