Abstract EN
A new biomimetic sensor for leucomalachite green host-guest interactions and potentiometric transduction is presented.
The artificial host was imprinted in methacrylic acid or acrylamido-2-methyl-1-propanesulfonic acid-based polymers.
Molecularly imprinted particles were dispersed in 2-nitrophenyloctyl ether and trapped in poly(vinyl chloride).
The potentiometric sensors exhibited a near-Nernstian response in steady state evaluations, with slopes and detection limits ranging from 45.8 to 81.2 mV decade-1 and 0.28 to 1.01 μg mL-1, respectively.
They were independent from the pH of test solutions within 3 to 5.
Good selectivity was observed towards drugs that may contaminate water near fish cultures, such as oxycycline, doxycycline, enrofloxacin, trimethoprim, creatinine, chloramphenicol, and dopamine.
The sensors were successfully applied to field monitoring of leucomalachite green in river samples.
The method offered the advantages of simplicity, accuracy, applicability to colored and turbid samples, and automation feasibility.
