A new molecularly imprinted sensor was developed based on an electroluminescent molecularly imprinted polymer (MIP) membrane and used for doxycycline determination. The MIP was prepared by electropolymerization of pyrogallol doped with alizarin red. An electrochemiluminescence (ECL) signal was produced by the oxidation of the poly-pyrogallol polymer and reaction with alizarin red. The luminescence intensity was enhanced by doxycycline molecules which were re-adsorbed in cavities in MIP due to the energy transfer of the doxycycline oxidized intermediate to alizarin red. The changes of ECL intensities were linear with the concentrations of doxycycline in the range of 2 × 10(-10) to 5 × 10(-8) mol L(-1). The detection limit was 5.17 × 10(-11) mol L(-1). This method was utilized to determine doxycycline residuals in fish muscles with satisfactory results.

Reactive oxygen and nitrogen species are small reactive molecules derived from elements in the airoxygen and nitrogen. They are produced in biological systems to mediate fundamental aspects of cellular signaling but must be very tightly balanced to prevent indiscriminate damage to biological molecules. Small molecule probes can transmute the specific nature of each reactive oxygen and nitrogen species into an observable luminescent signal (or even an acoustic wave) to offer sensitive and selective imaging in living cells and whole animals. This review focuses specifically on small molecule probes for superoxide, hydrogen peroxide, hypochlorite, nitric oxide, and peroxynitrite that provide a luminescent or photoacoustic signal. Important background information on general photophysical phenomena, common probe designs, mechanisms, and imaging modalities will be provided, and then, probes for each analyte will be thoroughly evaluated. A discussion of the successes of the field will be presented, followed by recommendations for improvement and a future outlook of emerging trends. Our objectives are to provide an informative, useful, and thorough field guide to small molecule probes for reactive oxygen and nitrogen species as well as important context to compare the ecosystem of chemistries and molecular scaffolds that has manifested within the field.
