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.

Fluorescence spectroscopy is a routine tool for studying cellular and molecular visualization, flow cytometry, medical diagnosis, forensic medical examination, genetic analysis, and also an analytical method. However, most available organic dyes used to produce an optical signal have a number of important limitations, such as hydrophobicity, low quantum yield, and low photostability.
